S&C Electric Company: Moving Beyond Average Reliability Metrics

Reliability matters to all stakeholders. While the most used metrics for reliability have changed relatively little since the 1970s, technology and customers’ use of electricity is evolving, placing ever-growing importance on electricity distribution reliability. There is often a disconnect between the average systemwide performance metrics such as SAIFI SAIDI and MAIFI and the performance experienced by individual customers.

This presentation lays out S&C’s conclusions that a broader suite of reliability metrics should be used, placing more weight on customer-centric metrics, some of which will be familiar, and some that deserve more attention. Looking to the future, as we transition toward an energy system with integration of much greater volumes of distributed generation and the electrification of transportation, distribution system stability metrics will likely become useful.

Navigating a Just Transition: Investment, Power, Place, and Policy Dynamics in Australia + EESA QLD Chapter AGM 2022

The EESA Qld AGM 2022 was followed by a presentation on Navigating a just transition: investment, power, place, and policy dynamics in Australia.

Synopsis: Decarbonisation is reshaping Australia's economic foundations and will be a critical determinant of future prosperity. But a lot needs to go right to reap the benefits of a low carbon transition. Success will turn on solving challenges of technical complexity, scale, interdependence, and pace of structural changes across energy and manufacturing systems. This will require the coordination of three fundamental forces: investment capital; energy supply and demand; and policy in key places and regions across the country. 
 
This presentation will explore major challenges and potential solutions to the challenges facing decarbonisation of key industrial regions in Australia. The respective roles of government and industry will be a key focus.

2021 Victorian AGM - Distributed Energy Resources: Hosting Capacity as a Service

Main Webinar Topic - Distributed Energy Resources: Hosting Capacity as a Service

Distribution Network Service Providers (DNSP) are evolving network infrastructure to accommodate Distributed Energy Resources (DER) such as solar PV, batteries and EVs. Low voltage networks were not designed for two-way power flows and their visibility has been kept poor by economic choice.

DNSPs are now making efforts to monitor LV network, estimate its state and even publish available capacity dynamically. This will not only provide network businesses a framework to decide most efficient investment enabling DERs but will also unlock information to the third-part service providers / aggregators to provide most value to the consumers. Regulatory mechanisms are also catching up with the transformation taking place by providing more guidance on the value of DER, identifying the cost-benefit analysis that includes benefits for the entire eco-system (networks, environment, wholesale market etc.). This webinar will present the advances and explore if DER hosting capacity can be provided as a service, who can best provide it and what capabilities need to be developed to achieve such an outcome.

Australia's Path to Net Zero 2050

The challenge that has been set for the world’s nations is to achieve “net zero by 2050” – to limit global warming to < 2 degrees C. The presentation seeks to develop a realistic high-level analysis and model of the transition to technological “net zero by 2050” for Australia, to use this model to provide a basis for a plan for the transition to 2050, and broadly quantify the magnitude of the tasks ahead.

The approach is to:

• Understand which parts of the economy produce CO2

• Model electricity as it is generated today, and how it can be decarbonized by 2050

• Model all energy consumption in the economy and how fossil fuel use can be eliminated by 2050 via renewably generated electricity, and green hydrogen and its derivatives.

CIRED Paper 887 - Madrid 3-6 June 2019

Electrical distribution transformers are one of the most expensive components in the distribution grid. For  several years Itron has developed algorithms (coupled thermal and electrical models of distribution transformers) embedded in a Smart meter. These embedded models simulate thermal and electrical behavior of the transformer in the time domain. This paper presents the latest developments on the thermal model based on the two standards IEC 60076-7 and IEC60076-16 (Annex A2),.The purpose is to introduce, into the heat transfer differential equations of the distribution transformer, the effect of two harmonic indicators deduced from the current waveforms of each phase on the LV side of the transformer.

The objective is to offer to the DNO a good solution to minimize the risk of unexpected outage as their distribution transformer installed base is continually being monitored and kept in a security domain.

Compact Fluorescent Lamps (CFL) - Implications for Distribution Networks

CFLs are a nonlinear load hence inject harmonics into the electrical network. The CFL use electronic ballasts and the design of these have an enormous impact on the electrical performance of the CFL. If widespread adoption of CFLs occurs the combined effect of all these small sources can be just as detrimental as one large source, and is even harder to mitigate due to their distributed nature.

Conductor Recognition Using Semantic Segmentation

Webinar Overview

Worldwide electricity distribution companies are moving towards risk-driven network replacement and maintenance strategies, and part of the risk assessment is to evaluate or estimate the asset condition. Unison has an ageing overhead conductor fleet consisting of over 4,200 km of high voltage lines, there are approximately 500 km of 7/0.064 Plain Hard-drawn Copper (PHC) 11 kV conductor in the fleet. The conductor has low tensile strength and an aged installation profile. Research that Unison conducted in 2018 identified the conductor’s visual appearance as a key indicator for condition assessment – hence Unison is currently developing a system that can use conductor images obtained by drones, to automatically evaluate the appearance and condition of the conductor.
This presentation will show the process followed to use machine learning and semantic segmentation to recognise/identify the overhead conductor region of interest in images with natural backgrounds. Such segmentation of the conductor is a required first step before evaluating the conductor appearance and condition, which also uses automated machine learning techniques

Dynamic Line Rating Application in Generator Interim Access (GIA)

Generator Interim Access (GIA) is a generator connection solution introduced by Western Power to allow new generators to be connected to the SWIS at low costs under a constrained access arrangement. With more GIA generators being connected and new network limitations, GIA generators are being constrained more often. This has impacted not only the cost to the energy market but also introduced challenges for AEMO to maintain a stable system frequency and manage sufficient ancillary services, such as load following and spinning reserve. One solution for reducing the impacts is to increase the network capacity by introducing dynamic line ratings in the GIA Tool.

This application of the dynamic line ratings is to dynamically calculate the line ratings, which are based on the ESAA D(b)5 1988 line rating methodology, using real-time ambient temperature data and historical PoE (probability of exceedance) data of solar radiation in GIA constraint equations. The objective is to increase the summer thermal ratings of critical transmission lines to capacity levels similar to their corresponding winter thermal line ratings. The implementation philosophy is to have a non-complicated but reliable and auditable dynamic line rating calculation. This presentation will discuss the implementation and benefits of this dynamic line rating application.

Electric Energy Security and the Role of Nuclear Energy in Australia. "A Sustainable and Secure Electric Energy Solution"

Under the Australian Constitution it is the State and Territory governments, not the Commonwealth which has responsibility for energy. Victoria is one of three states (the others being New South Wales and Queensland) which have laws prohibiting nuclear power, while the other states and territories have no prohibitions. With South Australia considering the nuclear fuel cycle, and there being a possible future energy supply via the National Electricity Market (NEM), this has direct relevance to Victoria.

Flicker Propagation and Attenuation in Power Systems: Review of Results from Field Measurements, Controlled Experiments and Theoretical Work

Voltage fluctuations leading to lamp flicker tend to propagate from its origin to other parts of power systems. When flicker propagates from the bus bar of its origin, to higher voltage bus bars (upstream), the level of attenuation exhibited is usually governed by the ratio of fault levels at the two bus bars. The flicker that is present at an upstream bus bar, although small, can still propagate along connected feeders to other lower voltage (downstream) load bus bars exhibiting some level of attenuation.

Insulation Co-ordination for Transmission & Distribution Equipment

EESA is pleased to present Colin Lee, a long-time electricity industry professional, who will present on the topic of Insulation Coordination.

Insulation coordination encompasses the studies and steps used to select the insulation strength of electrical equipment so that it can survive the operating and transient overvoltages (from lightning and switching) which it is subjected to over its life. A good knowledge of insulation coordination will generally lead to the optimal amount of insulation, but to adequately address lightning strikes some form of overvoltage protection is still required, such as the installation of shielded earthwires or surge arresters.

Colin will go through the insulation coordination principles outlined in the various standards and how to apply it using worked examples to select the insulation requirements for transmission and distribution equipment.

Large-scale battery energy storage systems are already providing a range of valuable services to the National Electricity Market. These are incredibly flexible assets, highly configurable in the value stack they can provide, and in the support they offer to the national grid.

As the penetration of variable renewable energy increases in coming years, and the synchronous generation fleet retires, the power system will face continued and emerging challenges; issues such as declining inertia and system strength, the evolving renewable energy zone and transmission landscape, and the changing generation profile to meet demand. Large-scale batteries are poised to play in an increasingly crucial role in the electricity grid of the future. This presentation will show how large-scale battery storage is the Swiss Army Knife of the renewables transition. 

Costs are falling and energy market prices evolving in favour battery projects. Yet building a commercial business case for a grid scale battery remains a challenging feat. It will need a careful eye on regulatory reform and market opportunities, along with increasing sophistication in how the technical capabilities of batteries can best be commercially deployed to provide maximum value. Insights will be presented into these evolving opportunities to build a value-stacked business case, including the key technical and commercial interrelations that can drive best project outcomes.

Load Control of Plug-in Electric Vehicles for Enhanced Power System Responsiveness

Responsive load control offers a particularly effective approach to compensating for the variability inherent in large-scale renewable generation, and mitigating the effects of generation and transmission outages. Furthermore, as plug-in electric vehicles grow in popularity, scheduling their charging load will become vitally important to prevent local overloads, and to ensure optimal use of generation resources. Fortunately expansive communications networks and advances in distributed control algorithms facilitate precise, non-disruptive forms of load control.

Real-time Simulation: The Difference for de-risking Grid Modernization Projects (Recording)

This presentation will explore the role that real-time simulators and hardware-in-the-loop (HIL) testing can have in innovative projects at electric utilities and other institutions. HIL testing allows power system professionals to de-risk the integration of novel systems, anticipate and mitigate negative interactions, and optimize device performance by connecting real devices to a simulated network. HIL testing provides a depth of analysis and systems-level testing approach that are highly beneficial, and often critical, in the modern power system. Inverter-based renewable energy resources, communication protocol-based protection and control, and other grid modernization technologies can create vulnerabilities that conventional modelling and testing processes are often blind to. Hardware-in-the-loop testing allows engineers to anticipate these issues, preventing mis operation and negative interactions which may result in outages or damaged equipment.

The RTDS® Simulator is the industry standard for real-time power system simulation. Hardware-in-the-loop testing with the RTDS Simulator has been applied by power system innovators worldwide to enable a secure global energy transition. Applications of this technology include de-risking the large-scale integration of renewable energy resources, cybersecurity testing, microgrid protection and control testing, distribution automation and intelligent switchgear testing, de-risking HVDC and FACTS integration, wide area protection and control studies, power electronics testing, and more. This presentation will explain the theory and benefits of real-time simulation, describe the hardware and software required for HIL testing, and provide examples of real-world case studies where real-time simulation has been used to the advantage of grid modernization projects.

RESILIENCE OF DISTRIBUTION GRIDS

Resilience is a multi-faceted concept which can be interpreted and defined in several ways by organizations around their world, based on their practices and experiences with extreme events. In the context of distribution systems, resilience can be widely defined with respect to system’s ability to withstand rare and extreme events (snow storms, hurricanes, earthquakes, terroristic attacks) and quickly recover to its pre-event resilient state.

In this webinar you will learn what the definitions of these metrics are, what the significance of each metric is, common practices for improving metrics to improve customer satisfaction with electricity service, and how some of the metrics are used by regulators to penalise or incentivise network service providers to invest in network technology solutions, as well as maintenance and operation practices towards improving the reliability of their networks. In the end, some of the benefits realised by these investments can be passed on to consumers through rate reductions.

Solar Enablement Initiative, State Estimation on the Distribution Network

 

Solar Enablement Initiative: Applying State Estimation to Distribution Networks to Facilitate a High DER Future

The Solar Enablement Initiative (SEI) is a collaborative project which has refined and applied a novel State Estimation Algorithm (SEA) across eight feeders within three Australian distribution networks to achieve a level of visibility over network performance previously unimaginable without significant capital investment. Once the state of the network is known a distribution operator can define a safe network operating envelope within which active DER can be dynamically managed, an important step to facilitate increasing levels of distributed energy resources (DER) on the network and to unlock the value of the network and DER for customers.

This presentation will demonstrate how the SEA developed in a research setting has been successfully translated into a real world industry setting as part of a small scale trial.

This presentation will cover:

  • Novel UQ-developed state estimation algorithm
  • Results of the estimator as applied to the project‚Äôs trial feeders
  • Dynamic Operating Envelopes for DER
  • Cleveland Case Study ‚Äì dynamic export from a PV system based on near real-time network conditions
  • Future work in this space

Synchronised Phasor Measurement

You must be a logged in paying / financial member to download this file

Synchronism-Check Application Over a Wide-Area Network

Recent technological developments have enabled solutions to power system protection and control issues that have previously been either too difficult or too expensive to implement. Synchronising generators to the power system requires analogue and digital information from both the generator and the network. Transmitting information via copper cabling requires the power station and the point of connection to the power system to be in close proximity, but how do you achieve this when the sites are 1 kilometre or more apart?

This paper describes the first stage of a synchronism-check upgrade to the Whakamaru Power Station and its connection to the 220 kV transmission network. The paper describes the design installation, commissioning, and operation of the first stage of the scheme. The scheme has been designed to allow any of four 27 MVA hydro generators to be synchronised from any of four 220 kV line voltage transformers. The choice of hardware and the design process have allowed for future enhancements such as the addition of an autosynchroniser. The scheme has been designed to protect against the following:

  • Misoperation of the existing autosynchroniser equipment
  • Incorrect connection of the synchronising signals to the autosynchroniser
  • Manually synchronising machines out of phase

The scheme employs a real-time automation controller using IEC 61131 logic. The main unit is located at the power house and connected via 1 kilometre of single-mode fibre to the remote unit at the ODM. Analogue and digital information is transmitted between the ODM and the power house using a high-speed, industrial-based communications protocol known as EtherCAT. Synchronised sampling of the local and remote measurement units avoids the need for an external GPS clock, reducing complexity and improving the availability of the system.

Synchronous services markets: maximising the capacity of existing transmission networks

Old synchronous generators are quickly being replaced by cleaner, cheaper providers but ones that can’t provide synchronous services that used to come for free. If only there was a way to keep receiving these services, without the pollution.

There is.

The Synchronous Services Market rule change request is designed to provide a market and dispatch mechanism alleviating emerging network constraints i.e. stability, inertia, voltage and fault level.  It is based on Tasmanian lived experience and is currently going through a consultation process with the market rule makers, with decision pending mid-2022.

The Impact of Small Scale Solar PV on Power Quality: An Empirical Study

Australia has perhaps the highest penetration of small scale solar PV generation in the world. There is conjecture with regard to the impact that the inverters used to facilitate connectivity between solar PV generators and the grid will have on power quality disturbance levels. In this paper power quality data collected from several thousand low voltage sites has been analysed in order to facilitate an empirical investigation of the impact of small scale solar PV generation on PQ disturbance levels. The specific disturbances investigated are steady state voltage voltage unbalance and voltage THD. The earliest data which has been is from 2009 when solar PV penetration was low in Australia and concludes with data from 2019. The study outcomes suggest that solar PV generation is leading to a change in the profile of voltage across the day and is increasing voltage magnitudes to above light load levels at some sites. There is little evidence to support assertions that solar PV systems are increasing either voltage unbalance or voltage THD magnitudes.

The Technology, its Capabilities and Opportunities for Australia

Under the Australian Constitution it is the State and Territory governments, not the Commonwealth which has responsibility for energy. Victoria is one of three states (the others being New South Wales and Queensland) which have laws prohibiting nuclear power, while the other states and territories have no prohibitions. With South Australia considering the nuclear fuel cycle, and there being a possible future energy supply via the National Electricity Market (NEM), this has direct relevance to Victoria.

Using High Resolution Oscillography to Improve Switching of Transformers

Energisation of power transformers at a random point-on-wave can result in inrush currents that far exceed the full-load rating of the transformer resulting in power quality issues and stress on equipment. Controlled switching, in which the breaker is closed at a point-on-wave chosen to minimise the inrush current, greatly reduces the inrush current and its negative effects.

This presentation will describe the design and commissioning of a controlled switching scheme using high resolution oscillography. This technology has been used to optimally energise and de-energise a high voltage power transformer.

Virtual Inertial to curb Frequency Instability

SYNOPSIS

Inertia in power systems has been traditionally determined by considering all the rotating masses directly connected to the grid that limits the fast speed changes in rotating parts of a power system and subsequently limits the fast frequency oscillations and guaranties the power system stability. Due to the inertia-less nature of power electronics interface (i.e., converter/inverter), the increasing penetration of RESs (renewable energy sources) and DGs (distributed generators) will lead to the further reduction of system inertia and will also affect the damping properties of the system.

One of the solutions toward stabilizing such power systems with massive DG/RES penetration is by synthesizing additional artificial inertia and damping properties virtually. VI (Virtual Inertia) synthesis and control provides a thorough understanding of the basic principles, synthesis, analysis, and control of virtual inertia systems using the latest technical tools to mitigate power system stability and control problems under the presence of high RES penetration.

This Seminar presentation provides a survey on the fundamental aspects of the virtual inertia for Microgrid control and more specifically for a real case study (Broome city) by using of battery energy storage system (BESS), as one of the novel VI emulated techniques, in enhancing system inertia. Also the following items will be presented and discussed:

  1. Theoretical advantages of implementing BESS as VI:
  • Reduction in frequency nadir (Minimum Frequency) and decrease the deviation of the frequency
  • Less overshoot and faster transient or respond time
  • Less RoCoF (Rate of Change of Frequency) and less steep gradient
  • Faster recovery time to the nominal frequency

 

  1. The concept of new Inverter Based VI definitions in the power systems:
  • Grid Following and Grid Forming inverters
  • Synchronverter
  • VISMA (Virtual Synchronous Machines)
  • VSYNC topology
  • Droop-based approach

 

  1. Simulation of installing 2 x 800KVA BESS in Broome city as a real practical case study DIgSILENT software
  • Model presentation of Broome network and Danfoss inverter (Manufacturer of Broome’s Inverters) topology
  • Simulation results of Broome network frequency responses in the presence of BESSs
  • BESS’s Droop setting to achieve optimum response by considering comprehensive Power Factory cloud event simulation and step load/generation disturbances

Whydrogen. What is driving the surge of current interest and investment

These days even someone who isn’t a self-confessed energy nerd would be hard pressed to avoid the all the news about hydrogen. Over the last year or so hydrogen has gone from being an interesting idea to being broadly recognised as a key part of our global energy future.

What has caused this change? Hydrogen has certainly been discussed previously, but hasn’t ever really taken off before. Why is it different this time?

Equally, for all the talk and excitement: there are a lot of plans, but relatively little physical deployment.  What is stopping (or at least slowing) the delivery of the promise at the moment and what are the paths to overcome these obstacles?

Speakers

Cam Potter

Cam has had the opportunity to work across a range of roles, covering most of the function in the electricity sector. He has worked in academia while successfully completing a Ph.D. at the university of Tasmania. He has worked as a consultant, both with US-based 3TIER (now owned by Vaisala) and as an independent consultant. Cam has also worked for Hydro Tasmania and so understands the generation side of the energy industry – particularly regarding time spent leading the analysis for Battery of the Nation. After that Cam spent some time at AEMO, the system operator. Now he is working for Fortescue Future Industries, working to develop large energy consuming plant (although the breadth and scale of FFI’s ambition means that the simple definitions don’t necessarily apply).
