Network Connection Opportunity Maps
25 September 2019 - Frank Bucca and Matthew Brooks

SYNOPSIS

The Network Opportunity Maps was developed subsequent to the development of the DAPR Network Mapping Portal. The mapping portal was seen as a powerful tool to provide information in the public domain in an easy to understand and accessible fashion. The purpose of the Network Opportunity Maps is to inform developers, local councils and other regulatory bodies and parties of where spare network capacity exists to enable lower cost connections to the network. This will reduce the time required for developers and other network connection applicants for identifying suitable development sites. This will ultimately improve network utilisation and lead to lower network costs to all customers.

Distribution Voltage Management, High PV Penetrations and the 230V Transition
27 August 2019 - Peter Kilby

BACKGROUND FOR THIS TOPIC

There has been a rapid increase in the connection of distributed solar photovoltaic (PV) systems in Queensland over the last decade. This has led to a range of challenges for the distribution networks including reverse flows and voltage rise on distribution feeders which traditionally only supplied loads. As a result there has been an increased range in steady-state voltage regulation on the low voltage (LV) network. Reductions in LV levels to transition from the 240V to the 230V standard have helped reduce overvoltage, increasing PV hosting capacity. Ongoing increases in steady state voltage rise on distribution feeders, associated with rising PV penetrations, will continue to increase voltage regulation. This becomes problematic where voltages already swing significantly between the upper (253V) and lower (216V) statutory limits as is observed on rural networks and increasingly networks with high existing PV penetrations.

This presentation will cover:

• the growth of PV systems on Queensland’s LV distribution network leading to reverse flows;
• the traditional distribution voltage management approaches undertaken in Queensland;
• the 230V transition and some results from LV network monitoring;
• the increased voltage regulation associated with high PV penetrations and reverse flows;
• some of the emerging approaches and technologies to maintain acceptable voltage regulation and enable increasing PV penetrations.

Electrolysis Corrosion Caused by Stray Current
14 August 2019 - Jim Hickey

SYNOPSIS

Corrosion of metals can be categorised into four main types. The least aggressive forms of corrosion can be attributed to general corrosion where anodes and cathodes distribute corrosion currents on the surface of a metal which are typically in the order of µA or smaller. A more aggressive type of corrosion can be found when the anode/cathode driving voltage increases due to contact between dissimilar metals in a common conductive medium such as water or earth. This type of corrosion is known as galvanic corrosion and typically is another order of magnitude higher then general corrosion. The next level more aggressive then galvanic corrosion is electrolysis corrosion or commonly referred to as stray current corrosion. This type of corrosion is caused by stray current from dc sources such as cathodic protection systems, battery charging facilities and sola generation etc. With the increased driving voltages due to the use of external power sources, stray current in the ampere range can cause rapid corrosion by conduction through 3rd party assets that share the common medium of earth or water. Arguably, the most severe form of corrosion is due to stray traction current where corrosion current magnitudes readily reach ten to hundreds of amps.

This webinar outlines the characteristics of electrolysis corrosion with an emphasis on stray traction current effects and management strategies.

STATCOM Solutions for Voltage Management on Distribution Systems
13 June 2019 - Ryan Rainville

This is webinar #4 in a 4-part series presented by AMSC.

SERIES SYNOPSIS

Increased penetration of renewable generation resources (e.g., wind and solar), driven by defined targets for the amount of renewable generation mix, is pushing the performance of today’s transmission grids to new limits in many regions. To ensure a secure and reliable operation of the grid, the Australian utilities and regulators provide direction through their updated interconnection requirements. In this webinar series, reactive power requirements of the new National Electricity Rule (NER) are reviewed for its impact on renewable energy projects.

Meanwhile, on the distribution system, distributed energy sources (DER) in the form of PV solar installations are becoming more prevalent. The existing distribution systems face challenges, including power quality, voltage stability, and reverse power flow.

Solutions that provide secure and reliable power are needed. AMSC is conducting this workshop to increase awareness on the following subjects:

• STATCOM equipment capabilities and model validation required to meet AEMO guidelines
• Renewable energy integration, issues and challenges in Australia
• Voltage collapse/voltage instability, and solutions involving Flexible Alternating Current Transmission Systems (FACTS)
• Reactive power and voltage management using STATCOMs in distribution systems

The workshop will include basic concepts on STATCOMs, renewable energy integration, reactive power compensation, active and reactive power transmission and voltage stability. In-depth analysis of actual voltage stability events along with a discussion on modern methods to prevent such events will be discussed. Attendees will also be able to learn about some of the latest developments in modeling tools and techniques. These techniques will allow power system planners to appropriately identify and address potential problems and ensure compliance of the renewable plants to local codes and requirements.

The workshop is an outstanding opportunity for consultants, engineers and developers who are involved in planning, operation, design, specification, installation and maintenance of transmission and distribution assets, renewable energy or large industrial and mining facilities.

SCADA – EESA’s Fundamentals series
9 May 2019 - Peter Poulos

SYNOPSIS

How well do you know the technology your remote systems and control rooms depend upon?

While perhaps not a flavour of the month like the topical “Internet-of-Things” or “Deep Learning” SCADA (Supervisory Control And Data Acquisition) and related operational technology disciplines are a key enabling infrastructure of many industries.

Technology will continue to evolve rapidly and change some of the ways we provide the remote monitoring and control of assets. The fundamental need to deliver these services in a robust manner is increasing. The exponential growth in telecommunications capacity driven by the internet, mobile computing and the growth of home automation makes it easier and cheaper than ever to remotely control and monitor almost anything.

Just as SCADA practitioners leverage knowledge from other domains, some of lessons the SCADA domain has collectively learnt from over the last 80 odd years might be worth considering.

The talk will cover:

• Origins and fundamental concepts
• Directions and challenges from an electrical distribution network perspective

STATCOM Technology for the Distribution System
October 31, 2018 - Bob McFetridge

SYNOPSIS

STATCOM Technology for the Distribution System, A New Option for Distribution-Connected Renewable Integration and Power Quality Solutions.

The days of large fossil fueled central station power plants are numbered and renewable generation in the forms of wind and solar are quickly taking its place. Wind farms have already spread widely acrossthe world and continue to be installed at a fast pace. PV solar generation is beginning to spread out. While large MW wind farms and PV plants are connected to the transmission system, smaller MW sized wind farms and PV solar plants are connected directly to the distribution system, where infrastructure allows. Certainly, the smaller commercial and residential PV solar installations are connected to the distribution system.

Many utilities impose a step voltage change (or flicker) limit, on their transmission and distribution systems. The value of the limit is usually set at around 2% to 3%. For example, this limit often drives the maximum size of a capacitor bank that can be switched or the rating of the largest line-started induction motor that can be started. . Typically, step voltage changes that are less than 2% are not perceived visually by their customers nor does it usually impact customer processes. Values greater than 2% that occur with greater frequency are known to cause impacts such as customer down-time and excessive wear and tear on utility equipment.

This paper presents methods for designing and sizing STATCOM installations on a utility distribution feeder such that the variation of the renewable generation will not exceed a utility’s step voltage change requirement.
