“Power system operation with high-share of grid-connected and distributed inverter-based resources”

Topic 1: Power system modelling: present and moving forward

This presentation will provide a brief overview of the inherent modelling differences between synchronous generation and asynchronous generation, how wide-area EMT models are increasingly required to provide a realistic representation of power system dynamics in a grid dominated by inverter-based resources, and how traditional RMS models are proving to be inadequate or overly optimistic when performing transient stability studies. Limitations of both RMS and EMT models will be discussed, along with an overview of the initiatives currently taking place to address the new challenges posed by the adoption of EMT models for transient stability analysis, and the perspective of international Independent System Operators on the issue.

Topic 2: New and emerging bulk power system security challenges

The generation mix across the National Electricity Market (NEM) of Australia is changing rapidly over the last few years. This increases the complexity of operating one of the longest power systems of the world and present unprecedented operational challenges due to increased penetration of inverter-based resources (IBR). Large update in transmission and distribution connected IBR often results into early retirement or mothballing of traditional synchronous generators which provide some of the system security services such as inertia, contribution to system strength, voltage and frequency control. With change in generation mix these services are required to be sourced from new technologies. The majority of IBR in the NEM are located in remote areas of the grid, typically far from load centres and conventional synchronous generators. Being in remote and weak part of the network a small reduction in system strength either during a planned or forced outage of a network element could manifest into system security issues.
This presentation will discuss some of the technical challenges associated with integrating large amount of IBR into relatively weak part of the network. The presentation will show real life example of emerging bulk power system security challenges and some of the solutions to address them.

Topic 3: New and emerging power system security challenges caused by distributed energy resources

Distributed PV is growing rapidly in the National Electricity Market (NEM), and minimum demand levels are reducing. South Australia is forecast to reach zero megawatts of operational demand in the next year or two, with enough distributed PV operating to meet the entire demand of the region. What will this mean for the operation of the power system? What measures need to be put in place to ensure we can continue to operate a secure and reliable power system? This presentation will cover AEMO’s investigations into power system operation in periods with low demand and high levels of distributed PV, discussing emerging power system security challenges such as distributed PV disconnection in response to transmission faults, the need for distributed PV curtailment capabilities to be able to maintain minimum levels of synchronous generating units online for system strength and inertia, and impacts on under frequency load shedding schemes.

Topic 4: System restoration: present and moving forward

This session will cover how AEMO prepares and implements restoration of the power system when a wide-scale blackout occurs in the NEM, including:

  • The challenges associated with recovering from wide-scale blackouts.
  • What AEMO currently has in place to assist with NEM system restoration, which needs to be in place well in advance of any blackout event.
  • How AEMO is adapting system restoration to changes in the power system and generation mix.

“Solar PV integration challenges and opportunities”


Recently, utility-scale photovoltaic (PV) plants in remote areas are drastically increasing due to abundant and low-priced land. These remote areas are usually connected to zone substations through long weak feeders with open-delta step voltage regulators (SVRs) to regulate downstream voltages. However, distribution grids in such areas traditionally have feeders with low X/R ratios, which makes the independent reactive power compensation method less effective on voltage regulation. Consequently, upstream SVR may suffer from excessive tap operations with PV-induced fast voltage fluctuations. Although a battery energy storage system (BESS) can successfully smooth PV generation, frequent charge/discharge will substantially affect its cost effectiveness. In this tutorial, these solar PV integration challenges will be addressed and corresponding solutions will be discussed. This tutorial will provide valuable insights and applicable strategies to both utilities and PV owners for large-scale solar PV integration into distribution networks.

“DER Flexibility”


The aim of this tutorial is to present the main techno-economic concepts about provision of power system flexibility, reliability and resilience from distributed energy resources (DER).
Specific topics that will be covered include:

  • Modelling of DER for flexibility study purposes, including different types of distributed/embedded generators (e.g., photovoltaic, gas, diesel, and combined heat and power generators), storage (e.g., batteries, electric vehicles, thermal storage), and demand response (e.g., smart appliances, building-to-grid flexibility, hydrogen electrolyzers) resources;
  • DER aggregation modelling and orchestration under different concepts such as power nodes, virtual power plants, community energy systems, and microgrids;
  • Techno-economic characterization of the flexibility of individual DER and DER aggregations, with consideration of different metrics;
  • Generalization of DER to the emerging concept of distributed multi-energy systems (which also entail interaction with other energy vectors such as heat, cooling, hydrogen, etc.) and modelling of multi-energy flexibility via the recently proposed concept of multi-energy node;
  • Use of DER flexibility to provide market, security and reliability services, to support both system operation (e.g., energy arbitrage, frequency control ancillary services, fast frequency response, reactive power and voltage support) and planning (e.g., DER contribution to supply and network adequacy and capacity markets, displacement of network asset, firm-up of renewables and capacity credit assessment);
  • Use of DER flexibility to provide resilience services to deal with extreme, high-impact low-probability, events (again for both operation and planning);
  • Modelling and assessment of DER in the interaction with distribution system operators and at the interface with transmission system operation;
  • Discussion of technical, commercial and regulatory barriers to DER widespread adoption;
  • Case studies from a number of recent projects in Australia, UK, Europe, Malaysia and Chile.

A full list of relevant references and toolboxes will also be provided.

“Using scenarios to explore potential futures for our energy systems”


This tutorial will explore the use of scenarios as a tool to better appreciate the potential range of futures that our energy systems may face. It will look into the benefits of scenario-based planning, and also recognise some of the challenges that it can present. Examples of scenarios and scenario development approaches will be shared to help the attendees understand the practical applications of this in real world situations. Having been introduced to the concepts of scenario development the tutorial will end in a workshop-style session where the participants will collaboratively develop a range of scenarios according to a range of possible dimensions before thinking about the likely consequences of those scenarios – and the implications of using those scenarios to understand the future energy system.

A passion for data driven decision making and being at the edge of new technology has driven Cameron’s career. Cameron has championed risk-driven analysis of renewable energy, power stem integration studies, and research and product development related to wind and solar energy modelling for commercial and/or government purposes.
