Project Description

The Australian power network is undergoing rapid transformation with the inclusion of increasing amounts of inverter-based resources (IBRs), particularly storage and batteries, in the interconnection queue. This may lead to retirement of conventional rotating machine power plants, sometimes before a planned retirement date. While this change in generation resource mix has been shown to deliver secure electricity supply for specific operational snapshots, the ability of the system to retain its stability, security, and reliability over extended periods of time with the occurrence of multiple events, is not known.

To determine the stability of a network with IBRs, both the initial operating point of the network and the controller of the IBR have an important role to play. This proposal aims to develop and improve analytical methods to ascertain the required operating points from IBRs in the bulk power system to operate in a stable and reliable manner. The analytical methods are intended to be scalable to be applied over large areas of the bulk power system. To determine the required operating points from an IBR, this proposal intends to explore the relationship between power system topology, generation resource mix changes and location of resources, availability of reactive power resources, and control behavior of various elements. The proposal aligns well with the high priority tasks identified in the Topic 2 research roadmap document.

The objectives of the proposed project are to enable system planners and operators to determine the operating point of each IBR at a particular location that can subsequently be used to frame up interconnection requirements for the IBR. Additionally, as the operating condition of the network changes, this project aims to provide the planner/operator with the knowledge and methods to analytically evaluate the evolution of stability of the system along with evolution of critical contingencies, with which planning and operating decisions can be made. The evaluation of the stability would be at the various operating points that have been determined.
