Internationally the power grid is undergoing a transformational change. The legacy grid which was centrally controlled and consisted of largely ac generators, transmission lines and dispatchable energy sources is being replaced by a flexible de-regulated grid with increasing renewable energy sources, HVDC converters and smart controls. These changes are challenging the capabilities of simulation and modelling tools. The lecture will give an overview of the new requirements that are necessary, particularly for electromagnetic transient simulation tools resulting from the changing grid structure. One challenge is how to simulate large power electronic converters such as Multi-level modular converters (MMC) that have a very large component count. Methods to model very large systems and optimization approaches to select parameter gains for the controllers of converters in an HVDC grid that will result in robust operation will be presented New study methods that combine multiple simulation tools on the same computing platform will also be presented. Emerging simulation platforms such as real-time simulators and hybrid simulators will be discussed
Prof. Ani Gole is Distinguished Professor and NSERC Industrial Chair in Power Systems Simulation at the Department of Electrical and Computer Engineering, at the University of Manitoba. He has over 30 years’ experience in the development of modelling tools for power networks incorporating power-electronic equipment such as HVDC and FACTS converters. He is one of the original developers of the widely used PSCAD/ EMTDC simulation program. Dr. Gole has also made important contributions to the development of the real-time digital simulator RTDS from RTDS Technologies of Winnipeg, Canada. Dr. Gole is a Registered Professional Engineer in the Province of Manitoba, Canada. He is a Fellow of the Canadian Academy of Engineering and an IEEE Fellow. For his contributions to the modelling of Flexible Ac Transmission System (FACTS) devices, he received the IEEE Nari Hingorani FACTS medal in 2007. Currently Dr. Gole serves on the Long Range Planning Committee of the IEEE Power and Energy Society, and on the IEEE PES Fellows Panel.
