Abstract: The number of power electronics converters connected to electrical networks has been growing exponentially as they are part of all new generation connected to the grid. While the rapid control and fast electronic switching available with this technology offer flexibility in network operation, the dynamic interactions between several of them threaten the operational stability of the transmission grid is a concern. It is required to develop a methodology for identifying the risks associated with the stability and control interaction before a new power electronic device (e.g. Windfarm, interconnector, STATCOM) is introduced to the network The talk will focus on an analytical framework in impedance domain to quantify the interaction between the new plant and the rest of the network for setting additional grid connection study specifications which will include detail technical study to check and mitigate the risks associated with new power electronics interfaced generation. The framework developed is to support MMC technology, control delay, system strength and FRT capability of dynamic voltage support devices and windfarm through technical case study conducted at the research group of Bikash Pal at Imperial College London. Future research challenges and opportunities will be highlighted.

Abstract: As the penetration of variable renewable generation increases in power systems, issues such as grid stiffness, larger frequency deviations, and grid stability are becoming more relevant. In this context, Energy Storage Systems (ESSs) are proving to be effective in facilitating the integration of renewable resources, and thus are being widely deployed in both microgrids and large power grids. This talk will review several energy storage technologies, particularly Compress Air Energy Storage (CAES), flywheels, batteries, and thermal energy systems, and their modeling and applications for power systems. An overview will be provided of the work being carried out by Prof. Canizares' group at the University of Waterloo on all these energy storage systems, focusing on novel models and applications in microgrids and distribution and transmission grids for system stability and control, in particular for frequency regulation.

Abstract: With the rapid increase of renewable energy integration, power system dispatch and control are facing challenges to maintain the frequency security and stability requirements because of the volatile, randomness and low-inertia characteristics of the renewable generations. Traditional, for the classical power system dispatch problems, e.g. unit commitment and economic dispatch, the frequency security and stability constraints are not considered. And, only the traditional generators are considered for frequency control resources. However, with the increase of power fluctuation and reduce of inertia in modern power systems, more and more researchers are considering frequency security constraints in the dispatch problems. And new control resources and strategies are proposed for frequency regulation to maintain both frequency control performance and frequency security of the evolving power system. This presentation will cover the primary, secondary and tertiary frequency control problems. Framework and basic principles of these frequency control problems will be briefly reviewed first. For tertiary frequency control, the unit commitment and economic dispatch problems considering the frequency security constraints will be discussed. The emphasize will be on the methods to deal with linearization of nonlinear frequency security constraints. The economic dispatch method considering the secondary frequency control cost will be also introduced. For the secondary frequency control problem, the stability analysis of load frequency control systems with multiple delays will be explained. Then a reinforcement learning based coordinated but differentiated load frequency control method considering multi-type frequency regulation resources will be introduced and simulation results will be shown. Making use of the flexibility of the inverter-Based Resources, the idea of setting the primary frequency control parameters dynamically to ensure frequency stability will be explained. Finally, the future research directions will be discussed.
