Power system flexibility refers to the technical, economic, and institutional capabilities that allow electricity systems to accommodate variable renewable generation and dynamic demand while maintaining reliability. Work in this area develops control strategies for distributed energy resources, flexible electric vehicle charging, and building loads, alongside grid-forming converters, storage integration, and virtual batteries. It also encompasses local and wholesale market designs, policy and governance frameworks, and AI-based forecasting and optimization tools that coordinate flexible assets to enhance resilience, reduce grid reinforcement needs, and support decarbonization goals.
