This project is exploring methods by which loads can be aggregated into a grid-friendly network of actively configured, autonomous responses to self-sense frequency and voltage fluctuations, and provide a full range of ancillary services—including virtual inertia, regulation, ramping, spinning reserve, and emergency curtailment capabilities. The specific objectives of this project are to: a) systematically design decentralized frequency-based load control strategies for enhanced stability performance, b) ensure applicability over wide range of operating conditions while accounting for unpredictable end-use behavior and physical device constraints and c) test and validate proposed control strategies using large-scale simulations and field demonstrations.
