Distributed control of thermostatically controlled load aggregators in multi‐area power systems

Abstract In modern power systems, the high penetration of renewable energy challenges system frequency regulation and stability. In such conditions, the demand‐side loads can be aggregated and applied for power system frequency regulation. In this study, a dual‐level distributed control framework is...
