Distributed Economic Dispatch for Active Distribution Networks with Virtual Power Plants

With the growing penetration of distributed energy resources (DERs) such as renewable energy generators, battery storages and controllable loads, virtual power plant (VPP) has become the promising solution for flexible energy management in active distribution networks (ADNs). This paper presents an alternating direction method of multipliers (ADMM)-based distributed economic dispatch (ED) strategy for ADNs with multiple VPPs. The proposed scheme is suitable for three-phase unbalanced system considering network constraints. Each VPP exchanges limited boundary information with distribution system operator (DSO) protecting data privacy. Numerical tests validate the effectiveness of the proposed method.
