Hierarchical Distributed Consensus Based Economic Dispatch of Distributed Energy Resources (DERs) for Networked Microgrids

Abstract

Rapid inclusion of distributed energy resources (DERs) has led to the need for a reliable energy management system (EMS) capable of managing these resources effectively at a large scale. This paper proposes a novel hierarchical distributed consensus-based approach for solving the economic dispatch problem in networked microgrids (NMGs). The proposed approach arranges the network in hierarchical structure, thereby reducing the communication requirement between the distributed controllers. Simulation results are presented to demonstrate the effectiveness of the proposed approach. The simulation involves comparing the proposed approach with distributed consensus approach for different network topologies.
