Abstract

© 2015 IEEE. Microgrids technology is the cornerstone of smart grid, the electricity network of the future. Based on distributed generation, microgrids can contribute to increase the penetration rate of renewable energy resources and hence reduce costs and gas emissions. This paper presents a new design methodology, based on Hamiltonian Surface Shaping and Power Flow Control (HSSPFC), for a decentralized control of isolated microgrids (ImGs) with multiple distributed energy resources (DERs). The local controllers insure the stability of the overall ImG while regulating the voltage at the point of common coupling (PCC) of their respective DERs. Each controller is synthesized independently, using only local information on the corresponding DER, its dedicated load, and the corresponding line. This decentralized control procedure guarantees scalability and plug-and-play (PnP) operations of the ImG.
