Hierarchical management and control based on MAS for distribution grid via intelligent mode switching

Abstract

Due to an increased penetration of distributed energy resources, as well as more uncertain operating environment, etc., present distribution power system is facing many challenges. For improving the performance regarding dynamic stability, self-healing, security, as well as economical and environmental benefit, this paper proposes a hierarchical management and control strategy for the high-penetrated distribution grid based on multi-agent systems structure via intelligent switching of operating mode. Corresponding to the complex hybrid behaviors, the hierarchical control scheme is designed as a three-level decentralized coordinated hybrid control. The simulation studies certify that the hierarchical hybrid control is effective and feasible to deal with comprehensive problems of high-penetrated distribution grids.
