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

•A MAS based management and control strategy for distribution grid is researched.•A three-level hierarchical decentralized coordinated hybrid control is designed.•The energy management strategies are drafted based on CPN.•The discrete coordinated control strategies are drafted for real-time operating mode reconfiguration.•The simulation studies testify the effectiveness of the proposed control.

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.
