摘要：
In order to monitor an AC / DC hybrid microgrid in real time and choose the appropriate control and management methods to ensure the reliability, security and economy of the microgrid power supply, an AC/DC hybrid microgrid monitoring system based on multi-agent is designed and a layered control strategy is proposed. The system uses sensors to collect environmental information and electrical information, and divides the AC/DC hybrid microgrid into equipment layer, microgrid layer and distribution layer for hierarchical control and management. Each agent in the equipment layer adopts adaptive control to ensure work reliability; the distribution layer adopts centralized control to optimize the system globally to ensure power supply economy; the micro network layer adopts centralized/master-slave hybrid control to make the agents coordinate with each other to ensure power supply stability and safety. The experimental platform is used to test the information monitoring and operation of the designed monitoring system, and MATLAB/Simulink is used to simulate various working conditions of the proposed hierarchical control strategy. The experimental results show that the sensors work stably, the signal distortion is small, and the system runs reliably. The simulation results show that the layered control strategy can effectively reduce the power grid fluctuation under various working conditions, and achieve the design purpose. © 2020, High Voltage Engineering Editorial Department of CEPRI.
