摘要：
To realize the stable and optimal operation, a strategy of multi-level power management is proposed for the islanded AC/DC hybrid microgrid cluster. The proposed strategy consists of two parts: distribution control strategy and interaction management strategy of multi-level power. Through the three levels of power autonomy, power interaction and power balance, decentralized management of system power is realized by the distribution control strategy of multi-level power. Considering the two operation cases of normal communication and communication fault, an interaction management strategy of multi-level power is proposed for AC/DC hybrid microgrid cluster, which can realize reasonable switching management between power distribution levels. Meanwhile, the proposed strategy can ensure the power quality of the islanded system, and reduce interaction loss of system power. To lower the system requirements for the communication network, the event-triggered controller is designed to realize data exchange only at the moment of the event triggering. Finally, the effectiveness of the proposed control strategy is verified by MATLAB/Simulink simulation platform. © 2020 Automation of Electric Power Systems Press.
