Abstract:Microgrid is one of the most effective means to manage and control the distributed generation flexibly. Compared to the traditional central secondary control for voltage, the distributed cooperative way is more flexible and reliable. A secondary voltage control in an islanded microgrid based on multi-agent system is proposed. The distributed generation is represented by the agent, and consequently the researched target is converted to a synchronization problem. The distributed controller is designed based on linear states feedback, in which the actual states are replaced by outputs of the estimators and the event-triggered controllers are used to update the estimators. Each of the agents restores the voltages of the islanded microgrid to the normal value in a cooperative way using a communication network without central controller. Inter agent communication is only activated when events are triggered. Thus inter-agent communication is reduced and the requirement to the communication network is lowered. The effectiveness of the proposed control strategy is verified using an islanded microgrid test system.
