Abstract

Abstract

In order to achieve the flexible operation of microgrids, distributed cooperative control is always implemented to manage the distributed renewable energy resources within microgrids due to its better flexibility reliability and scalability. However, the time-triggered traditional distributed control strategies lead to a great waste of the communication resources of distributed generators’ local controller, and hence reduce the efficiency of microgrids’ operation. To this end, a distributed event-triggered control-based frequency secondary control method in microgrids under directed communication network is proposed. By designing an event-triggered mechanism for the active power sharing control under directed communication network and designing a local controller for the frequency restoration control, the secondary control of islanded microgrids can be achieved with greatly reduced communication resources. It is demonstrated by the theoretical analysis that the designed control method does not exist Zeno behavior. The simulation results show the effectiveness and superiority of the proposed control method.
