Distributed cooperative control for multiple photovoltaic generators in distribution power system under event-triggered mechanism

This paper investigates the distributed event-triggered cooperative control for multiple photovoltaic (PV) generators in distribution power system. Considering the issue of limited bandwidth of communication network in practical application, two types of novel distributed event-triggered mechanism are introduced to reduce the information transmission pressure, and the distributed cooperative controllers are designed for PV generators based on the proposed triggering schemes. Under the control strategy, the fair utilization of all PV generators is realized, and the active power flow across certain transmission line and the voltage of critical bus can be restored. Simulation results show the effectiveness of the proposed method.
