Research on Voltage Unbalance Equilibrium Cooperative Control Method for Distributed Power Generation

Abstract

The unbalanced grid voltage will cause the interface device inverters to fail to work effectively. In this paper, a notch filter which can eliminate fixed frequency is introduced on the basis of modeling and analysis of distributed generation interface device, and it is combined with voltage compensation controller. Finally, a model is built in Matlab/simulink to verify the simulation results. The results show that the unbalanced balanced cooperative control method proposed in this paper can effectively play a balanced control role in the system. Finally, the model is built in Matlab/simulink for simulation verification. The results show that the unbalance equilibrium cooperative control method proposed in this paper can effectively control the system.
