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

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.
