Research on the combined control method for parallel inverters control of micro-grid

Traditional parallel inverters control methods, i.e. the master-slave control and peer to peer control method cannot meet the demand of control of micro-grid because of their shortcomings. The Combined Control Method for Parallel Inverters Control of Micro-grid has been proposed in this paper, which includes PQ control and active power-voltage control combined with droop control scheme. Then, voltage source inverter control model of micro-grid is built based on MATLAB/SIMULINK platform. Simulation results show that droop control scheme works well in this combined control method.
