| Summary: | To further improve energy utilization efficiency, a regional energy interconnection micro-grid structure with independent operation is proposed. In micro-grid, output voltage deviation of distributed generations is caused by inconsistent impedance of alternating current line. An algorithm of distributed average voltage consistency is used to improve the accuracy of reactive power distribution. It can distribute reactive power according to the ratio of distributed generation capacity by secondary adjusting the droop control voltage of the grid-connected inverter, so as to ensure the same output voltage of each distributed generation. Compared with centralized control, distributed control does not use a central controller, which can improve the coordination and reliability of the system. A simulation model was established using Matlab/Simulink, and the operation performance of the energy interconnection micro-grid was simulated and verified, which proved the effectiveness of the distributed control strategy. |
