| Abstract: | For islanded microgrids, the microgrid system frequency with traditional droop control often deviates from the rated frequency due to the variation of output power. Therefore, a self-adjusting droop coefficient control strategy for microgrids is proposed. Through the consistency algorithm, the micro-power source in the micro-grid obtains the self-adjusting amount of the droop coefficient to achieve no static difference in the frequency of the micro-grid, while ensuring that the active power shares the load according to the rated capacity. A microgrid simulation model is built in PSCAD, and the simulation result verifies the effectiveness of the control strategy through comparison with that of traditional droop control. |
