摘要/Abstract

摘要： 微电网孤岛运行时，采用传统下垂控制策略的微电网频率因其输出功率的变化而偏离额定值，为此，提出一种微电网下垂系数自调节控制策略。微网内各微源由一致性算法获得下垂系数自调节值，实现微电网频率无静差，同时确保有功功率按额定容量分担负荷，在PSCAD中搭建微网模型，并与传统下垂控制仿真结果对比，表明了控制策略的有效性。

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.
