| 摘 要： | 在微网系统中,大功率电力负荷的投切会导致电网电压幅值和频率产生波动.将储能装置应用于微网系统中,可通过逆变控制单元,实时监控电网电压波动,即时调节配电网输送的有功无功功率大小,从而达到抑制电网电压波动的效果.采用了电压频率环控制和有功、无功补偿控制相结合的控制算法,可以即时检测电网电压波动并进行快速补偿,具有较强的有功、无功调节能力.最后通过构建模拟微网环境,进行了不加储能装置和接入储能装置后微电网投入不同电力负荷时电压波动对比实验,验证了控制策略的有效性和正确性.

| Abstract: | In micro-grid,the amplitude and frequency of output voltage will fluctuate with the switching of large-power electric load.With inverter control of energy storage system,both active and reactive power pumped into the utility grid can be controlled which could achieve the stabilizing effect of voltage fluctuations.The proposed approach combines voltage and frequency dual-loop control with active and reactive power control which can real-time detect and compensate the voltage fluctuation.The experimental results demonstrate the effectiveness of the proposed control strategy. |
