摘要
可再生能源渗透率较高的孤立微电网中,储能系统作为备用电源,其控制对系统电压和频率的稳定性有着重要的影响。建立了包括储能模型在内的微电网数学模型,综合考虑储能状态及逆变器控制参数对系统的影响,深入研究分析了控制器参数影响系统稳定性的规律,最后通过仿真实验验证了结果的正确性。
The control of energy storage system has important influence on the stability of the voltage and frequency of the isolated micro-grid system. In this paper, a small-signal model of micro-grid is established, especially including energy storage model.Based on the existing small signal analysis, the influence of the energy storage state and the control parameters of the inverter on the stability of islanded micro-grid is analyzed, and the rule of those influences is summarized. The simulation results show that the system has strong adaptability to load mutation and energy storage state fluctuation with controller parameters determined according to the rule.
