摘　　要：对光伏发电功率的稳定性进行控制可以保证变电站的稳定运行,为了提高光伏发电功率稳定性的控制精度,提出了变电站光伏发电功率稳定性控制方法。通过对光伏发电功率数据的标准化处理,结合变电站的天气状况,预测变电站的光伏发电功率。在不同模式下,通过计算直流侧子网的负载需要、光伏发电设备处于稳定状态的功率、直流侧子网的功率以及冗余功率,实现光伏发电功率的稳定性控制。实例分析结果表明,所提方法能够有效控制光伏发电功率,并提高控制精度。Controlling the stability of photovoltaic power generation can ensure the stable operation of substation.In order to improve the stability control accuracy of photovoltaic power generation,a research on the stability control method of photovoltaic power generation in substation is proposed.Through the standardization of photovoltaic power data,combined with the weather conditions of substation,the photovoltaic power of substation is predicted.In different modes,the stability control of photovoltaic power generation is realized by calculating the load demand of DC side subnet,the power of photovoltaic power generation equipment in stable state,the power of DC side subnet and redundant power.The example analysis results show that the proposed method can effectively control the photovoltaic power generation and improve the control accuracy.
