摘要
为避免配电网网架出现明显的动态变化行为,从而实现对电量指标的准确识别,提出基于负荷组合预测的配电网网架动态变化识别方法。利用逆变器控制结构,分析网架变化行为的表现能力,再联合已知的动态电量匹配系数,完成对配电网网架的动态变化特性研究。在此基础上,选取关键电量负荷指标,通过建立等权组合条件的方式,得到符合应用标准的电量预测结果,实现基于负荷组合预测的配电网网架动态变化识别方法的设计与应用。对比实验结果表明,与改进卷积神经网络的评估方法相比,在负荷组合预测标准的作用下,配电网网架的动态变化行为能力得到了有效抑制,符合准确识别电量指标的实际应用需求。
In order to avoid obvious dynamic change behavior of distribution network frame and realize accurate identification of electric quantity index,a dynamic change identification method of distribution network frame based on load combination prediction is proposed.By using the control structure of inverter,the performance ability of grid changing behavior is analyzed,and then combined with the known dynamic electric quantity matching coefficient,the dynamic change characteristics of distribution network grid is studied.On this basis,the key quantity load index is selected,and the quantity prediction results in line with the application standard are obtained by establishing equal weight combination conditions,so as to realize the design and application of the identification method of dynamic change of distribution network frame based on load combination prediction.The comparative experimental results show that,compared with the improved convolution neural network evaluation method,under the action of load combination prediction standard,the dynamic change behavior ability of distribution network frame is effectively restrained,which meets the practical application requirements of accurately identifying power indicators.
