考虑光储协调的配电网多阶段电压控制方法研究

Research on Multi-Stage Voltage Control Method for Distribution Network Considering Photovoltaic Energy Storage Coordination

常规的配电网多阶段电压控制方法主要使用Kantorovich拉丁超立方距离削减抽样算法构建控制求解模型,易受源-荷随机波动场景变化的影响,导致控制电压幅值与实际电压幅值偏差过高。因此,提出了一种考虑光储协调的配电网多阶段电压控制方法,即构建配电网多阶段电压控制模型,考虑光储协调生成配电网多阶段电压控制策略,从而实现配电网多阶段电压控制。结果表明,设计的配电网多阶段电压光储协调控制方法的控制电压幅值与实际电压幅值拟合,偏差较小,具有可靠性及一定的应用价值,为提高配电网综合运行性能作出了一定贡献。

The conventional multi-stage voltage control method for distribution networks mainly uses Kantorovich Latin hypercube distance reduction sampling algorithm to construct a control solution model,which is susceptible to the influence of source load random fluctuation scenarios,resulting in excessive deviation between the control voltage amplitude and the actual voltage amplitude.Therefore,a multi-stage voltage control method for distribution networks considering photovoltaic energy storage coordination is proposed,which constructs a multi-stage voltage control model for distribution networks,considers photovoltaic energy storage coordination to generate multi-stage voltage control strategies for distribution networks,and thus achieves multi-stage voltage control for distribution networks.The results show that the multi-stage voltage photovoltaic energy storage coordinated control method designed for the distribution network has a small deviation between the control voltage amplitude and the actual voltage amplitude,and has reliability and certain application value,making a certain contribution to improving the comprehensive operational performance of the distribution network.
