摘　　要：利用柔性多状态开关(soft open point,SOP)提升配电网的分布式能源(distributed generation,DG)消纳能力,提出了配电台区SOP的多目标优化控制策略。通过分析配电网SOP的接入模式,考虑其在分布式电源消纳与削峰填谷的作用,构建了分布式能源日消纳量最大、控制成本最低和馈线日净负荷偏差最小的多目标模型。以改进的配电网算例进行仿真对比验证。结果表明:SOP接入有利于提升新能源消纳,并实现负载均衡。A multi-objective optimization control strategy for distribution station SOP is proposed to enhance the distributed generation(DG)consumption capability of the distribution network by utilizing multi soft open point(SOP).By analyzing the access mode of SOP in the distribution network and considering its role in distributed power consumption and peak shaving,a multi-objective model was constructed to maximize the daily consumption of distributed energy,minimize control costs,and minimize the deviation of daily net load of feeder lines.Conduct simulation comparison and verification using an improved distribution network example.The results indicate that SOP integration is beneficial for improving the consumption of new energy and achieving load balancing.
