摘　　要：探究基于柔性多状态开关的分布式能源消纳控制技术,并对比传统的下垂控制策略与改进的模糊下垂控制策略在分布式能源消纳方面的应用效果。基于模糊控制理论构建柔性多状态开关消纳控制结构,以直流电压、功率裕度作为输入量,以下垂系数作为输出量,并构建三者的模糊集和模糊逻辑推理表。利用Z形隶属度函数的计算结果调节下垂系数,达到实时优化效果。从仿真应用情况来看,当直流负荷增加时,改进的模糊下垂控制策略具有下垂系数变化小、电压波动不明显,以及稳态直流电压更加接近标准电压等优势,实现电压恒定与功率分配精度的兼顾。This paper explores the distributed energy consumption control technology based on flexible multi state switches,and compares the application effects of traditional droop control strategy and improved fuzzy droop control strategy in distributed energy consumption.A flexible multi state switch consumption control structure was constructed based on fuzzy control theory,with DC voltage and power margin as input variables and sag coefficient as output variables.Fuzzy sets and fuzzy logic inference tables were constructed for the three variables.Adjust the droop coefficient using the calculation results of the Z-shaped membership function to achieve real-time optimization.From the perspective of simulation applications,when the DC load increases,the improved fuzzy droop control strategy has the advantages of small changes in droop coefficient,less obvious voltage fluctuations,and a steady-state DC voltage closer to the standard voltage,achieving a balance between constant voltage and power distribution accuracy.
