Abstract
This study addresses the overvoltage issues that occur during the peak output period at noon due to power flow reversal after a significant number of distributed photovoltaic(PV)systems are integrated into the distribution network.It proposes an overvoltage protection strategy based on cluster division and the Shapley value method for responsibility allocation of overvoltage.The approach commences with the segmentation of the distribution network into clusters using the modularity index.Then,by leveraging the power transmission distribution factor and the voltage sensi-tivity matrix,this study evaluates the influence of each distributed PV entity on the line power flow and node voltage.Utilizing the Shapley value method,it apportions the curtailment of grid-feeding power among each distributed PV entity proportionally to their impact,ensuring system voltage is maintained within normal parameters.Based on the improved IEEE33 system as a case study,the findings demonstrate that the proposed model effectively distributes the power reduc-tion burden equitably among the distributed PV entities while minimizing the total system-wide power reduction and line losses throughout the distribution network.关键词
