Abstract
The complex form of power supply results in varying distributed photovoltaic capacity and limited absorption capacity for each node,which seriously affects the reliable utilization of photovoltaic power in the distribution network system.Aimed at the issue,a distributed photovoltaic absorption capacity optimization model for distribution network based on line loss sensitivi-ty factor and interval power flow is proposed.The raw data of the distribution network is classified by the line loss sensitivity factor,and the maximum load loss in the interval is calculated using the root mean square current method to obtain the true op-erating line loss data of the distroution network.This paper sets interval power flow constraints,simulates the operation status of the distribution network with equivalent circuits,and matches the distribution form of photovoltaic nodes.The access vol-ume of each node is summarized by an objective function,the economic benefits of the distribution network is comprehensively considered,and an optimization model is constructed by a weighted processing function.The experimental results show that af-ter the application of the model in this article,the phenomenon of abandoned light can be reduced,the nighttime electricity load can be ensured,and the optimization of consumption is basically consistent with the predicted values.It can change the energy storage mode of the photovoltaic system,improve the problem of abandoned light in the distribution system,and has practical effects.关键词
