In order to solve the problem of voltage deviation caused by distributed photovoltaic high density multi-point access to distribution network,based on the analysis of the impact of distributed photovoltaic access to low-voltage distribution network,an optimal location model for distributed photovoltaic multi-point access, to low-voltage distribution network is established,and an optimization model solution method and process is proposed based on genetic algorithm.Aiming at a typical case,the location and distribution of the proposed distributed photovoltaic project are simulated and analyzed.The results show that this method can effectively calculate the location and distribution of photovoltaic.The distribution of photovoltaic in low-voltage distribution network tends to be in the middle and end of distribution line,which can provide reference for the planning and design of distributed photovoltaic access to low-voltage distribution network.
