Abstract

The distribution network station area with strong intermittent distributed photovoltaic large-scale access has such features as wide range of points

dispersion and disorder

which makes it difficult to select the location of the access scheme. To this end

a robust optimization planning model for large-scale distributed photovoltaic access to distribution networks is proposed with consideration of the ability of the distribution network station area to accept distributed photovoltaics. Firstly

the topology analysis method of the distributed photovoltaic access distribution network station area is designed and the planning model of distributed photovoltaic access distribution network with minimum cost as target is constructed.Secondly

the robust optimization method is applied to deal with the uncertainty of distributed photovoltaic output and genetic algorithm（GA）is used to solve the planning model so that the optimal access point and optimal installation capacity of distributed photovoltaic can be obtained in a single solution. Finally

the effectiveness of the proposed model in improving power quality and model optimization speed is verified by the case of IEEE 33-node distribution network.
