For the uncertainty of light intensity and load in the photovoltaic(PV)access planning

by using the scenario analysis method and the improved clustering number evaluation index

the number of planning scenarios is reduced while considering the correlation between the loads. Then

surrounding the coordination of distribution companies and photovoltaic operators

a multi-objective bilevel optimal programming model is constructed by considering the effect of reactive power and reactive power on voltage regulation. The upper layer optimizes the PV access capacity

and the lower layer is the voltage regulation strategy for the distribution network with the access of PV. Finally

the evaluation index and the evaluation process of the optimal solution are proposed for the Pareto optimal solution set obtained by using the non-dominated sorting genetic algorithm. The feasibility of the proposed method is verified in the IEEE 33-bus distribution network.
