Under the background of the transformation of distribution network to low-carbon

the high proportion of green energy and electric vehicles powered by electric energy are developing continuously

and the operation and planning of distribution network are facing new challenges and opportunities. Based on this

an optimal planning model of distribution network including electric vehicle charging load and distributed photovoltaic is proposed. First

the electric vehicle charging load and distributed photovoltaic timing characteristics are modeled. Second

considering the economy

low carbon and stability of the distribution network

a multi-objective planning model is constructed with the annual comprehensive benefit

carbon emission and load variance of the distribution company as the objective function

and the multi-objective coati algorithm is used to solve the above model

and the global Pareto optimal solution set is retained based on the Pareto dominant principle. The equilibrium decision function is introduced to evaluate the distribution equilibrium of the optimal solution.Finally

the feasibility of the proposed model and method is verified by an example analysis on IEEE-33 node power distribution system.
