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.
