Research on Joint Optimal Planning Method of Distribution Network Considering Different Operators Participation

Aiming at the optimal configuration of distributed generations (DGs) and microgrids (MGs) of different operators in the distribution network (DN), this paper proposes a multiobjective joint optimal planning method that takes the benefits of DN-DGs-MGs into account. The operating principle of the distribution network aiming at the economics and power quality of the system and the economic benefits of DG operators and MG operators are used to build the joint optimization model. The installed capacities and access locations of distributed generations, and the interaction powers and configurations of microgrids are selected as the decision variables. A mathematical programming solver (Gurobi) combined with non-dominated sorting genetic algorithm II (NSGA-II) is used to solve the joint optimization model. The effectiveness of the model and algorithm are verified in 33-bus system, and it is proved that a reasonable configuration through the joint optimization model can achieve the benefits of different operators and provide a reference for practical engineering applications.
