Optimization Planning of Incremental Distribution Network Considering Multi-agent Benefits

Aiming at the optimization planning problem after the incorporation of distributed power sources in the incremental distribution network, the optimal plan that takes multi-agent benefits into account is proposed to realize the coordination and optimization of multiple market agents. First, the planning and decision-making models of distributed generation(DG) operators, distribution network investment companies, and power customers are constructed respectively. Then, considering the uncertainty of introducing distributed generation to distribution network, a multi-agent programming model is constructed based on the relationship of three market agents. Finally, the second-order conic relaxation is combined to deal with the power flow constraints, and Cplex is used to solve the above model. It can be seen from the simulation results that the proposed incremental distribution network optimization planning can realize the reasonable income of each market agent and optimize the overall income.
