Multi-objective Planning of Distributed Generation in Distribution Network

In the face of energy crises and ecological challenges, connecting distributed power sources in the grid is an effective solution. Therefore, this paper establishes a multi-objective mathematical model for accessing distributed power sources to distribution grids with the objectives of distributed power generation cost, network loss cost, and environmental cost. And the constraints such as branch currents distributed power access capacity, and node voltage in the planning are given. Considering the shortcomings of traditional genetic algorithms in practical application, the genetic algorithm based on vector evaluation is used to solve the planning problem of distributed power supply in distribution networks. Finally, the feasibility of the method proposed in this paper is verified by the IEEE33 node arithmetic example.
