Research on distributed energy storage layout planning of distribution network based on simulated annealing particle swarm optimization algorithm

The energy storage system can alleviate the adverse effects of large-scale distributed new energy access to the distribution network, and the rational configuration of the energy storage system is the premise of its effective application. This paper constructs a distributed energy storage layout planning model considering the whole life in the distribution network, and takes the safe and stable operation check after the distributed energy storage is connected to the distribution network as the constraint condition, and adopts the annealing mechanism in the particle swarm optimization algorithm to optimize the solution of the layout planning model, so as to improve the accuracy and convergence speed of the algorithm iteration to find the global optimal solution. Through simulation analysis on IEEE 14 node distribution system, the simulation results show that the algorithm has good convergence and accuracy. This planning method can effectively improve the local consumption level of new energy generation and can be used to guide the planning and layout construction of distributed energy storage in the distribution network.
