Study on Optimal Allocation of Distribution Network with Distributed Power Supply and Energy Storage System
For a large number of distributed power generation and energy storage systems connected to the power grid,in order to effectively configure the distribution network system and realize its optimal economic operation,the optimal configuration method of battery energy storage system and distributed generators in the distribution system was proposed,and a mixed integer nonlinear programming model was established and solved by the planning-operation decomposition method.A simulated annealing algorithm that defines the neighborhood structure was adopted,and a decomposition method was put forward to solve the operation state problem of the energy storage system,so as to ensure the near-global optimal solution with low computational cost.Finally,the proposed planning-operation decomposition method was tested on a medium-voltage distribution system with 230 nodes and the planning-operation method is used for configuration.The results show that if the energy storage system and distributed generation are connected at the same time and properly configured,the benefits will be high.Although the cost will also increase,it will have long-term benefits.At the same time,the effectiveness and feasibility of the configuration method are verified.
