摘要：Distributed generators with high permeability cause voltage quality problems such as voltage deviation and fluctuation, and increase network loss as well. Aiming at this problem and taking configuration of energy storage as a solution, the optimal allocation strategy of energy storage location and capacity of distribution network is put forward combined with the power four-quadrant output control strategy of the battery energy storage system, which aims at improving the economic benefit and voltage quality of the distribution network. Specifically, an economic operation model for distribution network with the goal of minimizing the sum of purchase cost, network loss cost and investment cost is constructed. The time scale is set as 15 min for rolling calculation, and the lowest total cost in a typical day is used to choose the siting and sizing of storage. Meanwhile, the migration and fluctuation range of each node voltage is constrained, and the mixed integer second-order cone mathematical programming is used to optimize the solution. The simulation results of IEEE 33-bus distribution network demonstrate the feasibility and efficiency of the proposed optimal configuration method. © 2020 Automation of Electric Power Systems Press.
