考虑安全约束的交直流配电网储能与换流站协调经济调度
Security-constrained Coordinated Economic Dispatch of Energy Storage Systems and Converter Stations for AC/DC Distribution Networks
摘要
Abstract
With the rapid development of DC distribution technology, distributed generation (DG) and energy storage system (ESS) can be integrated with distribution networks more efficiently, and a hybrid AC/DC topology configuration may appear.This paper presents the security-constrained coordinated economical dispatch method of energy storage systems and converter stations for hybrid AC/DC distribution networks.By optimizing reactive power adjustment of the converter station and charging/discharging of ESS, power supply companies can ensure safe operation of distribution networks while minimizing the total cost of energy purchased from the upper grid on the transmission and distribution separated electricity market.In addition, this is a mixed integer nonlinear programming problem and is difficult to solve.In this paper, the original model is transformed into a mixed integer linear programming problem by linearization technique.Finally, the simulation results can demonstrate the effectiveness and rapidity of the proposed method.关键词
