摘要

直流配电网技术的发展，为分布式电源、储能的接入提供了更高效的方式，同时也使配电网呈现出交直流混合的拓扑形态。提出了基于安全约束的交直流混合配电网储能与换流站协调经济调度方法，通过优化换流站的无功调节与储能的充放电，一方面能确保配电系统安全运行，另一方面在输配分离的电力市场环境下可最小化供电公司从上级电网购电的成本。另外，交直流混合配电网经济调度模型属于混合整数非线性规划，缺乏快速有效的求解方法，通过线性化技术将原模型转化为能有效求解的混合整数线性规划问题。最后，通过算例测试验证了所提方法的效果及求解的快速性。

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.
