摘要

针对高比例分布式电源接入下有源配电网产生的新能源消纳、馈线功率急剧波动、倒送和越限等问题,提出一种基于旋转潮流控制器柔性互联的有源配电网储能系统双层优化配置方法。首先,构建双层模型,规划层模型以全寿命周期内旋转潮流控制器（RPFC）和储能配置下系统回收期为优化目标,实现RPFC和储能位置与容量的最优配置,运行层模型以配电网年运行成本为优化目标,引入RPFC将柔性互联作为灵活性调节资源参与运行优化。其次,采用Pulp求解器与遗传算法混合优化求解储能优化配置模型。最后,通过IEEE 33节点算例进行仿真,结果验证所提RPFC和储能联合配置方案在配有柔性互联装置的配电网中具有适用性,能有效改善弃风弃光、馈线功率倒送和越限等问题,提高新能源消纳率、系统的灵活性和经济性。

Abstract

Aiming at the problems of wind and solar curtailment, reverse transmission and over-limit of feeder power caused by the access of distributed generation in high-penetration active distribution network, this paper proposes a bi-level optimal configuration method of energy storage system based on flexible interconnection of rotating power flow controller. Firstly, a bi-level framework is presented, where the objective is to minimize the payback period of RPFC and energy storage combined system in the outer planning layer to realize the optimal configuration of RPFC and energy storage location and capacity, and the objective is to minimize the annual operation cost in the inner operation layer with RPFC participating in the operation optimization as a flexible adjustment resource. Secondly, the hybrid optimization of genetic algorithm and Pulp solver is used to solve the optimal configuration model. Finally, the optimal configuration model is verified on the example of IEEE 33-node. The results verify the applicability of the proposed optimal configuration scheme of RPFC and energy storage combined system, which can effectively promote the renewable energy consumption, and improve flexibility and economy of system.
