摘要/Abstract

摘要： 分布式电源的高渗透率接入使得配电网运行波动性剧增，潮流流向多变，并可能带来电压越限、功率倒送、经济性差等问题。针对上述问题，挖掘智能软开关、移动储能等新型电力电子装置对柔性配电网的调控潜力，提出了一种考虑移动储能接入的柔性配电网运行优化策略。首先，对柔性配电网中多类型设备进行建模，通过智能软开关直流环节接入移动储能，建立了含移动储能接入的智能软开关模型。其次，计及系统潮流约束、柔性设备运行约束、移动储能运行约束等多类型约束，以最小化电网运行成本为目标函数，提出了考虑移动储能接入的配电网运行优化策略。最后，利用改进的IEEE 33节点配电网进行算例测试，验证了所提方法的有效性并分析了所提方法对高比例分布式电源接入下配电网运行经济性的提升效果。

Abstract: The high penetration of distributed generators (DGs) exacerbates the operation volatility of distribution networks, which seriously challenges the economic and safety operation of distribution networks. In order to avoid the problems caused by high penetration of DG integration, a novel operation optimization strategy for flexible distribution network (FDN) is proposed considering the applications of soft open point (SOP) and mobile energy storage (MES). Firstly, the model of FDN with multi-type devices is described, which can use the potential of controllable resources for flexibility improvement. The MES is accessed to the distribution network through the DC link of SOP, and the SOP model with mobile energy storage access is established. Secondly, the optimal operation strategy is proposed to facilitate the flexible operation of FDN, considering the power flow constraints, flexible devices operation constraints and MES operation constraints. Finally, the modified IEEE 33-node system is used to verify the effectiveness of the proposed method, which shows that the network losses are effectively reduced and the voltage profile is improved due to the coordination of SOP and MES.
