摘要

为缓解新能源与负荷的时空刚性分布对分布式光伏消纳空间的制约

提出储能-智能软开关协同规划策略以提升配电网对分布式光伏的承载力。首先

为评估多端软开关（MSOP）和储能（ESS）在时空灵活性上的协作效益

提出一个整合支路电流时间均匀分布水平与网损灵敏度的评价指标。然后

基于协作效益评价指标建立由规划和运行组成的两层随机优化模型。该模型通过嵌入MSOP-ES模型能考虑MSOP和ESS的多样融合形态。最后

该两层优化模型由Benders分解算法高效求解。IEEE 33节点配电网和一个实际配电网上的算例分析表明

所提方法通过规划储能和多端软开关在有效提升光伏承载力的同时

缓解了电压稳定问题并增强了网络灵活传输能力。

Abstract

To alleviate the limitation on distributed photovoltaic integration imposed by the inflexibility of the spatiotemporal distribution of new energy and load

this paper proposes a co-planning strategy for energy storage and intelligent soft-switching to enhance the capability of power distribution networks for distributed PV power. Firstly

to evaluate the collaborative benefits of multi-port soft open point （MSOP） and energy storage system （ESS） in spatiotemporal flexibility

an evaluation metric integrating branch current time-uniformity level and network loss sensitivity is proposed. Subsequently

a two-level stochastic optimization model comprising planning and operation is established based on this collaborative benefit metric. By embedding the MSOP-ES model

this framework is capable of considering diverse integration forms of MSOP and ESS. Finally

the two-level optimization model is efficiently solved using the Benders decomposition algorithm. Case studies on the IEEE 33-node distribution network and a real-world distribution network demonstrate that the proposed method effectively enhances PV hosting capacity while improving voltage stability and flexible transfer capability by planning ESS and MSOP integration.
