摘要:

高比例可再生能源并网和多样化负荷接入加剧了新型配电系统高运行成本和高电压偏差运行风险。针对目前新型配电系统配置阶段未在多时间尺度下考虑运行风险和多元时空灵活性资源协同配置的问题,提出考虑运行风险的新型配电系统多元时空灵活性资源协同配置模型。首先,采用蒙特卡洛抽样和K-means聚类算法生成源-荷场景集,并利用多尺度形态学算法对源-荷曲线波形进行多尺度分解;然后,基于条件风险价值(conditional value at risk,CVaR)理论量化评估配电系统多时间尺度运行风险,并在此基础上建立考虑运行风险的新型配电系统多元时空灵活性资源双层配置模型。其中,上层以配电系统年综合成本最小为目标函数对多元时空灵活性资源进行协同配置,下层以期望损失值和基于CVaR的运行风险值最小为目标对系统进行运行优化。最后,通过改进的IEEE 33节点系统进行算例分析,结果表明:所提方法可以有效降低配电系统高运行成本和高电压偏差的运行风险。

Abstract:

The high proportion of renewable energy integration and diversified load connections have exacerbated the operational risks of high operating costs and high voltage deviations in new distribution systems. To address the issue that the current new distribution system does not consider the operational risks and the collaborative configuration of multi-temporal and spatial flexible resources across multiple time scales during the configuration phases, this paper proposes a collaborative configuration model for multi-temporal and spatial flexible resources considering operational risks. Firstly, a source-load scenario set is generated using Monte Carlo sampling and the K-means clustering algorithm, and the multi-scale morphological algorithm is employed to decompose the source-load curve waveforms at multiple scales. Then, based on the conditional value at risk (CVaR) theory, a quantitative assessment of the multi-temporal operational risks in the distribution system is conducted. On this basis, a bi-level configuration model for multi-temporal and spatial flexible resources considering operational risks is established. In this model, the upper level aims to minimize the annual total cost of the distribution system for collaborative configuration of the multi-temporal and spatial flexible resources, while the lower level focuses on minimizing the expected loss value and the CVaR-based operational risk value for system optimization. Finally, an improved IEEE 33-node system is used for case study, validating the proposed method can effectively reduce the operational risks related to high operating costs and voltage deviations in the distribution systems.
