| 摘要: |
| 为提高风、光分布式电源在主动配电网中的渗透率，计及风-光-荷时序相关特性提出主动配电网源-储规划策略。针对风、光分布式电源以及负荷的时序波动特性，采用改进模糊C均值聚类算法合成风-光-荷时序全场景。综合考虑分布式电源渗透率、消纳水平、经济效益及电压偏差指标建立多目标规划模型。采用混沌粒子群算法进行求解，引入适应度计算改善其全局寻优能力，得到源-储多目标规划解集。通过对东北地区某47节点配电系统的仿真，得到源-储多目标规划方案，并根据电压累计概率密度对规划方案进行评价。结果验证了所提方法的正确性和可行性。 |

| Abstract: |
| In order to improve the permeability of wind turbines and photovoltaics in an active distribution network, an active distribution network source-storage planning strategy is proposed considering wind-photovoltaic-load timing characteristics. Aiming at the time series fluctuation characteristics of distributed generation and load, the improved fuzzy C-means clustering algorithm is used to synthesize the wind-photovoltaic-load time scenarios. A multi-objective planning model that comprehensively considers distributed generation permeability, consumption level, economy, and voltage stability indicators is established. To solve the multi-objective planning model, the chaotic particle swarm optimization algorithm is used to improve and optimize the global optimization ability by introducing a congestion degree calculation strategy and an elite retention strategy. By simulating a 47-node power distribution system in a certain area, a source-storage multi-objective planning strategy is obtained, and the optimization scheme is evaluated based on the cumulative voltage density. The results verify the correctness and feasibility of the proposed method.
