摘　　要：在主动管理(AM)模式下,提出了一种考虑主动配电网转供能力的可再生电源(RES)优化配置模型。以年综合费最小为上层目标,每个场景的配电网运行费最小为下层目标,该模型计及了系统故障负荷的转供和包括RES出力切除、RES功率因数调整、有载调压变压器分接头调节和需求侧管理在内的4种AM措施。考虑RES出力随机性及负荷波动性,利用准蒙特卡罗模拟和奇异值分解生成风、光荷相关性样本矩阵并采用模糊C-means聚类对场景进行缩减。应用动态小生境差分进化与原对偶内点算法相联合的策略对模型加以求解。通过算例对比是否考虑AM措施和转供能力下的三种情境仿真结果验证了模型和方法的有效。Under the active management（ AM） mode, an optimal Renewable Energy Sources（ RES）allocation model is proposed. The model takes the minimum annual total cost and the minimum scenario-based distribution network operation cost as the objectives of upper and lower level,respectively. The power transfer of system fault load and four AM schemes are considered in the optimization formulation. The AM schemes including RES output power resection,RES power factor adjustment,on-load regulating transformer tap adjustment and inside management measures. Given the randomness of RES output power and load fluctuation, the correlation between wind and light load sample matrix is generated by quasi Monte Carlo simulation and singular value decomposition and then simplified by fuzzy C-means clustering. A hybrid strategy combining dynamic niche differential evolution algorithm and primal-dual interior point method is applied to the model. The compared simulation results demonstrate the effectiveness of the proposed model and method.
