【摘要】：为了适应未来大量分布式电源(DG)并网及自动化水平显著提高的主动配电网发展,在规划阶段应该考虑主动管理措施,优化系统运行方式。同时,现有的无功补偿规划研究忽略了DG及负荷的不确定性。为此,计及间歇性DG及负荷的不确定性,提出主动配电网无功补偿双层优化配置模型。上层规划以无功补偿电容器的投资成本、网络损耗费用综合最优为目标函数,下层规划在此基础上考虑调节无功补偿容量及调节有载变压器抽头两种主动管理措施,对每个场景进行优化。采用K-均值聚类法对场景进行缩减,结合和声搜索算法和粒子群算法联合求解模型。通过IEEE33节点算例进行仿真计算,验证所提模型和方法的正确性。
[Abstract]:In order to adapt to the development of active distribution network with large amount of DGG in the future, and the level of automation is improved significantly, the active management measures should be considered in the planning stage, and the system operation mode should be optimized at the same time. The uncertainty of DG and load is neglected in the current reactive power compensation planning. Therefore, the uncertainty of intermittent DG and load is taken into account. A two-layer optimal allocation model for reactive power compensation in active distribution network is proposed. The upper level programming takes the investment cost and network loss cost of reactive compensation capacitor as the objective function. On this basis, the lower layer programming considers two active management measures, adjusting reactive power compensation capacity and adjusting tap of loaded transformer, and optimizes each scenario. K-means clustering method is used to reduce the scene. Combined with harmonic search algorithm and particle swarm optimization algorithm, the model is solved by IEEE33 node simulation, and the correctness of the proposed model and method is verified.
