Economic Dispatching and Collaborative Optimization of Active Distribution Network With Energy Storage

为了提升电池储能系统的有源配网运行效益,提出面向电池储能有源配网,包含经济调度与协同优化方法的分层递阶系统架构。首先,概述模型中不同层级间的逻辑运算关系;其次,针对不同层的优化目标,建立含光-储-充有源配网的经济调度与优化的2阶段模型。第1阶段以系统成本最小化为优化目标,第2阶段以系统网损最小为目标进行建模与仿真。最后,基于不同运行场景下的仿真结果,分析光、储、充的变化规律,并给出储能系统在不同节点的优化配置方案。

To improve the operation efficiency of active distribution network with battery energy storage system(BESS),a hierarchical architecture including economic scheduling and collaborative optimization method for active distribution networks with BESS was proposed.Firstly,the logical operation relationship between different levels in the model was overviewed.Secondly,a two-stage economic dispatching and optimization model of the active distribution network with photovoltaics-BESS-charging was established,which the first stage was to minimize the system cost,and the second stage was to minimize the system network loss.Finally,based on the simulation results under different operating scenarios,the variation rules of photovoltaic-BESS-charging were analyzed to obtain the optimal configuration scheme of BESS.
