Abstract: To improve the operation efficiency of active distribution network with battery energy storage system(abbr. 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.
