Abstract

Aiming at the problem of active distribution network reconfiguration under DG uncertainty, a two-stage dynamic robust reconfiguration optimization method is proposed. In the first stage, the switch reconfiguration optimization of radial distribution network is carried out. In the second stage, the optimal power flow optimization of active distribution network with battery energy storage is carried out considering the uncertain budget set of DG output and load demand. Because the second stage optimization problem includes the charging and discharging state of battery energy storage, the nested column and constraint generation algorithm is used to transform the two-stage dynamic robust reconfiguration model into a bilevel iterative solution. The results of four distribution systems with different scales show that the proposed dynamic robust reconfiguration method of distribution network based on nested CCG has good convergence.
