Abstract:The distribution network reconfiguration mainly considers the grid information in the single scene when the fault occurs, but actually it is through the whole fault repair period, and thus only consider the grid information at the time of power failure may lead to the overload of the grid in subsequent periods. Given this background, the dynamic network reconfiguration scheme which takes into account the time-varying data is proposed. Firstly, an active distribution network reconfiguration algorithm considering distributed generation (DG) based on greedy algorithm is presented. Secondly, a model aims at minimizing the energy loss during the post-fault period is established, and then the single scenario optimization could be extended to continuous scenario optimization. Subsequently, the rolling optimization is employed to update the network reconfiguration scheme and adjust the power supply of the DGs. Finally, the simulation results demonstrate the effect of DGs on optimizing system recovery scheme and identify the effectiveness of the developed model and method.
