Abstract: With the continuous addition of distributed generation to the distribution network, the output of active distribution network will be unstable and the supply-demand side will be unbalanced, and its economic aspects need to be further studied. Based on the consideration of distributed energy, network loss cost and generation cost, an economic dispatching model of active distribution network is established. It adds soft open point to carry out flexible dispatching and reactive power optimization of active distribution network, and solves it by using the optimization beetle antennae search algorithm. The optimization method is to add genetic factor and tournament selection strategy to the algorithm. The algorithm results will not fall into local optimization and the minimum generation cost is obtained. Finally, the simulation results show that the optimized beetle antennae search algorithm is practical and efficient in the economic dispatching problem of active distribution network.
