Economic Dispatch of Active Distribution Network Based on Beetle Antenna Search Algorithm

为提高主动配电网的经济效益,在考虑分布式能源、网损费用和发电成本基础上,建立了主动配电网经济调度模型。模型加入了柔性软开关对主动配电网进行灵活调度和无功优化,使用优化后天牛须搜索算法对其进行求解,优化方法为在算法中加入遗传因子和锦标赛选择策略,使算法结果不会陷入局部最优,得到最小发电成本。最后经仿真实验,验证了优化后的天牛须搜索算法在主动配电网经济调度问题中具有实用性和高效性。

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.
