    摘 要:为降低微电网发电成本,考虑实际运行的约束条件,以调度周期内发电总成本最小为目标建立模型。为防止天牛须搜索算法( 简称天牛算法) 陷于局部最优,将Metropolis准则加入标准天牛算法中增加变异的概率,并将改进天牛算法与标准天牛算法分别求解微电网日前调度模型,仿真结果表明,利用改进算法求出的调度方案能够合理安排机组的出力,降低并网模式下微电网运行的总发电成本。

    Abstract: In order to reduce the generation cost of micro-grid, considering the constraints of actual operation, the model is established with the goal of minimizing the total power generation cost in the dispatch period. In order to prevent the beetle antennae search algorithm from falling into the local optimum, the Metropolis criterion was added to the standard beetle antennae search algorithm to increase the probability of mutation, and the improved beetle antennae search algorithm and the standard beetle antennae search algorithm were separately solved for the day-ahead scheduling model of the micro-grid. The simulation results show that the dispatch plan obtained by the improved algorithm can reasonably arrange the output of the units and reduce the total power generation cost of the micro-grid operation in the gridconnected mode.
    Key words: micro-grid; economic dispatch; beetle antennae search algorithm; Metropolis criterion
