摘要
研究了并网状态下的微电网经济运行,并将改进的帝国竞争算法运用到并网模式下的微电网经济调度中。建立包含光伏、风机、燃料电池及蓄电池的微电网并网运行模型,调度模型以微电网运行成本最小为目标,以各个机组的出力限制、功率平衡、储能情况等为约束条件,由于帝国竞争算法在计算时收敛速度慢,将模糊隶属函数与轮盘算法引入帝国竞争算法来求解所建立的数学模型,通过改进的帝国竞争算法求得了最佳的出力方式。
In this paperthe economical operation of the microgrid under grid-connected state is studied,and the improved imperial competition algorithm is applied to the microgrid economicdispatch under the grid-connected mode.A microgrid grid-connected operation model including photovoltaics,wind turbines,fuel cells,and batteries is established.The dispatch model aims at minimizing the operation cost of microgrid,and it takes the output limitation,power balance and energy storage of each unit as constraints.Due to the slow convergence speed of imperial competition algorithm,the fuzzy membership function and roulette algorithm are introduced into imperial competition algorithm to solve the established mathematical model problem.The improved output method was obtained through the improved imperial competition algorithm.
