摘 要：研究了并網(wǎng)狀態(tài)下的微電網(wǎng)經(jīng)濟(jì)運(yùn)行，并將改進(jìn)的帝國競爭算法運(yùn)用到并網(wǎng)模式下的微電網(wǎng)經(jīng)濟(jì)調(diào)度中。建立包含光伏、風(fēng)機(jī)、燃料電池及蓄電池的微電網(wǎng)并網(wǎng)運(yùn)行模型，調(diào)度模型以微電網(wǎng)運(yùn)行成本最小為目標(biāo)，以各個機(jī)組的出力限制、功率平衡、儲能情況等為約束條件，由于帝國競爭算法在計算時收斂速度慢，將模糊隸屬函數(shù)與輪盤算法引入帝國競爭算法來求解所建立的數(shù)學(xué)模型，通過改進(jìn)的帝國競爭算法求得了最佳的出力方式。

Abstract: 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.
Key words: microgrid; economic dispatch; fuzzy membership function; roulette algorithm; imperial competition algorithm
