摘 要:針對目前我國可再生能源占比逐步增加,而整體利用效率不高的問題,提出了將電動汽車作為主動負荷,消納微網中可再生能源的經濟調度模型,利用遺傳優化算法求解經濟調度模型。研究表明電動汽車的接入以及可再生能源的使用不但可以節約微電網的投產資金與運行維護費用、減少環境污染,還能夠充分發揮電動汽車作為主動負荷起到削峰填谷的作用,提高了微網的經濟性。
關鍵詞:電動汽車;微網;可再生能源;主動負荷;智能電網

Abstract: Aiming at the problem that the proportion of renewable energy sources in China is increasing gradually, but the overall utilization efficiency is not high, this paper proposed the economic dispatch model to take the electric vehicle as the active load to consume and absorb the renewable energy sources and the genetic algorithm was used to solve the economic dispatch model. The research result shows that the access of electric vehicles and the usage of renewable energy sources not only save the production and operating maintenance cost of microgrid and reduce the environmental pollution, but also give full play to the peak clipping and valley filling functions for the electric vehicles as active load, which improves the economy of microgrid.
Key words: electric vehicle; microgrid; renewable energy sources; active load; smart power grid
