摘要(Abstract):
目前,各国正在大力发展新能源电动汽车以缓解石油危机和环保压力,而大量电动汽车接入电网后增加了电网负荷,加剧了负荷峰谷差,增加了居民的用电成本,进而降低了电网稳定性与经济性。针对上述问题,建立并分析了某小区的电动汽车无序充电负荷模型,提出一种利用分时电价调控充电时间的充电策略,以该小区负荷方差与电动汽车充电费用为评价指标,优化电动汽车的充电时间。算例表明,利用上述充电策略,可以有效削减由电动汽车入网所造成的负荷峰谷差,达到移峰填谷的效果,大大降低了电动汽车的充电费用。
At present,all countries are vigorously developing new energy electric vehicles to ease the oil crisis and environmental protection pressure. However,a large number of electric vehicles are connected to the grid,thus the grid load is increased the load peak-to-valley difference is aggravated,and the electricity cost of residents is increased and the economy and stability of the power grid are reduced. In view of the aforementioned problems,this paper establishes and analyzes the random charging load model of electric vehicles in a residential quarter,and proposes a charging strategy that adjusts the charging time by using the time-of-use price of electricity,which uses the load variance of the residential quarter and the charging cost of electric vehicles as evaluation indexes to optimize the charging time of electric vehicles. The example shows that the aforesaid charging strategy can effectively reduce the peak-valley difference of load caused by grid integration of EVs,achieve the effect of peak-shifting and valley filling,and greatly reduce the charging cost of EVs.
