摘要
随着电动车辆充电需求功率不断增大,规模化的电动汽车充电可能会导致配电网运行指标越限,同时还可能引起系统峰值负荷增长等问题,进而对系统输电和发电能力造成压力。针对上述问题,结合分布式能源的特性,分析不同微电网系统的优缺点,结合客户实际需求,给出工程配置原则及方法,分析项目收益。由此实现了以光养桩,削峰填谷,平抑充电负荷波动,降低电网容量压力,提高供电可靠性,具备良好的推广前景。
With the increasing power demand of electric vehicles,large-scale electric vehicles charging may cause the operation of the distribution network to exceed the limit.At the same time,it may also cause problems such as system peak load growth,which may put pressure on the system transmission and power generation capabilities.In view of the above problems,combining the characteristics of distributed energy,the advantages and disadvantages of different micro-network systems was analyzed,the principles and methods of project allocation were given,and the project revenue was analyzed.This paper realizes the use of light-raised piles,the peak shaving and valley filling,smoothing the fluctuation of charging load,reducing the grid capacity pressure,improving the reliability of power supply,which has a good prospect of promotion.
