新能源电动汽车光储充研究设计

Research and Design of New Energy Electric Vehicle Optical Storage and Charging

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超额等问题,进而对系统输电和发电能力造成很大压力。将光伏发电经储能系统与充电桩相结合,不仅能缓解电网系统的压力,而且所建成的光储充系统在发电过程中无环境和噪声污染,实现了清洁能源的利用,也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,提高供电可靠性的情况。在提倡绿色环保、节能减排,大力发展新能源的时代此设计方案具备良好的推广前景。

With the increasing power demand for electric vehicle charging,large-scale electric vehicle charging may cause the operation index of the distribution network to exceed the limit.At the same time,it may also cause problems such as excessive peak load of the system,which in turn will affect the power transmission and generation capacity of the system.The combination of photovoltaic power generation via energy storage system and charging pile can alleviate the pressure on the grid system,and the built solar storage and charging system has no environmental and noise pollution during the power generation process,and realizes the use of clean energy.In order to improve the reliability of power supply,it is possible to use light to maintain piles,cut peaks and fill valleys,stabilize charging load fluctuations,reduce pressure on grid capacity,and improve power supply reliability.In the era of promoting green environmental protection,energy saving and emission reduction,and vigorously developing new energy,this design has a good promotion prospect.
