摘要
随着电动汽车的商业化,电动汽车与电网相连V2G(vehicle to grid)之间的影响也受到关注。电动汽车配备的大容量储能装置可以很好的作为电网的分布式储能设备。提出通过电动汽车互联到电网,来解决新能源并入电网引起的频率波动问题。将处于闲置状态的电动汽车聚合在一起,对大规模电动汽车采取预设智能充放电控制,通过充电桩对电网进行双向功率传输,以此来对电网频率偏移进行抑制。通过仿真分析,当电动汽车达到一定规模时,充分利用电动汽车的储能特性可以有效缓解区域电网的频率偏移。
With the commercialization of electric cars, electric cars and grid connected V2G （vehicle to grid） between the influence is also of coneern. Large capacity storage electric vehicle equipped with the device can be vely good to be distributed network storage device. In this paper through the electric ear connected to the grid, to solve the grid frequency deviation caused by power fluctuation of distributed energy. For eleetrie vehicles using the preset smart charging control, will be in the idle state of the electric car charging pile together. Through the power grid for two-way transmission, in order to restrain the power frequency offset. Through the simulation arlalysis, the number of electric cars in a certain area is large enough, can effectively inhibit the frequency Offset in regional power grid.
