摘要
随着经济的快速发展,电力行业和交通行业的含碳气体排放越来越严重。为缓解大气污染的压力,微电网和电动汽车逐渐成为研究热点。微电网是由多种分布式电源、储能和负荷所组成的单一可控的低压电网,而电动汽车属于移动的储能设备,在负荷高峰时可以通过电动汽车向微电网反向送电。本文提出了一种计及电动汽车不确定性的微电网规划方法,首先,通过蒙特卡洛仿真模拟电动汽车的使用特性,解决电动汽车接入微电网进行规划之前的运行不确定性;然后,运用非线性规划工具Lingo求解微电网规划模型;最后,通过算例结果验证该方法的有效性。算例结果表明:电动汽车以V2G形式接入微电网,会减小微电网系统规划总成本。
With the rapid development of economy,the carbon emissions from power industry and transportation industry is more and more serious.In order to alleviate the pressure of the air pollution,the power grid and electric cars gradually become a hot research topic.Micro-grid is a kind of low voltage power grid,which contains a variety of distributed power supply,energy storage device and load,and electric vehicle belongs to the movable energy storage device,which can reverse power supply to the micro-grid by electric vehicle during peak load.This paper proposes a method of micro-grid planning for the uncertainty of EY.Firstly,electric vehicles are simulated by Monte Carlo to solve the operation uncertainty of electric vehicle,and then,the nonlinear programming tool of Lingo is used to solve the micro-grid programming model.At last,the numerical results verify the effectiveness of the proposed method.The results show that the V2G of electric vehicles in the form of a nuanced grid will reduce the total cost of the micro-grid system planning.
