多情形下电动汽车与分布式光伏协同优化调度算法

Optimal Dispatch Algorithm of Electric Vehicle Interconnected with Distributed PV Under Difference Circumstances

在智能电网环境下,电动汽车与家庭用电互动(vehicle to home,V2H)技术成为车电互联研究领域新的焦点。首先,对V2H模式中家庭能源管理系统调度电动汽车参与家庭供电进行了分析;其次,以最大化利用太阳能,减少家庭用电费用为目标,给出多情形下电动汽车与含分布式光伏(photovoltaic,PV)的智能家居互动的调度优化算法;最后,以上海市某小区用户为例,对比研究了晴天、多云、阴雨3种天气条件下光伏出力变化和电动汽车用户短途、中途、长途出行情况下V2H模式的经济效益。实际算例结果表明含分布式光伏的V2H模式能够提高光伏发电利用效率,减少家庭用电费用,并为电动汽车安全接入电网提供支持。

When it comes to the smart grid,the technology,V2 H,short for vehicle to home,has become a hot topic in the research field of vehicle to grid. This paper firstly analyzes the household electricity supply that is partly dispatched by electric vehicle controlled by household electricity management system in V2 H mode. And second,we,with the goal to make the best of PV and reduce residential electricity bills,presents the optimal algorithm for the dispatch between electric vehicle and smart home with distributed photovoltaic（ PV）. Finally,we take one residential district in Shanghai for example,and investigate the PV output in sunny,cloudy and rainy days,and the economic benefits of electric vehicle users who take short,midw ay and long trip,in V2 H mode. The actual calculation results show that the V2 H mode with distributed PV,which will be a support for electric vehicle to parallel in the grid,can increase the efficiency of PV power generation,and therefore reduce residential electricity bills
