电网与交通网耦合的设施规划与运行优化研究综述及展望

Review and Prospect of Research on Facility Planning and Optimal Operation for Coupled Power and Transportation Networks

新能源汽车保有量迅速增长,其能源补给需求对电网规划和运行的影响已不容忽视。同时,随着风电和光伏发电装机占比的持续提升,电网也亟须利用电动汽车补能需求的灵活性来平抑新能源发电出力和负荷功率的波动。促进电网与交通网的耦合能够提升社会效益,实现多方共赢。文中首先对电网与交通网两网耦合的关键基础设施及主要利益相关方进行分析。其次,论述当前和无人驾驶条件下两网耦合的基本模式与目标。接着,着重对考虑两网耦合的设施规划和运行调控问题的研究现状进行归纳和总结。最后,对两网耦合的规划和运行优化相关方向需进一步研究的问题进行分析和展望。

With the rapid growth of the number of new energy vehicles,the impact of their energy supplement demands on the planning and operation of power grids cannot be ignored any more.At the same time,with the continuous increase in the installed capacity proportion of wind and photovoltaic power generation,the power grids also urgently need to utilize the energy supplement demand flexibilities of electric vehicles(EVs)to smooth the fluctuations of renewable energy generation output and load power.Promoting the coupling of power and transportation networks can bring social benefits and achieve a win-win situation for all parties.This paper firstly analyzes the key infrastructures and the major stakeholders for the coupling of power and transportation networks.Secondly,the basic mode and objectives of the coupling of the two networks under current and unmanned driving conditions are discussed.Thirdly,the research status of the facility planning,operation,dispatch and control considering the coupling of the two networks is reviewed and summarized.Finally,this paper analyzes and prospects several problems that need to be further studied in the planning and operation optimization for the coupling of the two networks.
