摘　　要：随着电动汽车的普及,电动汽车接入电网(vehicle-to-grid,V2G)备用的引入将不可避免地影响传统备用市场交易模式。从可靠性和经济性角度,对比分析了V2G备用与发电备用的异同,指出了含V2G备用的市场交易特点,并分析了在一定可靠性要求下,未来交易中备用需求、供给与价格间之间的联动关系。以此为基础,提出了以购置成本和风险成本总和最小为目标,以可靠性综合电价作为衡量指标的计及V2G备用服务的备用交易新模式,并基于顺序投标法给出了具体求解方法。该模式综合考虑了电动汽车用户参与备用服务的违约概率和传统发电备用的事故概率,实现了V2G备用与发电备用的联合优化调度,为未来含V2G的备用服务交易模式提供了一种新思路。最后,通过算例验证了所提交易模式的有效性和正确性。With the popularity of electric vehicles, vehicle-to-grid （V2G） reserve will inevitably impact on the traditional reserve trading model. By analyzing the differences and similarities between V2G reserve and generation side reserve in terms of reliability and economy, this paper pointed out the trading features of the reserve market including V2G reserve, and analyzed the interactive relationships of the relevant reserve need, reserve supply and reserve price under the requirement of certain reliability. To achieve the minimal total cost of the purchase cost and risk cost of reserve trade, and taking reliability electricity price as measurement index, a new reserve trading model of electric companies concerning the V2G reserve was proposed. Furthermore, a specific solution method was put forward according to the sequential bidding. This new model, taking default probability of electric vehicle users and accident probability of generation side reserve into consideration, realized the optimal scheduling of the V2G reserve and generation side reserve, which provide a new way for future reserve trading model considering V2G reverse. Finally, the effectiveness and validity of the proposed trading model were illustrated by a numerical example.
