计及电动汽车车主意愿的集成光热充电站优化运行策略

摘要

Since CSP(Concentrating Solar Power) station may operate well together with EV(Electric Vehicle) charging station due to its favourable operating performances,an integrated framework of CSP station and EV charging station is proposed.According to their selection of charging power and willingness of discharging from EV to the power system,the EV owners are classified into three types:radical,conservative and friendly,and the charging/discharging behaviour models are built for three EV owner types.A mixed integer linear planning model is then established to optimize the operation of CSP-based EV charging station,which takes the maximum total operational profit of the integrated station as its objective and considers fully the power generation cost,maintenance cost,EV owner's benefits in different charging/discharging modes,and power flow constraints among units of the integrated station.AMPL/CPLEX is applied to solve the developed optimization model and examples are analyzed to illustrate the basic features of the proposed method.%光热发电(CSP)电站具有良好的运行特性,能和电动汽车(EV)充电站联合运行,由此形成的光热充电站具有较好的应用前景.在此背景下,提出了一种CSP电站与EV充电站的集成架构.根据EV车主对充电功率的选择和是否允许EV向电力系统放电,将EV车主细分为激进型、保守型和友好型3种类型,并对不同类型EV的充放电行为进行建模.然后,建立了CSP电站与EV充电站集成系统运行优化的混合整数线性规划模型,以总体运营收益最大为优化目标,并充分考虑了集成系统的发电成本、运维成本、EV采用不同充放电模式的收益以及集成系统各单元之间的功率流约束.最后,采用AMPL/CPLEX求解所建立的优化模型,并通过算例分析说明了所提方法的基本特征.
