| 在“双碳”目标与新型电力系统建设背景下,电动汽车规模化接入加剧了电网灵活性调节压力,亟需挖掘其可调节潜力并提升聚合运行价值。针对充电运营商跨市场参与现货与调频辅助服务的协同优化需求,构建了面向现货-调频耦合市场的双层优化调度模型。上层以充电运营商收益最大化为目标,综合计及购售电收益、调频容量补偿、调频里程补偿及运营成本;下层以系统运行成本最小化为目标,联合出清现货市场与调频市场。进一步引入卡罗需-库恩-塔克条件(karush-kuhn-tucker conditions,KKT)条件与线性化处理方法,将双层规划转化为混合整数线性规划,并基于IEEE-30节点系统开展算例验证。结果表明,充电运营商在现货市场中的中标比例相对有限,但在调频市场中承担了超过70%的调节任务,不仅有效覆盖运营成本,而且获得了显著净收益。所构建策略能够协调现货与调频市场间的资源配置与价格传导关系,在提升充电运营商经济效益的同时增强系统灵活性供给能力,为电动汽车聚合体跨市场优化运行提供了理论依据与方法支撑。 |

| Under the dual-carbon goal and the ongoing development of a new-type power system, greater flexibility challenges are imposed on power system operation by the large-scale integration of electric vehicles (EVs), and the adjustable potential of EV resources therefore needs to be further exploited. To address the coordinated optimization problem of charging point operators (CPO) participating in coupled energy and frequency regulation markets, a bilevel scheduling model is established. In the upper level, CPO profit maximization is pursued, with electricity trading revenue, frequency regulation capacity compensation, mileage compensation, and operating cost all being considered. In the lower level, total system operating cost minimization is achieved through the joint clearing of the energy market and the frequency regulation market. The bilevel model is then transformed into a mixed-integer linear programming problem by introducing karush-kuhn-tucker conditions and linearization techniques, and case studies are conducted on the IEEE 30-bus system. The results show that only a limited proportion of bids is cleared in the energy market, whereas more than 70% of the regulation tasks are undertaken by the CPO in the frequency regulation market. As a result, operating costs are effectively covered and positive net benefits are obtained. Effective coordination between resource allocation and price formation in the coupled markets is also achieved by the proposed strategy. Both the economic performance of the CPO and the flexibility support capability of the power system are thereby improved. A feasible theoretical basis and methodological support are thus provided for the cross-market optimal operation of aggregated EV resources. |
