| 摘要: |
| 基于电动汽车(EVs)移动负载和储能特性，提出含EV的微网分布式电源(DGs)选址定容模型和EV运行管理策略。利用电价引导机制，制定EV无序充电、有序充电和有序充放电3种能量管理模式。以投资成本、交互功率波动率、孤岛失负荷率最小为目标，采用基于精英策略的非支配排序遗传算法(NSGA-Ⅱ)求解DG优化配置方案。仿真结果表明，与EV无序充电模式相比，EV有序充电和有序充放电模式可以有效减少DG配置容量，降低微网综合成本，减小交互功率波动，EV延迟充电与放电辅助服务可显著提高微网孤岛供电可靠性。 |

| Abstract: |
| A siting and sizing model of microgrid DGs(Distributed Generators) including EVs(Electric Vehicles) and a corresponding strategy of EV operation and management are proposed according to the properties of EV as a moving load and energy storage. Three EV energy management modes are developed based on the price incentive mechanism, i. e. uncoordinated charging, coordinated charging, and coordinated charging/discharging. With the minimum investment cost, the minimum interactive power fluctuation rate and the minimum islanded microgrid power-loss probability as the optimization objectives, the NSGA-Ⅱ(Non-dominated Sorting Genetic Algorithm Ⅱ) based on the elitist strategy is adopted to solve the model for getting the optimal DG planning scheme. Simulative results show that, compared with the uncoordinated charging mode, the coordinated charging and coordinated charging/discharging modes may effectively reduce the planning capacity of DGs, decrease the overall cost of microgrid and smooth the interactive power fluctuation. The ancillary service of EV delay charging/discharging may remarkably enhance the power-supply reliability of islanded microgrid. |
