| 摘要: |
| 结合海岛环保公共交通需求并基于车网互联（V2G）技术，提出一种将电动公交汽车电池集群（EBBG）作为储能元件参与海岛微网能量调控的运行方案。根据EBBG的配置参数和管理模式，构建精确的数学模型实时评估其V2G可用容量，表征其参与微网运行调控时的动态双向能量平衡能力。以实现各优化时段内海岛微网中供需两侧能量动态平衡的整体成本最小化为目标，建立EBBG参与海岛微网运行调控的优化模型，并基于改进粒子群优化算法求得系统中各能量动态平衡要素在各时段的功率输出最优值。以舟山东福山岛风-光-柴-储微网系统为例，验证了所提V2G能量调度方案和运行优化策略的可行性和有效性。 |

| Abstract: |
| Combined with the demand of green island public transportation，an energy dispatch scheme based on V2G（Vehicle to Grid） technology is proposed for island microgrid，which takes the EBBG（Electric Bus Battery Groups） as the energy storage devices. A precise mathematical model is established based on the configuration parameters and management mode of EBBG to estimate the available V2G capacity in real time for representing its dynamic ability of bidirectional energy balance. An optimization model with the minimum total operational cost of the dynamic energy balance between supply and demand sides as its objective is built for different optimization periods. The improved particle swarm optimization algorithm is applied to calculate the optimal power outputs of all energy balance elements for different optimization periods. With the wind-PV-diesel-battery hybrid microgrid of Dongfushan Island in Zhoushan as an example，the feasibility and validity of the proposed V2G-based energy dispatch scheme and operational optimization strategy are verified. |
