| 摘要: |
| 电动汽车充放储一体化充换电站作为区域性有源电站，通过合理的充放电控制策略，可以为电网提供削峰填谷的作用。根据电网状态和一体化充换电站与电网之间的能量流信息，结合换电站和梯次站的储能水平，对换电站、梯次站和电网之间的能量流动进行合理调控。将换电站和梯次站内电池组分成若干部分，结合电网实时负荷水平，提出一种新型的充放电控制策略，从而在保证换电站内满电状态电池组数量的前提下，为电网提供增值服务。所提充放电控制策略考虑电池的使用寿命，合理安排电池组在一个周期内的充放电功率。实际算例的分析结果表明，一体化充换电站在保证电池组使用寿命和满足自身良好运行工况的前提下，可为电网提供削峰填谷的服务。 |

| Abstract: |
| As a regional active power station, the EV charging-discharging-storage integrated station can offer peak load shifting for power grid by reasonable charging/discharging control strategy. According to the energy flow information between the integrated station and power grid and the state of power grid, considering the energy storage level of battery swap station and battery echelon station, the energy flow among battery swap station, battery echelon station and power grid can be controlled and dispatched reasonably. The battery packs in battery swap station and battery echelon station are departed into several parts. Considering the load level of power grid, a novel charging/discharging control strategy of battery packs is proposed to offer value-added services for power grid while satisfying the quantity of battery packs with full charge in battery swap station. The charging/discharging power of battery packs in a period of time is arranged in the proposed charging/discharging control strategy, considering the lifetime of batteries. Analysis results of example show that, the integrated station can offer the service of peak load shifting for power grid while ensuring the service life of battery packs and satisfying their good operational status. |
