| 摘要: |
| 未来电力系统中电动汽车保有量会相当庞大，由调度机构直接控制每辆电动汽车进行有序充电是不现实的，比较可行的方案是由代理商和电网调度中心共同对电动汽车进行分层分区管理。基于此，提出包括电网调度中心、区域能量管理系统(Area-EMS)和微调度能量管理系统(μ-EMS)的电动汽车充电分层能量管理架构，并详细阐述各个层级的功能以及该架构模型的运行原理；针对代理商负责的Area-EMS和μ-EMS分别提出两级实时能量管理策略，该策略在满足电动汽车充电需求和保证经济效益的同时，能够适应不同的电网耦合模式，改善区域电网的负荷峰谷特性；通过仿真算例验证所提分层架构和实时能量管理策略的有效性和实用性。 |

| Abstract: |
| A large number of electric vehicles will be integrated into the power system in the promising future. In this case, it is more or less unrealistic to directly dispatch each electric vehicle for orderly charging. A more realistic plan is to manage those electric vehicles in different levels and zones in a decentralized basis. In this regard, an EV charging layered energy management architecture including power system dispatching center, Area-EMS(Area Energy Manage System) and μ-EMS(fine-tuning Energy Management System) is proposed. The function of each layer and the operation scheme of the layered management architecture are introduced in detail. A two-stage real-time energy management strategy is designed for Area-EMS and μ-EMS in charge of agents respectively. The strategy can satisfy the charging needs of electric vehicles and ensure economic benefits. Moreover, this strategy is adaptive to different power grid coupling modes, and can improve load peak-valley characteristics of regional power grid. Simulation examples are conducted to verify the effectiveness and practicability of the proposed layered architecture and real-time energy management strategy. |
