| 摘要: |
| 针对电动汽车规模化应用对电网规划运行带来的负面影响，提出采用集中式与分布式结合的优化控制理念，建立协调控制模型。集中式控制以电网负荷波动最小化作为优化目标，分布式控制以动态时间窗内充电需求与集中式优化控制结果之间的偏差、用户充电成本最小化以及延长电池寿命为优化目标，实现了电动汽车充放电的动态优化控制。以山东电网规划数据为例，考虑充电时间、充电模式、不同渗透率等因素，分析无序充电、时段控制充电、有序充电等多情景下电动汽车充电对配电网负荷的影响，结果验证了充电负荷模型和优化控制算法的有效性与可行性。 |

| Abstract: |
| Aiming at the negative impact of large scale application of EV（Electric Vehicle） on the planning and operation of power system，a concept combining centralized optimal control and distributed optimal control is put forward and a coordinated control model is established. In order to realize the dynamic optimal control of EV charging，the centralized control takes the minimal network load fluctuation as its optimization objective while the distributed control takes the minimal deviation between the charging load within a dynamic time window and the result of centralized optimal control，the minimal charging cost and the prolonged battery life as its objectives. With the planning data of Shandong Grid as an example and the consideration of different factors such as charging time，charging pattern and penetration rate，the impact of EV charging on distribution network is analyzed for different scenarios，such as uncoordinated charging，time-of-use scheduled charging and coordinated charging，which verifies the validity and feasibility of the charging load model and the optimal control algorithm. |
