| 摘要: |
| 提出了一种含多微电网的柔性中压直流配电中心优化调度方法。首先介绍了中压直流配电中心系统的控制架构，集中控制器可以实现系统的局部自治和协同优化。分别对交流配电管理系统、中压直流配电中心和微电网进行建模。对于不同的集中控制器，采用不同的调度方法。微电网集中控制器采用日前调度和滚动优化相结合的调度方法，以微电网的运行成本最小为目标。MMC集中控制器采用实时调度的调度方法，以配电网的有功损耗和交流线路负载均衡率的加权和最小为目标。最后通过算例验证调度方法的可行性。 |

| Abstract: |
| In this paper, an optimal dispatching method with multi-microgrid for flexible medium voltage DC distribution center is proposed. The control architecture of the medium voltage DC distribution center system is introduced firstly. The local autonomy and collaborative optimization of the system can be achieved by the concentrated controllers. The distribution network, medium voltage DC distribution center and microgrids are modeled separately. For different centralized controllers, different dispatching methods are introduced. A combination of daily dispatching and rolling optimization is adopted by the microgrid concentrated controllers with the goal of minimizing the operating cost of the microgrid. A real-time dispatching method is adopted by the MMC concentrated controller with the goal of minimizing weighted sum of the active loss of the distribution network and the load balancing rate of the line. Finally, the feasibility of the dispatching method is verified by an example. This work is supported by Key Project of China Southern Power Grid (No. GZKJQQ00000417). |
