| 摘要: |
| 为了实现多能互补微网中分布式能源的有效利用、对本地负荷的可靠优质供电以及微网与主网之间功率的灵活调配，基于模块化多电平换流器型统一电能质量控制器(MMC-UPQC)，提出一种MMC型三端主动电力调节系统，讨论并分析了MMC型三端主动电力调节系统的组成及其在多能互补微网中的运行模式，设计了协调控制策略以实现微网中电能质量综合治理兼顾微网与主网之间功率可控调节的一体化功能。通过PSCAD/EMTDC仿真分析验证了MMC型三端主动电力调节系统在多能互补微网中综合实现电能质量治理和灵活优质供电功能的可行性和有效性。 |

| Abstract: |
| An active three-terminal power conditioner based on MMC-UPQC(Modular Multilevel Converter based Unified Power Quality Controller) is proposed for the multi-energy complementary microgrid to realize the efficient utilization of distributed energy sources, the reliable power-supply to local loads and the flexible power dispatch between it and grid. Its constitution and operating modes are analyzed and a coordinated control strategy is designed to realize the integrated control function of comprehensive microgrid power-quality management and controllable power dispatch between microgrid and grid. The feasibility and effectiveness of the proposed conditioner in implementing the integrated control function of multi-energy complementary microgrid are verified by PSCAD/EMTDC simulations. |
