【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]:In order to realize the effective utilization of distributed energy in multi-energy complementary microgrid, reliable and high quality local load power supply and flexible power allocation between microgrid and main network can be realized.Based on the MMC-UPQC controller of modular multilevel commutator, a three-terminal active power regulation system of MMC is proposed. The composition of the three-terminal active power regulation system of MMC and its operation mode in the multi-energy complementary microgrid are discussed and analyzed.A coordinated control strategy is designed to realize the integrated function of integrated power quality control and power controllable regulation between the microgrid and the main network.The feasibility and effectiveness of MMC three-terminal active power regulation system in multi-energy complementary microgrid integrated power quality management and flexible high-quality power supply function are verified by PSCAD/EMTDC simulation analysis.
