摘要

潮流分析是交直流混合微电网规划、设计和优化运行的基础。针对电力电子变压器的引入对交直流混合微网潮流分布的影响,本文将对基于电力电子变压器的交直流混合微网进行潮流分析。首先,提出了基于电力电子变压器的交直流混合微网拓扑结构,给出了微网源、负载和存储的配置。其次,在Simulink中建立了交直流混合微电网潮流分析的等效模型。最后,分别对有无电力电子变压器的交直流混合微电网进行了潮流分析。仿真结果表明,电力电子变压器能使混合交直流微电网充分消耗新能源,有效实现源、网、负荷、蓄的优化协调运行。

Power flow analysis of hybrid AC/DC microgrid based on power electronic transformer
Power flow analysis is the basis for planning, design and optimized operation of Hybrid AC/DC microgrids. Aiming at the impact of the introduction of power electronic transformers on the power flow distribution of the Hybrid AC/DC microgrid, this paper will carry out the power flow analysis of the Hybrid AC/DC microgrid based on the power electronic transformer. First, the topology of the Hybrid AC/DC microgrid based on power electronic transformer is proposed, and the configuration of the source, load, and storage of the microgrid is given. Next, an equivalent model for power flow analysis of Hybrid AC/DC microgrid is established in Simulink. Finally, the power flow analysis of AC and DC hybrid microgrid with and without power electronic transformers is carried out respectively. The simulation results show that the power electronic transformer can make the Hybrid AC/DC microgrid fully consume new energy, and effectively realize the optimized and coordinated operation of source, grid, load, and storage.
