摘要
文章针对现有各类微电网的拓扑结构,利用转换环节的IGBT/DIODE损耗计算模型,结合高斯-赛德尔潮流算法,提出了考虑转换损耗模型的微电网高斯-赛德尔顺序潮流算法,并运用此法在Matlab/Simulink环境下分析比较了树干式直流、交流、混合微电网和环形直流、交流微电网的效率。仿真结果显示,在假定负荷功率因数为0.8的情况下,环形直流微电网的效率最高,树干式交流微电网的效率最低。
According to all kinds of microgrid topologies, using IGBT/DIODE loss calculation model of conversion, combined with the Gauss-Seidel power flow algorithm, a modified Gauss-Seidel power flow algorithm,which includes IGBT/D｜ODE loss calculation models, is presented in this paper. Efficiencies of five microgrids with different topologies are calculated and compared under Matlab/ Simulink. At an assumed load power factor of 0.8,the simulation results show that DC microgrid with ring topology has the highest efficiency, however the AC microgrid with tree topology has the lowest efficiency.
