| Abstract: | In this paper, the optimal configuration scheme proposed builds an optimization model of AC/DC hybrid distribution network with power electronic transformer (PET). Based on this model, it takes IEEE33 system with PET and distributed power supply as the research object. Taking the minimum loss of system network as the optimization objective, the port volume of PET as the optimization variable, genetic algorithm is used to solve the model. The optimized results of PET port power flow, the total utilization rate of distributed generation, the total power loss of distribution network and voltage level at the end of the system are analyzed. An example results show that the PET has the function for improving power flow distribution of AC/DC distribution network. |
