Converters analysis and simulation in microgrid

In recent years, with the depletion of fossil fuels and the deterioration of the environment, in order to meet the demand for energy, the reform of traditional energy structure is imperative. Therefore, renewable energy such as wind energy and solar energy has been vigorously developed. The interface between the DC bus and the grid in the PV system requires an intermediate power electronics bridge to convert the electrical energy into the corresponding voltage level and type. As the Grid-connected inverter is the most important interface device, it has direct impact on the PV generation system and the operation of the network. In this project, the three-phase grid-connected inverter system and the PV generation system have been modeled. 
 In this project, I will analyze multiple types converter in microgrid including single/three phase rectifier, single/three phase inverter and four types of converter. The main part of this project is introduce operating principles about each power converters. The numerical example will also be given to show the design steps. After the analysis, the simulation will be achieved in MATLAB/Simulink.
