Abstract
With the development of new energy power generation technology, more and more regions are increasing the construction of new energy power generation facilities. However, due to the unstable factors in the source of new energy, the traditional modeling methods require a lot of work. Modeling the impedance of the system in a d-q frames has become a new option, but there is no reference for the derivation process of the system impedance, control model and mathematical model. In order to reduce the amount of tasks of more complex impedance modeling, this paper correspond the control model and mathematical model of Grid-connected inverters in Matlab/Simulink. Among them, the most important part of the control model is the model building of PLL, which includes power control and current control.
