The joint simulation of a stand-alone photovoltaic system based on PSIM and Matlab

There are many software can be carried out simulation of photovoltaic (PV) system such as PSIM and Matlab. Those software have their own advantages in the simulation of PV system. This paper proposed a joint-simulation of a stand-alone PV system based on PSIM and Matlab to achieve the maximum power point tracking (MPPT) of PV cells and the stability of PV system. In this paper, the main circuit is built in PSIM and the control circuit is built in Matlab. The results of simulation show that the method can make PSIM and Matlab give full play to their advantages in power conversion and control algorithm.
