Hybrid Dynamic Modeling and MPPT Control for Photovoltaic Power Generation System

Photovoltaic power generation system had been paid more and more attention. Photovoltaic power generation system was a nonlinear system, which was decided by the nonlinear characteristic of photovoltaic cell and power electronic device. In this paper, according these nonlinear characteristic, hybrid system theory was discussed in the MPPT of photovoltaic system, photovoltaic energy converter MLD (Mixed Logic Dynamic) model was given, and, the predictive controller is designed based on the model. At last, the simulation results verified the validity of the model and the effectiveness of the proposed controller.
