Optimizing photovoltaic model parameters for simulation

Photovoltaic (PV) model is used in simulation study to validate the system design of a PV system. With an accurate PV model for use in circuit orientated software, the behavior of PV array under different environmental conditions can be observed for study. In this paper, the unknown parameters of a single diode PV model are identified using the Particle Swarm Optimization (PSO) approach with log barrier constraint. The proposed method has been applied to a PV module KC65T and has shown accurate modeling result.
