Abstract
In this paper, modeling of one type of grid connected single phase inverter commercially available in Thailand is carried out. An inverter of a grid-connected photovoltaic system has been tested and its model determined. The inverter operates in transient conditions and its modeling is done using nonlinear system identification approach with Hammerstein Wiener Model. The models in transient conditions which compose of power step up and step down condition have been experimented. The results comparison on modeling of transient condition using Hammerstein-Wiener Model has been analyzed by system identification process. The accuracy of waveform from the system identification between experimental and validate data in both transient conditions are 91.75%, 85.99% respectively. The mathematical model being the representation of the system can be analyzed and provide characteristics on controllability, stability, power quality, power flow in such condition.
