At present, Thailand electricity is mostly generated by using natural gas, which accounts approximately for 65% of total electricity production. However, the amount of reserved natural gas is limited. Since renewable energy is one of the highly potential alternatives to generate electricity in the future, this thesis proposes the modeling of photovoltaic (PV) generation system. The three main components of thesis are as follows; (1) the modeling of a PV module developed by MATLAB program, in which the PV module parameters, i.e. current, voltage and real power, can be calculated by using data provided in commercial datasheet of PV module manufacturers, (2) the study of operation modes for PV grid connected system, which consists of PQ and PV modes and requires the three electrical modeling parts, i.e. DC part, inverter part and AC part that is integrated with load flow calculation, and (3) the study of shading effect of PV modules. Moreover, this thesis shows the comparison between the results from the PV module modeling and the measured data from a real PV system to confirm the accuracy of the developed modeling.
