Abstract:
Nowadays, the demand of energy is more and more increasing while the energy resources is decreasing. The main energy resources are exhaustible, i.e. oil, coal and natural gas. Therefore, the renewable energy is one of the alternative way to generate electricity in the future. The most popularity renewable energy is photovoltaic (PV) generation system, that concentrated in this thesis. The main purposes of this thesis are described as follows; (1) Double diode modeling of PV module developed in MATLAB program, which can calculate the current, voltage and power that is generated by the PV module at any condition of solar irradiation and module temperature, (2) study in the shading effect on the PV module by Double diode model of PV, (3) study in mismatch on the PV string by Double diode model of PV, (4) developed PV model in graphic user interface program, (5) study of operating mode of PV grid connection system, i.e. PV mode and PQ mode by considering the 3 parts of PV grid connection system, i.e. DC part, inverter part and AC part considered with load flow calculation. Moreover, this thesis compares the obtained results from the PV modeling with the measured data from the test system to assure that the results are accurate.
