Effects of Solar Irradiance on Load Sharing of Integrated Photovoltaic System with IEEE Standard Bus Network

Abstract

This paper attempts to highlight the effect of change in load and irradiance on Photovoltaic integrated Power system network. The Power system network considered here is IEEE 14 bus system. The simulation is done on MATLAB platform and variation of Voltage, Power and Total Harmonic Distortion (THD) has been studied. The results indicates that how power quality of the power system is affected by the irradiance on Photovoltaic cell. The study is performed considering the other environmental factors such as wind velocity, ambient temperature and humidity have a negligible effect on the photovoltaic module. In a steady-state controlled environment, the simulation results show that the output voltage, current and its power decrease with time as the irradiance on the photovoltaic panel decreases.
