  • Abstract As the popularity of green energy gains momentum, the increase in solar photovoltaic (PV) system power injected into distributed networks is bound to result in voltage standard violation. A study on photovoltaic penetration considering solar irradiance uncertainty is conducted in this thesis to ensure that power quality is within regulatory bounds. The PV unit size with considerable capacity compared with the network size, which consequently affects the penetration level of the solar photovoltaic distributed generation (PVDG), is examined using Monte Carlo to solve a probabilistic power flow (PPF). The PPF accounts for the random nature of solar irradiance and load shape. Therefore, to capture how this randomness affects voltage variation, the PPF is performed at very small time intervals (3.6 seconds) in a quasi-steady state environment. The different penetration levels are statistically compared in order to identify the ideal PV unit size for a test distribution network. This thesis describes the models used for the study, discusses the impacts of PVDG of different penetration level and presents the results of simulations conducted using both MATLAB and OpenDSS software platforms.
