    IMPACT OF HIGH PENETRATION OF SOLAR PV DISTRIBUTED GENERATION ON KARABUK UNIVERSITY LOW VOLTAGE NETWORK
    (2022-06) Al-Gburi, Abbas Falah Hasan
    The installed cost of photovoltaic¬ (PV) systems has reduced over the last years. Such systems can be installed either on land or on the roof as well as floating on water. Today, most integration of PV systems into the power system network is mostly seen on the low voltage distribution network. This inclusion is seen to bring both technological and environmental benefits to the traditional distribution network due to its reduction the pollution, low maintenance, minimization of transmission loss, and stress reduction on the power system. However, high integration brings some negative impacts on the system such as voltage rise, reverse power flow, harmonics, and increased power losses. Therefore, the limits of PV penetration in low voltage networks need to be determined to support the investment and to help the Distribution Network Operators to provide safe and reliable interconnection of PV distributed generation. Karabuk University was taken as a case study in this thesis. Electrical Transient Analyzer Program (ETAP) software was used to simulate the power system of Karabuk University’s electrical network. According to the simulation results, the voltage profile was improved and the feeder losses decreased as the PV penetration increased. The total harmonic distortion was increasing as the PV penetration increased. And finally, we concluded that the PV penetration level at Karabuk university must not exceed 75%.
