    ANALYSIS AND ENHANCEMENT OF THE DISTRIBUTION NETWORK BY SHARING RENEWABLE ENERGY
    (2023-02) Al-Nuaimi, Omar Mohammed Raheem
    Iraq's electricity generation in general depends on natural gas, fossil fuels, and oil that accounts about 97%. In accord with the International Energy Agency, the electricity generation increased from 64.75 TWh in 2015 to 97.26 TWh in 2021. With an annual population increase of more than one million people, the electricity demand for Iraq is expected to increase double between now and 2030. There is a significant gap in distribution network system of Iraq, including interruptions and the daily shortages of electricity. Iraq has enormous potential of renewable energy resources and can significantly increase the portion of them in the producing electricity. The penetration of renewable energy to distribution network systems with its advantages has also drawbacks. Renewable energies exhibit power fluctuation, high nonlinearities, changing dynamics, and uncertainties. Therefore, it is required to provide a stable operation and reliability of the power system while integrating renewable energy into the distribution network of the utility grid. In this master thesis, a study of a low voltage distribution network operation using renewable energy is considered for 11 kV feeder with 3.5 MW load of Baghdad city. Electric Transient Analysis Program (ETAP) is applied to analyse a distribution network including such parameters as load flow, drop voltage, power losses, harmonic analysis, and active power. The distribution network analysis process is executed to evaluate the state and operation of existing system under various load operating cases. Simulation’s results in ETAP show that using PV energy can reduce overload and power losses in a distribution network.
