Reactive power compensation of a solar integrated utility grid through real power as a function of power factor method

Abstract

Due to the depletion of conventional resources and increased demand in electrical power focus is shifted towards the renewable energy sources. This paper proposes the solar photo voltaic system interconnected with the utility grid with a two-stage conversion system. The control of real and reactive power and utilization of the solar electricity to the maximum quantity is maximum challenging element when photo voltaic system is connected to the utility grid and additionally controlling of reactive power is maximum complicated hassle for the researchers. In this paper reactive power compensation is done by using the inverter control rather than FACTS devices due to the disadvantages of these devices. To track the maximum power, MPPT technique with incremental conductance method is used. The inverter controller controls the real and reactive power from the solar panel depending on irradiance. The proposed methodology controls the power factor as a function of real power. Entire project is done in MATLAB software.
