    An application of phasor measurement unit to monitor a grid connected solar energy generation system
    (2020) Mahboubi, Meriem; Bentarzi, Hamid; Ouadi, Abderahmane
    While renewable energies are gaining more interest among today’s power sources, solar panels are increasing their contribution to the power grid day by day due to the greatest potential they have. Identical to all other types of power generation plants, the integration of solar energy sources into the grid increases its complexity and poses challenges to maintain the system’s stability. In this paper, an adaptation of a phasor measurement unit (PMU) based solution is proposed for solar plants integration in regular power grids. PMUs can measure the stamped phasors of the utility, which are critical parameters for the operation of power devices feeding power into the grid. This paper discusses the use of PMUs for providing the phase angle to system synchronization in the case of high penetration of solar energy into the grid, where the instantaneous monitoring of the voltage, current and power flow is an important requirement.

    An application of PMU in solar energy generation Plant Connected Power Grid
    (2019) Mahboubi, Meriem; Bentarzi, Hamid; Ouadi, Abderahmane
    Solar energy is one of the most abundant green energies in our planet. In order to satisfy the world demand of electrical energy, solar energy may be used. Identical to all other types of power generation plants, the integration of the solar energy source in power grid has an impact on its operation. Thus, when the electrical power is injected into the power grid by the solar energy source, the system electrical parameters must be well monitored for synchronization purpose. This can be accomplished with the aid of synchro-phasors measurement units. The phase angle of the utility is a critical parameter for the operation of power devices feeding power into the grid like PV inverters. There are many techniques to obtain the grid phase angle such as the zero-crossing detection and the orthogonal phase locked loop. This research work discusses the use of PMUs (Phasor Measurement Unit) for providing this important parameter to system synchronization in the case of high penetration of solar energy in the power grid
