In this paper, a single stage buck-boost inverter is proposed for grid connected PV system with a very high voltage gain. The proposed inverter not only boosts DC output voltage of the PV module but also converts it into AC voltage which is required for grid connection. Discontinuous conduction mode (DCM) is employed to achieve unity power factor with the grid voltage and a maximum power point tracking...
In terms of optimal Microgrid (MG) control, the output power of a non-dispatchable Distributed Generation (DG) as a Photovoltaic (PV) system need to be controlled based on the optimal operating condition of its primary energy source by the mean of a Maximum Power Point Tracking (MPPT) to extract the potential maximum power which is nonlinearly depending on the weather conditions. In this work we presented...
In this article, a new control algorithm of MPPT (maximum power point tracking) is proposed. The proposed algorithm takes the interaction between solar arrays, photovoltaic inverter, MPPT control, dc side dynamic model of solar arrays and the light intensity of the solar arrays into consideration. The algorithm is based on Lyapunov model reference adaptive control (MRAC). The algorithm provides a...
