Energy transfer mechanism for a grid-connected residential PV system within the Matlab/Simulink environment

Categorized as one of the renewable energies, photovoltaic (PV) system has a great potential compared to its counterparts of renewable energies. Such systems can be either stand-alone or connected to utility grid, while alternative energy sources besides providing power to their local loads. In order to show the interaction between different parameters of the PV grid connected system, the dynamic energy transfer behaviour of the system should be investigated. In this paper, a study of the energy transfer mechanism for a grid-connected photovoltaic system within the Matlab/Simulink environment is presented; taking the domestic load as a local load drawing the energy either from the photovoltaic source or from the utility grid.
