Popis: Nowadays, installations supplied by the public grid are adding photovoltaic panels and batteries as complementary source in order to reduce consumption fees. Architectures of such installations are not structured to offer efficient use of renewable generation and storage. This paper suggests an original algorithm that manages available renewable and stored energies in order to guarantee continuous supply of the load, protect the battery against deep discharge and over-charge, and reduce the lost renewable generated energy. Contrary to existent installations, the proposed architecture considers the grid as complementary source and the photovoltaic and stored energies as primary sources. The load is supplied by the grid only in case of non-availability of renewable and stored energies. Such strategy aims to promote the self-consumption in order to reduce as most as possible the energy exchange with the grid. Obtained results confirm that the proposed strategy management ensures a self-consumption rate of 60.5% in stable day and 68% in perturbed day.
