Intermittent energy sources are sources of renewable energy production corresponding to natural flows, which are not permanently available and whose availability varies greatly without the possibility of control; like solar power and wind power, and for this reason; the use of traditional sources such as diesel generators remains important. Hybrid systems operating in isolated or autonomous mode in Algeria are not only intended to provide energy, but are also a tool for socio-economic development in rural areas. The intention of this thesis is to present an experimental study of an isolated hybrid system (photovoltaic and wind power with storage battery) installed in Constantine-Algeria, to meet the demand for energy used in public lighting (2000Wh / day for a test period, during the months of March and April 2018). And to meet a demand for a residential house (6000Wh / day, during the months of May, June and July 2018). This study examines a new strategy for how the MPPT charge controller (FLEX max60) controls the energy stored in solar batteries, by increasing the number of hours of absorption phase (ABS). In order to reduce the use of traditional sources. The control strategy was implemented on an experimental basis and the results presented showed the feasibility of the hybrid system, whatever the weather conditions. Therefore, maximum power point tracking (MPPT) has been proven to recharge efficiency, qualitatively and quantitatively in the MPPT controller (FLEX max60).
