The new strategy of energy management for a photovoltaic system without extra intended for remote-housing

• The core strength of the new management is the predictive control of washing machine according to SOC at 23h55.
• The traditional architecture allow us to add the control aspect of lighting and the fan, all respecting the comfort.
• The optimized management of load has resulted in the minimization of LPSP and storage use.
• A real investigation was done on electricity consumption in a desert regions.
• The first experimental SAPS without load management installed in Ghardaia site is used for this study.

This paper proposes a new strategy used to optimize the demand side management for a stand-alone photovoltaic system (SAPS) without ancillary source in desert regions. It is based on developed load profile, actual weather conditions and energy storage. The intended objectives are house energy comfort and economic size of the system. The first objective was achieved by reducing the loss power supply probability (LPSP), which leads to the reduction of load shedding. The second objective is attained by reducing the batteries replacement through the improvement of the life cycle of batteries. The size of an experimental SAPS without load management was used for case study.
