Optimum operation planning for a PVG/Battery standalone installation

The electrification of rural areas by autonomous renewable energy generators becomes attractive as it has good effect on people lifecycle. So far, the Photovoltaic Generator (PVG) associated to storage bank is widely used to cover loads’ need during the whole day. Nevertheless, many energy supply issues may appear following weather perturbation. In this paper, an algorithm is proposed to plan the basic loads operation, via relays unit, of a PVG/battery based installation namely: cold room, light and water pump. Planification is mainly based on the PVG generation forecast. The algorithm ensures a continuous operation for the cold room then plans the rest of generated energy for lighting and pumping with respect to optimization criteria: maximum use of available energy and battery safety. Obtained results confirm the respect of the prefixed criteria: no lost energy and the battery protection.
