Abstract :
This paper recommends an optimal sizing model, to optimize the capacity sizes of different components of photovoltaic water pumping
system (PWPS) using water tank storage. The recommended model takes into account the submodels of the pumping system and uses
two optimization criteria, the loss of power supply probability (LPSP) concept for the reliability and the life cycle cost (LCC) for the
economic evaluation.
With this presented model, the sizing optimization of photovoltaic pumping system can be achieved technically and economically
according to the system reliability requirements. The methodology adopted proposes various procedures based on the water consumption
profiles, total head, tank capacity and photovoltaic array peak power. A case study is conducted to analyze one photovoltaic pumping
project, which is designed to supply drinking water in remote and scattered small villages situated in Ghardaia, Algeria (32 290N,
3 400E, 450 m).
