Energy optimization for a photovoltaic/thermal desalination plant
Renewable Energy based systems cannot effective without control. In this paper, Fuzzy Logic Controller which aims to ameliorate the PV/T based RO process performance is proposed. The conceived control is based on varying the flow rate of the circulated coolant fluid according to feed water temperature and Photovoltaic cells temperature. Obtained results which are based on simulation using LABVIEW software prove the effectiveness of the proposed controller. Measurements show an increase on the RO unit productivity while protecting the RO membrane from overheating problem. Additionally, electric efficiency of PV/T collectors is ameliorated due to the coolant fluid circulation. Besides, permeate salinity is maintained in the standards.
