Control strategy of an autonomous desalination unit fed by PV-wind hybrid system without battery storage

الملخص EN

is paper studies the control strategy and state analysis of an autonomous desalination system fed by photovoltaic (PV) and wind generator without battery storage.

Reverse Osmosis (RO) technology is usually used for brackish water desalination to provide fresh water.

The control strategies of the sources are based on power, voltage and current control with Maximum Power Point Tracking (MPPT).

The hybrid source and the RO system are interconnected via a DC link.

The state analysis is necessary in order to expect the behavior of the global system.

The main objective of this study is to control the DC link with the field oriented induction controllers (FOC) method that will be developed for "produce and to purify a maximum of water according to the climatic conditions".

Simulation results are presented to examine the performance of the system and its potentiality in autonomous operati
