Abstract:The goal of this paper is to develop and validate a novel power control strategy allowing to operate a Brackish Water Reverse Osmosis (BWRO) desalination test bench properly using isolated hybrid (PV/Wind) renewable sources without batteries. The proposed strategy uses Power Field Oriented Control (PFOC) in order to maintain DC bus voltage stability and to ensure power transfer from electrical sources to hydro-mechanical loads under variable power generation conditions. Experimental performances have been tested in different operating modes while respecting a Safe Operating Window (SOW) for desalination process. Power sharing is ensured by a basic Energy Management System (EMS).
Keywords:PV/Wind hybrid system  Reverse osmosis desalination  Power field oriented control  Experimental tests  Without battery
