A smart single stage solar battery driven desalination system with hybrid MPPT and optimal control for brackish water treatment.

ABSTRACT: Reverse Osmosis (RO) desalination systems powered by renewable energy provide a practical solution for fresh drinking water in remote off-grid communities. However, RO desalination is an energy-intensive process that requires a stable and efficient power supply. This paper presents a high-performance, single-stage PV-RO desalination system with battery storage. A SHO-P&O MPPT algorithm optimizes PV power extraction, minimizes voltage fluctuations and ensures stable operation under fluctuating solar conditions. To enhance system efficiency, a Quasi-Z Source Inverter (QZSI) is integrated to improve energy conversion, eliminating the need for a separate DC-DC boost stage. Additionally, the RO system is modeled as a Two-Input-Two-Output (TITO) system, where precise regulation of the permeate f
