Energy Efficiency Analysis for Wind/Photovoltaic Hybrid Seawater Desalination System

Abstract

The data of wind/photovoltaic hybrid power generation, battery power supply, and power consumption of seawater desalination system under off-grid was analyzed by using the test platform with a design capacity of 1m3 per day. The energy supply, conversion process, and energy efficiency of wind/photovoltaic hybrid were analyzed according to the result. The experimental results showed that the established model and the energy control strategy ensured the steady operation of the seawater desalination system. When compared to the single battery power supply, the utilization ratio of the energy of the system was 16% higher with improved economic benefits.
