Study On The Optimization Design Of Seawater Reverse Osmosis Power-supplied By PV And W/G

Survival and development of human society cannot come true without twoimportant conditions—water and energy. However, only3%of the overall waterresources on our planet is available for human beings,25%of the world’s populationare unable to drink enough fresh water. Meanwhile, with global warming, drought anddesert increases, increase in the number of population, the growing problem ofenvironmental population and so on, less and less fresh water resources currentlyavailable while the demand of water is increasing. China is seriously lack of fresh waterresources. Since seawater is inexhaustible to obtain, getting a lot of long-time storage offresh water in a low cost is an important means to address the shortage of waterresources. However, desalination is energy-intensive industries. Along with thetraditional energy shortage problem has become increasingly prominent, renewableenergy has been widespread concern, including solar and wind power technology hasgradually matured. The use of wind and solar energy supply for the seawaterdesalination provides an effective way to solve the water and at the same timetraditional energy crisis.This paper first reviews the utilization of new energy sources in the field ofdesalination, the quo of wind and solar research and development, the trend of thepower generation system of desalination equipment. The wind and solar power-supplieddesalination project which is based of mature sub-technology has been proposed.Then the complete system divided into two major modules is introduced in detail,namely the module of wind and solar power and desalination module. The compositionand working principle of complete power hybrid reverse osmosis seawater desalinationsystem have been discussed.Most attractively, this project choose Lin Gang, Shanghai, as the object, for its verylarge area and affluent wind resource. Considering the distribution of wind and solarenergy, the hybrid desalination system is designed and simulated. In the end, the suitable match program is optimized with a simple local optimization method.Finally in line with the introduction of complementary scenery genetic algorithmsto this system, the whole life-cycle cost has to be the objective function in the wholestate space of the system to calculate the optimal matching scheme.Because wind and solar power-supplied reverse osmosis desalination device is verycomplex and affected aspects are too much, this study complete a serial ofcomputational and simulation method for the design of such a system, including itsoptimization using genetic algorithms in theory. A deeper reflection and exploration onsystem design and dynamic optimization as well as some principles for design havebeen proposed and summed up.
