INTRODUCTION technology for the supply of both commodities, which should be One of the major problem in present scenario is power entirely based on renewable sources of energy. The authors, in their previous work, had proposed a design of a hybrid power generation, which is the root cause of depletion of fossil plant which used graphene membrane for power generation fuel. An efficient and effective techno-economic using reverse osmosis process. The proposal included removal renewable power generation techniques is proposed for of arsenic, poorly biodegradable pollutants using TiO 2 trapping energy which is released during the mixing of nanoparticles. Chlorine production using the process of seawater and freshwater. In consideration of centralized electrolysis. The plant was also electronically implemented and and decentralized frameworks for drinking water included pump control, fouling detection modules and decision regulation in the context of risk management theory and module for the volume of effluents to be discharged. The practical challenges. The second most critical problem performance of a power system is essential to be analyzed for control, stabilization and efficient modelling.
