Vlsi based fuzzy logic controller for hybrid renewable energy system

Abstract

Hybrid power systems are combinations of energy conversion devices that newlinewhen incorporated overcome limitations that may be inherent in either Due to their newlinehigh levels of efficiency reliability and long term performance these systems can newlinealso be used as an effective backup solution to the public grid in case of blackouts newlineor weak gridsPower quality surveys indicate the seriousness of the power quality newlineproblems and their economical impact on the consumers and utilities Although newlineinvestigations are in progress in the field of power quality no steps were taken to newlinepredict the power quality problems of power systems This research is proposed to newlineinvestigate the performance of Hybrid Renewable Energy Systems HRES newlinecomprising of Wind Energy Conversion Systems WECS and Photo Voltaic PV newlinesystems Each system individually has been successfully deployed with its own newlinelimitations The unpredictable nature of the renewable sources makes them unsuitable newlinefor providing sustained predictable energy required for grid systems This research newlineproposes to overcome some of the limitations of renewable systems by proposing newlinehybrid energy systems with a common controller newline newline
