Design of a battery-less solar energy storage system based on re-generation of energy

摘要

This paper describes the construction of a battery-less energy storage system designed to facilitate efficient energy provision in rural and under-developed Industrial areas where energy crisis is a major issue. Solar energy is available in abundance during the day and the solar industry focuses on trapping this energy and storing it in form of batteries to drive loads at night. But, taking into consideration the need for cleaner energy practices and also the rising threat from hazardous chemical substances present in batteries and the cost involved behind them in maintenance, makes them obsolete for use in near future. This concept hence focuses on developing a battery-less technique of efficient and optimum storage of the solar energy which is being trapped during the day and providing it at night at a larger output range than the one which is currently being received by existing holistic battery mechanisms. The factors which devise this methodology more solid in terms of efficiency and optimization, are the advanced computational algorithms and control strategies like field oriented control and space vector algorithm for driving the permanent magnet synchronous motor which make the electromechanical system coupled with regeneration of energy, function at higher accurate output ranges.
