Solar thermal-wind-spring storage hybridized system for steady power yield

This paper presents a steady power producing unconventional hybrid scheme of combined vertical axis wind turbine and solar thermal run Stirling engine with a spring storage system. This eccentric scheme will substantially alleviate the prominent drawbacks associated with most of the prevalent solar-wind hybrid power plants. In the proposed plant, a hybrid vertical axis wind turbine exploits wind energy at both low and high speed, a specially designed sphere of Fresnel lens captures the solar energy, Stirling engine utilizes the entrapped energy for solar power generation and a spiral torsion spring stores the surplus energy in the plant. Modelling and simulation of the plant has been done and in the simulated result, a steady power of 1.3 kW is observed at the generator shaft due to the contribution of any of the primary sources and storage system.
