Abstract

Most of the electricity in India comes from fossil-fuels like coal, oil and natural gas. Today the demand of Electricity in India is increasing and is already more than the production of Electricity whereas the reserves of fossil-fuel are depleting every day. There is strong need to shift for other sources and the best option is renewable energy sources. The aim of this project is to design a maximum power point tracking for wind turbine. The maximum power point tracking (MPPT) for wind energy conversation system is used for large and small scale wind turbine systems. The diversity of MPPT methods are developed, these methods vary in implementation, cost, complexity, convergence speed and faster tracking speed. This paper proposes the power characteristics curve of MPPT method in wind power systems. Proposed MPPT is implemented by applying the small-signal analysis on a nonlinear turbine-rotor mechanical system. To verify the performance of the wind turbine system, simulation system is implemented based on MPPT power control. By the variation of wind speed, the behavior of the generator speed presents good consistency among the proposed theory.
