Abstract:
Due to the increasing concern about the environment and the depletion of natural resources such as fossil fuels, much research is now focused on obtaining new environ mentally friendly sources of power. To preserve our planet for the future generations, natural renewable sources are being closely studied and harvested for our energy needs. Wind energy is environmentally friendly, inexhaustible, safe, and capable of supplying substantial amounts of power. However, due to wind's erratic nature, intelligent control strategies must be implemented to harvest as much potential wind energy as possible while it is available. Because of its advantages, erratic nature, and recent technological advancements in wind turbine aerodynamics and power electronic interfaces, wind energy is considered to be an excellent supplementary energy source. Research to extract the maximum power out of wind energy is an essential part of making wind energy much more viable and attractive.
This report is an analysis on maximum power pint tracker of wind turbine, conversion principle of wind energy, wind energy conversion technology, various configuration of wind turbine used to harness the wind energy, type of generators that could be used with their merits and demerit, power electronics devices interfacing. Grid connection of renewable energy sources is essential if they are to be effectively exploited. Two different power electronics devices (PWM and matrix converter) had been interfaced to the grid and Peak power point tracking Algorithm has been implemented to get the optimum energy available all the time .A case study also been done for fixed speed wind energy conversion system without having the tracker and for variable speed WECS having the Peak power point tracker. Results are tabulated and compared
