Performance of hybrid wind-microturbine generation system in isolated mode

Abstract

The energy demands increment, perishing resources of fossil fuels and growing pollution levels encourage more electricity generation using renewable energy sources such as wind, solar, geothermal, tidal etc. Generation of electricity using high speed wind seems a viable and environment friendly solution to meet energy crisis. However, due to variable nature of wind speed, it is difficult to supply constant power demands. In this paper, a hybrid energy generation using combination of wind turbine driven generator and Permanent Magnet Synchronous Generator (PMSG) driven by microturbine has been proposed, which is quite effective in supplying constant power loads. The two generation systems have been interfaced by power electronic interface. A simulation model of the hybrid generation system has been designed using MATLAB/SIMULINK and its various characteristics have been observed.
