PERFORMANCE MANAGEMENT OF AN INTEGRATED WIND TURBINE-FUEL CELLMICRO TURBINE HYBRID SYSTEM

Document Type : Original Article

Abstract

This paper concerns with the management of the dynamic performance of a wind turbine
integrated with a fuel cell/micro turbine hybrid system for continuous power supply. The objective
is to mitigate some problems associated with the intermittent nature of wind energy and to ensure a
continuous power supply to the load. The strategy is based on maximizing the power extracted
from the wind, where the excess of power is utilized to generate hydrogen through a water
electrolyser. This hydrogen is then used for supplying the fuel cell, which. drives a downstream
micro-turbine. The fuel-cell/micro-turbine hybrid unit is used to provide the deficit power when
the wind power is not enough to meet the load demand. At the same time, it is used to smooth the
oscillatory perhmance of the wind power. This configuration gives more flexibility since the
generated power fiom the fuel cell and micro turbine can be controlled individually. Detailed
models for the wind power source and the hybrid fuel celllmicro turbine system are presented.
Extensive simulation results are introduced to ascertain the feasibility and reliability of the
proposed management approach.
