This paper addresses power management strategies,
including technical issues and control methodologies, for a winddominated
hybrid remote area power supply (RAPS) system.
The system consists of a doubly fed induction generator, a diesel
generator, a hydrogen-based generation scheme, and mains loads.
The goal is to maximize power extraction from the wind generator
under generation uncertainty. For active power management, a
hydrogen-based generation scheme consisting of an electrolyser
and a fuel cell system is integrated to the RAPS system. Developed
control strategies contribute to achieve the following objectives:
1) load side voltage and frequency regulation; 2) maximum power
extraction from wind; and 3) regulating diesel generator operation
at low load conditions. Simulation studies with a real-life data
set are used to evaluate the proposed architecture and prove the
control objectives, and it has been observed that all the proposed
objectives are met within satisfactory limits.
