An effective power management strategy for a wind–diesel–hydrogen-based remote area power supply system to meet fluctuating demands under generation uncertainty

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.
