Abstract

This paper presents proportional-plus-integral (PI) controller based frequency regulation of isolated autonomous hybrid distributed generation system for sudden variation in load demand and wind. The developed hybrid system comprises of wind turbine generator (WTG), micro-turbine generator (MTG), fuel cell (FC), an aqua electrolyzer (AE) along with the energy storage device such as battery energy storage system (BESS). Further ultracapacitor (UC) as an alternative energy storage element is incorporated into the system for better performance. The generated hydrogen by an aqua electrolyzer is used as fuel for a fuel cell. The simulation results reported in the paper focused on frequency response for variable wind power, step load change and variable load.
