Abstract

Generating power of wind turbine varies in proportion to the cube of wind speed, so they cannot supply constant power and this causes frequency and voltage fluctuations. This paper presents a methodology for controlling grid frequency, hydrogen volume and terminal bus voltage. This system consists of diesel generator, wind turbine and load. Aqua electrolyzer and fuel cell are installed in order to control grid frequency, terminal voltage and hydrogen volume. By applying H_infin control, frequency, voltage fluctuations and hydrogen volume control are achieved. H_infin decentralized controllers are designed and installed for diesel generator, aqua electrolyzer and fuel cell in series. In order to verify the effectiveness of the suggested system, MATLAB/SIMULINK is used for simulations.
