This paper introduces a brand-new, inspired optimization algorithm (the chaotic billiards optimization (C-BO) approach) to effectively develop the optimal parameters for fuzzy PID techniques to enhance the dynamic response of the solar–hydrogen drive of an induction motor. This study compares fuzzy-PID-based C-BO regulators to fuzzy PID regulators based on particle swarm optimization (PSO) and PI-based PSO regulators to provide speed control in solar–hydrogen, induction-motor drive systems. The model is implemented to simulate the production and storage of hydrogen while powering an induction-motor drive which provides a great solution for the renewable energy storage problem in the case of solar pumping systems. MATLAB/Simulink 2021a is used to simulate and analyze the entire operation. The laboratory prototype is implemented in real time using a DSP-DS1104 board. Based on the simulation and experimental results, the proposed fuzzy-PID-based C-BO has reduced speed peak overshoot by 45.3% when compared to a fuzzy PID based PSO speed regulator and by 68.13% when compared to a PI-based PSO speed controller in the case of a large-scale motor. Additionally, the proposed speed regulator has a 6.1% faster speed rising time than a fuzzy-PID-based PSO and a 9.5% faster speed rising time than a PI–PSO speed controller. It has an excellent dynamic responsiveness value when compared to the other speed regulators.

“…Except for the decreased cost, scaling up the electrolyzer allows large-scale RES integration, which allows for more efficient use of RES and helps balance intermittent energy generation by converting excess electricity into hydrogen. In [3], Brezak etc. uses MATLAB/Simulink to simulate a PEM electrolyzer operated under various conditions.…”

Water electrolysis systems accelerate the green transition in Danish power, notably via mature alkaline electrolyzers integrated with renewables. The demand for clean and sustainable energy sources has spurred significant interest in electrolysis for hydrogen production. Electrolyzers play a pivotal role in this context, and efforts to scale up their operation are central to meeting the growing hydrogen demand. This study develops MATLAB/Simulink models of varioussized alkaline electrolyzers to design large hydrogen plants, assessing their scalability and economic viability.

This study presents the first work that investigates a preliminary design generating hydrogen from the wastewater of coal utility boilers via an integrated photovoltaic (PV)−electrolysis system. Connecting solar panels, which generates electricity, to an electrolyzer to split water molecules to hydrogen and oxygen is an attractive method to generate hydrogen. A numerical model is developed for the integrated PV solar panels and polymer electrolyte membrane (PEM) electrolyzer. Parallel solar panels and series PEM electrolyzer cells are considered in the present work to reach the optimum arrangement. The essential losses including the activation and ohmic overpotentials and the required energy for rotary equipment (compressors and pumps) are considered in the model. The effect of the working temperature, solar irradiation, and charge transfer coefficient on the efficiency of the system is investigated. The calculated efficiency of the PEM electrolyzer and PV solar panels is in the range of 60−62.5% and 18−20%, respectively. The efficiency of the integrated PV electrolyzer increases as solar irradiation increases. Of particular interest is the potential application of the present design in Texas, which generates 1.43 × 10 4 Nm 3 /year of green hydrogen for $4.67/kg H 2 by only scaling up by 11. This model provides valuable insights for the large-scale hydrogen generation from power plants' wastewater via the coupled solar energy and electrolysis system.
