Research on Automatic Active Disturbance Rejection Control Method for Hydrogen Production by Alkaline Electrolysis of Green Electricity

Green electrolysis of water for hydrogen production has a very wide application prospect because of its ability to utilize renewable energy to produce hydrogen. However, in the process of hydrogen production by green power, the temperature at the working point of the system fluctuates continuously due to the strong volatility of renewable energy, so a linear self-resistant controller (LADRC) based on the Nash Equilibrium Quantum Particle Swarm (NEQPSO) algorithm is proposed. First, the temperature control process of the green power hydrogen production system is analyzed, and the LADRC control method is proposed for the perturbations in the process. Second, the Nash equilibrium is integrated into the quantum particle swarm algorithm to optimize the parameters of the linear self-oscillating controller, and the optimized parameters are applied to the control system. The results of the simulation indicate that the overshoot of the LADRC method by 10.39% was reduced due to the perturbation. The rapidity also improved by 17.60%, demonstrating a favorable control effect.
