Intelligent Damping Control of Renewable Energy/Hydrogen Energy DC Interconnection System

Abstract

Renewable energy DC hydrogen production has become a new development trend. Due to the interaction between the weak damping of DC network and the negative impedance characteristics of power supply of hydrogen production, the actual available power of renewable and hydrogen energy DC interconnection system will be lower than its rated setting value. To solve this problem, this paper proposes an intelligent damping control to realize the rated power operation of hydrogen generation power source and significantly improve the hydrogen generation performance. In this paper, the nonlinear model under typical control strategies is established in order to adapt to different degrees of disturbance, and the damping controller is designed based on state feedback, including feedback control law and damping generation formula. On this basis, an intelligent method of damping control is proposed to support rapid decision-making. Finally, the intelligent damping control method is verified by simulation analysis. It realizes rated power of power supply of hydrogen production by generating only a small amount of damping power and superimposing it on the hydrogen production power
