摘要：
This paper proposes a control method for the voltage stability of DC microgrid buses based on a disturbance estimation feedforward compensation strategy, aiming to enhance the dynamic response characteristics of the system. A nonlinear disturbance observer is designed to estimate the load current, and the estimated value is applied to the control loop through the feedforward compensation strategy, effectively mitigating the impact of load disturbances on voltage. To simplify the complex dynamic characteristics of the nonlinear observer, a linear equivalent method is employed. This strategy significantly improves the dynamic regulation performance of the DC bus voltage, ensuring system stability and control accuracy.
