AI Technical Summary

Technical Problem

Power systems with numerous complex components, such as electrolysis plants for hydrogen production, are difficult to control precisely, posing safety risks due to intricate interactions and deviations from control models, especially with model predictive control, which makes assessing control accuracy challenging before and during operation.

Method used

Implement a control method that switches between non-model-based and model predictive control modes based on switching criteria, using an estimation module to evaluate control performance and ensure safe operation by transitioning to model predictive control only when sufficient accuracy is guaranteed.

Benefits of technology

Ensures safe operation with over-safety in non-model-based control while enabling high efficiency in model predictive control, allowing continuous monitoring and seamless transitions between control modes, and adapting to component changes through modular estimation.

Abstract

The invention relates to a method for operating a power device (3), wherein: - in a first control mode, the power device (3) is controlled by means of non-model-based control; - in a second control mode, the power device (3) is controlled by means of model-predictive control; - switching between the first control mode and the second control mode is carried out on the basis of at least one switchover criterion; - in both control modes, system values (33) of the power device (3) are transferred to an estimation module (27) which is based on the model on which the model-predictive control is based, the system values (33) comprising at least measured values (41) measured at the power device (3); - control quality of the model-predictive control is evaluated by means of the estimation module (27) on the basis of the system values (33); - the at least one switchover criterion comprises the evaluation of the control quality; - at least in the second control mode, a state (35) of the power device (3) is estimated by the estimation module (27) on the basis of the system values (33); and - in the second control mode, the power device (3) is operated by means of the model-predictive control on the basis of the estimated state (35).
