FAQS 4
Does linear ADRC improve power quality in a grid-connected inverter?
In this study, a current control strategy was proposed based on linear ADRC for a grid-connected inverter with an LCL filter to enhance power quality. The proposed strategy handles two issues of active damping and grid voltage-induced distortion through the concept of overall disturbance rejection.
Can ADRC be used in inverter control?
Finally, the adaptability of ADRC in inverter control may be limited, particularly in the face of substantial changes in system dynamics or operating conditions. While ADRC is designed to handle uncertainties and disturbances, its response to sudden load variations or large disturbances may not always meet performance expectations.
How to control a grid-connected inverter?
Some methods of improved ADRC have been proposed to control the grid-connected inverter. In [ 8 ], a nonlinear ADRC controller is provided to control the single-phase inverter. This controller has better immunity performance than PI control, but this control is only suited for the single-phase inverters.
How is ADRC applied to power systems control?
There are several ways in which ADRC has been applied to power systems control, including: frequency and voltage regulation , load flow control , power quality improvement , and marine current turbine disturbances rejection .
