With the development of modern power systems, frequency has been an important performance indicator for maintaining the safety and stability of the power system. This paper mainly discusses the anti-disturbance control problem of power systems in finite frequency domain. The main objective is to design controllers in different frequency bands to ensure system stability and reduce the impact of frequency disturbances. The controller design primarily relies on the generalized KYP lemma combined with linear matrix inequalities to obtain controller parameters and conduct simulations. It’s shown that, compared to full-frequency domain control methods, the finite-frequency domain controller exhibits superior control performance within the corresponding frequency ranges.

摘要

With the development of modern power systems, frequency has been an important performance indicator for maintaining the safety and stability of the power system. This paper mainly discusses the anti-disturbance control problem of power systems in finite frequency domain. The main objective is to design controllers in different frequency bands to ensure system stability and reduce the impact of frequency disturbances. The controller design primarily relies on the generalized KYP lemma combined with linear matrix inequalities to obtain controller parameters and conduct simulations. It’s shown that, compared to full-frequency domain control methods, the finite-frequency domain controller exhibits superior control performance within the corresponding frequency ranges.
