Patent number: 12007422Abstract: Online estimation of area-level inertia can be used for frequency stability control in low-inertia power systems. This disclosure provides an area-level inertia online estimation method considering inter-area equivalent frequency dynamics. The disclosed method only needs one phasor measurement unit placed at any bus within each area. The inter-area equivalent frequency dynamics model for the multi-area power system is developed, which is employed to estimate area-level inertia under the small disturbance situation. Then, the area-level inertia estimation model boils down to a nonlinear parameter identification problem. The other boundary conditions of the disclosed method are derived by parameter identifiability.Type: GrantFiled: January 11, 2024Date of Patent: June 11, 2024Assignee: NORTH CHINA ELECTRIC POWER UNIVERSITYInventors: Tianshu Bi, Cheng Wang, Jiahao Liu, Guoyi Xu
