Adaptive Wide-Area Control of Power Systems through Dynamic Load Modulating SVCs

This paper presents an adaptive wide-area control strategy based on energy function. The proposed method enhances the post-fault oscillation damping capability of Static Var Compensators (SVC) by incorporating load dynamics in controller design that adapts to variations. are obtained using Phasor Measurement Units (PMU) through power and voltage data measurements, which used estimate a Moving Average (MA) dynamic model. model is then integrated into obtain required SVC supplementary action modulates response disturbance inter-area employing nonlinear Kalman filter PMU measurements. performance evaluated simplified 14 generator southeast Australian system composite models comprised induction motor loads various sizes combinations. results show significant improvements stability when applied.
