In order to suppress the low-frequency oscillation of the power system due to negative damping and improve the stability of the power system, a Hybrid Power System Adaptive Adaptive Stabilizer (GPSS) is designed. Unlike traditional designs, it includes several adaptive GPSS, and these stabilizers work in parallel at the same time. The stable control signal is obtained from each single adaptive GPSS weighting, and at the same time, the choice of weighting coefficient is studied. Both theoretical analysis and simulation results show that the proposed scheme has significant effect on suppressing the low frequency oscillation of power system, improving the operation quality of power grid and ensuring reliable and high-quality power supply.
