TLDR
In this paper, the authors proposed three novel approaches to improve a conventional power system stabilizer (PSS) in a single machine to infinite bus system, which can improve power system stability much more than the conventional PSS which has been used widely in power systems since the 1970s.Abstract:
The authors propose three novel approaches to improve a conventional power system stabilizer (PSS) in a single machine to infinite bus system. These improved stabilizers use the conventional PSS in the usual manner plus modification of the terminal voltage feedback signal to the excitation system as a function of the accelerating power on the unit. This nonlinear action increase the power system stability greatly. Also, since these improved stabilizers are based on the conventional stabilizers, they are simple to implement. Simulation results show that these three kinds of improved stabilizer can improve power system stability much more than the conventional PSS which has been used widely in power systems since the 1970s. >read more
