The ac power stabilizer proposed here has a simple construction and high performance.
Voltage stability is an important factor, which needs to be taken into consideration in order to avoid voltage collapse.
It is found that the proposed PID stabilizer outperforms the traditional power system stabilizer currently used by most power plants.<<ETX>>
The experimental results show better performance of the excitation system with the proposed stabilizer compared to the system with a conventional PI voltage controller and PSS2A stabilizer.
This is in contrast to the case with conventional automatic voltage regulator and power system stabilizer where performance varies widely with the operating situation and can even cause system instability.
Meanwhile, the high voltage, which is more suitable for application, can be obtained.
The model allows for a choice of appropriate voltage stabilizers based on theoretical calculations only and can help to facilitate any experimental study for choosing appropriate voltage stabilizer additives.

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.
Therefore, it is very difficult to design a stabilizer that could present good performance in all operating points of electric power systems.
As a result, a new power system stabilizer which can operate in a wide range of operating conditions and can overcome various disturbances and measurement noises is proposed.
