AbstractModern power systems are complex and non-linear and their operating conditions
can vary over a wide range. In this work, the power system (PS) transient terminal
voltage and frequency stability enhancement have been well investigated and studied
through the following efforts.
• Enhancing the responses of the transient stability by adopting conventional PID
controllers as an additional voltage controller with the Automatic Voltage Regulator
(AVR) in the excitation system for terminal voltage, and in the governing system for
frequency deviation response.
• ANN (NARMA-L2) system is proposed as an effective controller model to achieve the
desired enhancement. This model after training can be called as (Identifier). This
identifier follows the system behavior even in situation of high disturbances.
There are enhancement progress in terminal voltage Vt , and frequency deviation Δω
through the investigation for the three cases (without controller, with PID controller, and
with NN controller) for single machine infinite bus using MATLAB – Simulink software.
