Abstract :
This paper describes a simple but efficient modification to improve the well known PEALS/AESOPS algorithm for power system eigenvalue calculation. The modified algorithm is a Newton-Raphson iteration scheme which converges significantly faster than AESOPS. The algorithm is linked to the operational transfer matrix equation method. An efficient operational matrix based formula is suggested to calculate the sensitivity of an electromechanical eigenvalue with respect to the transfer function of a power system stabilizer. Results for a 21 generator power system are described
