Abstract :
AESOPS is a well known algorithm for power system eigenvalue calculation. This paper describes a modification to improve the efficiency of the method. The modified algorithm uses sparse techniques to solve the same equivalent network equations of AESOPS in each iteration but, unlike AESOPS, it is an exact Newton-Raphson iteration scheme, and converges significantly faster than AESOPS. Results for a 31 generator power system are described
