Linear Techniques Applied to Small-Signal Electromechanical Stability , Model Order Reduction and Harmonic Studies

This paper describes recent work on small – signal stability, model order reduction and power system harmonic analysis carried out in CEPEL, the Brazilian Electrical Energy Research Center. CEPEL has developed, along the last three decades, a suite of power system analysis tools that are in current use by most of the Brazilian electrical utilities.
