Primary and secondary frequency regulation in a longitudinal hydrothermal system by Liapunov method
Electric Power Systems Research, 2008 Abstract The problem of primary and secondary frequency regulation of a multi-machine power system is analysed with a Liapunov function method based on a quadratic performance index. The main purpose is to determine the best set of parameters of primary and secondary regulation according to an optimisation criterion.
