Analysis of passivity and disturbance attenuationfor a class of power systems

This paper investigates the dissipative performance of a class of power systems with disturbances, when viewed from a fixed set of inputs and outputs. A passivity result is obtained for a special regulation output, and the Hamilton-Jacobi inequality is solved by means of variable-gradient approach so that the power system has finite L
