Abstract :
A partial energy function is used to quantify the energy of a local transient control action. The function is used to analyze the energy transactions of a single generator in a multimachine power system. This is in contrast with a global energy analysis of the system. Special attention is drawn to an explanation of damping as being caused by tuned control policies. Negative damping is seen as the result of tuned controllers that increase power flows during the backswing more than during the foreswing
