Practical Applications of the Energy Function Method

Abstract

In the previous chapters we have discussed the theoretical aspects of energy function analysis of power systems. These were basically (i) motivation for energy function analysis through equal area criterion, (ii) internal node and structure preserving energy functions, (iii) reduced order energy functions, (iv) energy functions for detailed models, and, finally, (v) the characterization of the stability region of the post-fault stable equilibrium point and justification of the PEBS method. It is fair to say that in the power system stability area theory has sometimes tended to be ahead of practical applications. The final aim of any theoretical advance is the possibility for application for real world systems.
