Dynamic Performance Evaluation of a Computer Controlled Electric Power System

The paper presents the general dynamic evaluation problem of an Electric Power System under computer control. The philosophy and design techniques of a state-of-the-art digital load- frequency controller are outlined. Dynamic control criteria which will allow performance evaluation of this class of control are defined. Techniques of applying these criteria are presented, along with consideration of man-machine requirements for their evaluation. A trend recording technique suitable for performance evaluation with a control computer is described. Finally, simulation results and field test data are presented to illustrate dynamic performance evaluation of a controlled system.
