Control for stability in interconnected power systems

The development of a number of stabilizing controls is described. The robustness of the overall power system is emphasized along with modifications to the basic controls necessary to achieve this robustness. Analytical tools used in the design of practical power system controls are described. The importance of validation of modeling and simulation methods by planned system tests and by the analysis of naturally occurring faults is stressed. Likely future system developments are reviewed, including implications for the types of controls that may be necessary.<>
