Abstract :
For a single-machine, infinite-bus power system, several digital robust stabilizers with single-rate and multirate sampling schemes are designed using modern H∞ optimization. The digital stabilizers designed have low orders, require considerably slow sampling rates for implementation, and outperform the conventional (analog) power system stabilizer on a series of dynamic performance tests. The importance of weighting functions is stressed in the design process
