SIMULTANEOUS STABILIZATION OF POWER-SYSTEMS USING GENETIC ALGORITHMS

The paper considers the simultaneous stabilisation of a power system o ver a wide range of operating conditions via a single power system sta biliser using genetic algorithms. The power system operating at variou s loading is treated as a finite set of plants. The problem of selecti ng the parameters of a power system stabiliser which simultaneously st abilises this set of plants is converted to a simple optimisation prob lem which is solved by a genetic algorithm and an eigenvalue-based obj ective function. A single-machine infinite bus system is considered to demonstrate the suggested technique.
