## Abstract

The feasibility of applying optimal control to excitation of a synchronous generator is examined by simulation using a single machine connected through line reactor to an infinite busbar. The gains of the optimal regulator satisfy a simple quadratic cost function. These are dependent on a Q weighting matrix. The engineers always use a trial and error method to determine a Q matrix in conventional optimisation. In this paper a genetic algorithms (GA) calculation is proposed to design a Q weighting matrix. The voltage and frequency responses by conventional optimal control and GA optimal control were compared. The combination of genetic algorithms calculations and optimal control feedback can greatly improve the performance of power system single machine area.
