Controller design of isolated power-electricity island using genetic algorithm

Ivan Sekaj – Martin Ernek

   The contribution presents the use of Genetic Algorithm for searching of the optimal parameters of a set of speed controllers of an isolated power-electricity island. The island consists of several hydro turbine-generators and CCGT blocks in speed control mode and a nuclear power plant block in power control mode. Nine PI-controllers are designed. The cost function which is minimised using the Genetic Algorithm represents the integral of the control error area. Robustness aspects of the control design are considered as well.
