Abstract

The paper deals with the modelling of the power stations and the interconnected power systems for the design of the load-frequency controller of the Hungarian power system. It presents an adaptive regulator which uses the a priori known information and satisfies the multi-objective character of the control. The elaborated control strategy performs the following objectives: •-It eliminates the effect of the area load fluctuations to the tie-line power. •-It guarantees the scheduled value of the exported/imported energy. •-It reduces the commands sent to power stations. •-It satisfies the requirement with minimum cost. The paper shows the real-time experiments with the implemented adaptive regulator which is presently applied for the load-frequency control of the Hungarian power system.
