Power frequency control in a system of coupled generating units - Conventional versus adaptive approach

Abstract

The application of different types of adaptive control for the power-frequency control of the power-generating system in the Netherlands is considered. Because of the large fluctuations in load, a fixed algorithm in the conventional area controller has some serious disadvantages. In the paper model reference adaptive control (MRAS) is applied in order to deal with variations in the parameter which relates the variations in the frequency to variations in the load. Adaptive control and conventional control are compared. Further improvements have been realized by changing the structure of the conventional power frequency control algorithm and by introducing a feed forward adaptive action. In the simulation numerical values of the power stations in Amsterdam (GEP) and Zeeland (PZEM), which operate within the tie-line system in the Netherlands, have been used.
