Microprocessor-based Load Frequency Self-Tuning Regulator for a Micromachine

ABSTRACT

In previous paper, the authors proposed a new method of designing load frequency self-tuning regulator for interconnected power systems with unknown deter-ministic load disturbances and demonstrated the effectiveness of the controller using digital computer simulations.In this paper, we acidify the discussion of the earlier paper by defining a new cost function and derive a more new self-tuning regulator. The proposed regulator is then used to control the frequency deviation and the tie-line power deviation of one area, modelled by a laboratory micro-machine connected to a large system. The experimental results show that this regulator can act satisfactorily for improving dynamic responses of the load frequency control.
