Microprocessor-based adaptive load-frequency control

An adaptive control strategy for the load-frequency control problem is investigated. The application of self-tuning regulators is suggested as a suitable alternative to the integral control, used normally for load-frequency control. Such a regulator, as implemented on a microprocessor, is described along with test results on a physical model. Adaptive control strategy is found to be very effective in improving the stability and transient response of the system.
