Disturbance approximation based frequency control

Frequency control in power networks is one of the most significant problems. Frequency is an indicator of power balance in power network and any imbalance leads to frequency deviations from the nominal value (50 Hz), which can lead to equipment damage or complete power network shutdown. A new frequency control scheme based on the disturbance approximation is presented in this work. Numerical experiments show that the developed control scheme is more effective than the one currently used as it provides better frequency convergence to the nominal value in the case of an imbalance.
