Load Frequency Control power system analysis free pdf download
The electric power system load frequency control ( LFC ) troubles are generated by small load perturbations which continuously disturb the normal operation of power system . Therefore the generation rate of generators has to be change until the frequency and tie-line power maintain close to specified values .
Now a day power systems are split up into numerous areas . The transmission lines that connect an area to its neighboring area are called tie-lines . Power sharing between two areas occurs through these tie-lines .
