system to improve the voltage profile and also to meet the reactive power requirements at the
AC–DC terminals to facilitate the smooth operation of DC links. The method involves successive

Description: Frequency control as a major function of automatic generation control is one of the
important control problems in electric power system design and operation, and is
becoming more significant today because of the increasing size, changing structure,
emerging new uncertainties, environmental constraints and the complexity of power
systems.
In the last two decades, many studies have focused on damping control and voltage
stability and the related issues, but there has been much less work on the power
system frequency control analysis and synthesis. While some aspects of frequency
control have been illustrated along with individual chapters, many conferences and
technical papers, a comprehensive and sensible practical explanation of robust frequency
control in a book form is necessary Platform: |
