To ensure stable operation of a power system, it is necessary to analyse
the power system performance under various operating conditions.
Analysis includes studies such as power flow and both steady-state and
transient stability. To perform such studies requires knowledge about
the models used to represent the various components that constitute an
integrated power system. In situations where there is a risk of loss of
stability, it is necessary to apply controls that can ensure stable and
uninterrupted supply of electricity following a disturbance.
The subject of stability thus encompasses modelling, computation of load
flow in the transmission grid, stability analysis under both
steady-state and disturbed conditions, and appropriate controls to
enhance stability. All these topics are covered in this book, providing
a comprehensive treatment of the overall subject of stability of power
systems. Topics covered include modelling of the synchronous machine;
the synchronous machine connected to power systems; modelling of
transformers, transmission lines and loads; power flow analysis; optimal
power flow; small signal stability; transient stability; transient
energy function methods; artificial intelligent techniques; power system
stabilizers; series compensation; shunt compensation; compensation
devices; and recent technologies.
The subject matter is covered at a level that is suitable for students,
scientists and engineers involved in the study, design, analysis and
control of power systems.
