The increased loading of power system transmission lines and equipment is resulting in operation closer to the stability limits of the system. As a result, there is increasing concern over the secure operation of power systems all over the world.



This course will provide a comprehensive overview of fundamental concepts on voltage stability, such as the significance of reactive power management and voltage control. Modelling and analysis techniques to identify potential voltage stability problems and solutions during the planning, design, and operation of power systems will also be presented. The course will also cover in detail various technologies available today to prevent voltage stability on power systems, including static var compensators and inverter-based dynamic compensators. Case studies of actual voltage instability problems and equipment solutions will also be presented. The impact of wind generation on system voltage stability, interconnect requirements, reactive power and voltage control equipment solutions will also be covered. In addition, sustainable power generation will be addressed.

Practical examples will be provided to show the operation control of the presented techniques and their effect on the power system.

At the end of this course, participants will be able to:

• Understanding power system stability problems and their classification. 

• Understanding modeling requirements of power system equipment for different studies. 

• Understanding causes of instability and methods of analysis and enhancement of different power system small and large disturbance rotor angle stability phenomena. 

• Understanding different methods and techniques of power system stability controls and their limitations. 

• Using computer packages for analysis of power system stability problems.

• Comprehend different sustainable power generation techniques.
