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.
