ECTS: 3

Description:

The course will provide training and education in the field of stability theory, stability of modern electric power systems with synchronous generators, power electronics-interfaced renewable generators, and other power electronic systems, such as HVDC and Flexible ac transmission systems (FACTs). 

The PhD course will cover basic knowledge of stability theory, electrical power system stability, impacts of power electronic conversion system, electrical machines and renewable energy generators on the system stability, especially, the stability under the large scale integration of renewable generators and significant reduction of conventional synchronous generators. 

Some of the course contents are based on recently obtained research results 

The main topics are as follows:

• Overview of power system stability and classification
• Basics of stability theory
• Frequency stability of power systems
• Voltage stability of power systems
• Multi-time scale and quasi steady state simulation
• Frequency response and regulation of renewable energy plants
• Small signal stability and analysis method
• Large signal stability and analysis method
• Sub-synchronous oscillation
• Stability of power electronic dominated power systems
