Stability and control in electric power systems

• Explain the principal causes of voltage, frequency, and rotor angle stability problems in electric power systems
• Describe the different representations of the synchronous machines used for stability studies in electric power systems
• Analyse voltage stability problems in electric power systems using PV curves
• Explain the key concepts for frequency control in electric power systems
• Analyse rotor angle small-signal stability problems in electric power systems and describe means to prevent them
• Describe how the stability problems in electric power systems are affected by grid-related power transfer limitations and generator-related power injection limitations
• Analyse rotor angle transient stability problems and describe means to protect the system against them
• Analyse and explain analytical and simulation results

After a general introduction to the stability problems in electric power systems, the main categories of stability problems are treated, including the mechanisms of instability, countermeasures and theory for analysis. The lectures are complemented by exercise sessions with Python, where study cases are modelled, simulated, and analysed.
