Practical Course to Power System Operation, Control, Stability, and Optimization

Course Description

This course covers all aspects of power system operation and control, beginning with the analysis of power system stability, progressing to voltage and frequency regulation, and concluding with the development of an optimal economic power network.

The course consists of 15 chapters and 130 lectures with a duration of 16 hours.

The course is structured as follows:

Initially, an overview of power system stability is presented through the following topics:

1. What is power system stability?
2. Types of disturbances affecting the power system
3. Power system stability classification
4. Rotor angle stability
5. Frequency stability
6. Voltage stability

The swing equation, the central equation for transients in power systems, will be covered in the following section. Here are the subjects that will be discussed:

1. Synchronous machine modelling
2. Types of synchronous machines
3. Machine reactances during transients.
4. What is rotor angle?
5. Swing equation analysis
6. Accelerating torque.

Further on, we’ll go over the Single Machine Infinite Bus System (SMIB), a crucial component of power system research. Here are the subjects that will be discussed:

1. Classical model for stability studies
2. Power angle curve
3. SMIB before faults
4. SMIB during faults
5. SMIB after faults

After that, you will have a thorough understanding of SSSA, or Small Signal Stability Analysis. Here are the subjects that will be discussed:

1. Damping power
2. Linearization of swing equation
