Teaching language



- Be able to master the modeling of synchronous generators, loads, excitation systems, automatic voltage regulators (AVR), prime movers (hydraulic turbines, thermal steam units) and frequency regulation systems, for dynamic analysis studies. - Be capable of using dynamic simulation software for the purpose of developing transient and dynamic analysis. - Be capable of understanding several dynamic phenomena that arrive during normal and abnormal operating conditions that follows system disturbances. - Understand the operation of Automatic Generation Control in systems with several control areas. - Identify the nature of power system oscillations and characterize such oscillations using modal analysis. Be familiar with power system stabilizers and the procedures for tuning these controllers to increase the damping of electromechanical modes of oscillation. - Understand emergency control actions like load shedding triggered by frequency or voltage (underfrequency and undervoltage). - Be aware of the methodology required to apply automatic learning techniques in order to obtain on-line dynamic security assessment tools.

Learning outcomes and competences

Acquisition of advanced knowledge on mathematical models used to describe the electric power system and their components, to allow the development of stability and dynamic behaviour analysis studies.

Understanding the main dynamic phenomena that can occur in the system.

Identification, project and simulation of control solutions capable to assure a robust operation to the system.

Working method


Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Basic courses about: power systems operation, steady-state and transient analysis of power systems.


- Detailed modeling of synchronous generators, loads, excitation systems and automatic voltage regulators (AVR), prime movers (hydraulic turbines, thermal steam units) and frequency regulation systems, for dynamic analysis studies. - Modeling Automatic Generation Control system and performance analysis in power systems with several control areas. - Modeling and study the dynamic response of the primary and secondary load-frequency control systems following system disturbances (load changes or loss of generation), using simulation software. - Analysis of power system oscillations due to the lack of damping torque at the generators rotors. Study of these phenomena using linearized models of the power system around an operating point and using eigenvalue-based methods. Review of the concepts of eigenvalue analysis of linear systems, addressing the linearizantion of the state equations, the construction of the linear model in the canonic state space form and the physical meaning of eigenvalues, eigenvectors, participation factors, residues and controllability and observability factors. Design of power system damping controllers tackling with the configuration of power system stabilizers (PSS) and the procedures for tuning these PSS. - Description of emergency control actions related with load shedding triggered by frequency or voltage (underfrequency, df/dt and undervoltage). Study of advanced stability enhancement techniques (fast valving, generator tripping, control of shunt and series elements including FACTS devices). - Application of automatic learning techniques in order to provide fast dynamic security assessment of power systems.

Teaching methods and learning activities

Classes will, most of the time, include lectures from the teachers. Two oral presentations are expected from students, reporting conclusions from their oriented study and research in specific domains (2 assignements). In this case, open discussions will be fostered.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Total: 100,00

Amount of time allocated to each course unit

Designation Time (hours)
Estudo autónomo 88,00

Eligibility for exams

Having a minimum grade of 50% in each assignment and also a minimum grade of 50% in the exam

Calculation formula of final grade

The components for student evaluation are: - 2 Assignments - Exam. Each component will receive a grading in percentage. The final score will be calculated according to the following rule: 0,5 * Exam + 0,25* 1st Assignment + 0,25 * 2nd Assignment.

Examinations or Special Assignments

1st Assignment: Overview of advanced techniques for load modeling suitable for dynamic behavior analysis.  2nd Assignment: Study the frequency dynamic behavior of Diesel and Hydro Generators, following system disturbances, using simulation software.

Special assessment (TE, DA, ...)

These students will be subject to all evaluation procedures of regular students, i.e., they must deliver their assignments specified during the course plus any special works also specified plus a final exam, the only difference towards regular students being that they are not required to attend classes and deliver assignments in the same dates as regular students, in the cases the law specifically states it.
