EEEN40550 Power System Dynamics and Control

Academic Year 2022/2023

The module presents dynamic models and controll schemes of the most important devices that compose a power system network. These include the synchronous machine, transformers, power electronic devices and induction machines. For each device a detailed description of its dynamic behavior and control strategies are presented. Both theoretical aspects
and simulation‐based examples are discussed. The contents of the module is the following.
1. Dynamic model of the synchronous machine. Synchronous machine primary and secondary controls including automatic voltage regulators, turbine and turbine governors, under and over‐excitation limiters, and power system stabilizers. Synchronous machine secondary controls including automatic generator controllers and secondary voltage regulators. Tertiary frequency control.
2. Transformer dynamic model and controllers including under-load tap-changers and phase shifters.
3. VSC model and controls. Control of shunt and series FACTS devices.
4. Induction machine dynamic model. Speed control of induction motors.
5. Distributed energy sources control with particular emphasis on models and controllers of wind turbines and photovoltaic panels (MPPT, voltage control, frequency control, etc.).
