Aim:
The aim of the course is to give the student knowledge about the functionality of a powergrid and the control of its main circuit components.
After completion of the course the student shall be able to:
- describe the main principles of the powergrid and how to control the voltage and frequency through connected generation units and power converters
- describe the functional blocks of a wind turbine system and the associated properties for control
- describe the properties of a pv-system and how to connect to the powergrid
- describe how energy storage is integrated in a pv-system
- describe the function and control of power converters for integration of a generation unit to the power grid
- understand and use models for the main components of a powergrid in system simulation of a power system for energy production.

Course contents:
The course will give knowledge in applications of power electronics, how a power converter operates in a system for energy production as well as the control of the powergrid. Focus is on renewable energy production and its connection and control in a powergrid.
The course has three main blocks:
1. Technology for energy production based on pv, wind and hydro sources.
2. The properties of the powergrid related to stability and availability.
3. Power converter functionality for connection of renewable energy production and control of the powergrid.
In detail, the first block will go through the technology for pv-, wind and hydro power. The properties of pv-cells and how a pv-system is controlled to obtain high efficiency and economy of energy production. Wind power system is described to give basic understanding of different turbine and generator types, including the mechanical and electrical control systems. Difference between sea- and land based wind power systems. Basics for wave, tidal and dam based hydro power systems.
In the second block the power balance between generation and consumption is studied, emphasizing the functions for voltage and frequency control. Needs for energy storage related to day- and seasonal variations in production and consumption.
The functionality and control of power converters for connection of energy production units to the power grid is studied in the third block. Principles for connection of energy storage or supply of isolated loads are presented.
