Content and learning outcomes

Course contents

You will apply your electrical engineering skills on fields that are of relevance in the field that is called'intelligent electrical power grids'. You will also be acquainted with basic concepts in innovation and enterprise around technical innovations in this field.

Module 1 and Project 1
Intelligent Electric Power Grids as general concepts

Module 2 and Project 2
Power generation from renewable energy sources. Analysis of the effect of the power grid on: electricity production on all voltage and power levels, increased part distributed generation, higher part fluctuating energy sources e g wind and sea-wave power. Principles for energy storage and transformation between energy forms e g batteries, flywheels, compressed air etc The flexible distribution system. Effect of large-scale renewable generation, improvement of energy efficiency in large-scale facilities, new components in the distribution system.

Module 3 and Project 3
Intelligent power grids on consumer level. Effect of IT and communication solutions. Effect on own generation, optimised electricity usage, electric vehicles etc

Module 4 and Project 4
The flexible HVDC transmission system. Transfer with HVDC, Tyristor-HVDC, IGBT-HVDC, UHVDC.

Intended learning outcomes

Having passed the course, the student should be able to:
• account for advantages and possibilities that the intelligent electric power grid can achieve both technically and commercially
• account for how distributed and fluctuating electricity production influences the design of the electric power distribution network
• account for which methods that can be used for supervision and diagnostics of electric power devices and how these methods can give increased reliability in the electricity supply
• analyse the consequences of different transmission methods for electric energy
• analyse which influence fast measurements and data collection have on the controlling properties of the intelligent electric power grid
• make qualitative and quantitative comparisons between different technologies based on conventional technology and power electronics
• be able to make models for calculation of the consequences for small-scale generation, energy storing as well as changed electricity consumption due to increased use of intelligent control, solar cells and heat pumps etc as well as electric vehicles that are loaded from the power grid but that can also intermittently deliver electricity back to the grid
• have a conception of which factors and aspects that control the design of the electric power grid.
