EI2455 Smart Electrical Networks and Systems 7.5 credits

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.

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.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Further information about the course can be found on the Course web at the link below. Information on the Course web will later be moved to this site.

Students who have not completed earlier course occasion are assessed by carrying out the home assignments and projects that applied when they read the course.

In this course, the EECS code of honor applies, see:
