# Course description:

Today’s society heavily dependson electric power and we take for granted that it is available everywhere and any time. But have you ever wondered what it takes to enable this life style? The field of electric energy systems is currently in an exciting transition to the so-called “smart grid”. While this mainly means that we are increasing the communication capabilities in the system, it also includes the integration of renewable generation such as wind and solar generation,plug-in electric vehicles and the active participation of consumers. This course introducesthe fundamentals inelectric energy systems which will enable you to understand what it takes for you to have a reliable electric power supply at your house and what is currently discussed in the news about issues and challenges in electric power systems.

First, the general structure of an electric power system (current and future trends) will be introduced. This includes the following elements: electric power plants (renewable and non-renewable), transmission and distribution, consumers.\

Then, electric power is addressed froma mathematical point of view. The mathematical formulae for AC power and models for the above mentioned elements are derived. This allows determining how muchpower is flowing where. Furthermore, control concepts by which the balance between generation and load is guaranteed are discussed.

Learning objectives:

At the end of the semester, the student should be able

• to name the main components in an electric power systems

• to describe the structure and functionalities of these components

• to explain what active and reactive power is and what three phase power is

• to calculate the power flows in a power system if given the connections and

parameters of the main components

• to explain the dependencies between active / reactive power and frequency / voltage

• to name and explain control concepts applied in the electric power system

• to explain the basic concepts of the electricity market

• to calculate the flows when a fault occurs

• to show an increased alertness and understanding of articles to energy related topics

• to name and explain three major changes anticipated in the coming years

Outcomes:

(a) an ability to apply knowledge of mathematics, science, and engineering: The students

apply the mathematical tools taught in class to specific problem sets in the assignments.

(h) the broad education necessary to understand the impact ofengineering solutions in a

global, economic, environmental, and societal context: In the courseproject, the students

search for, read and analyze current newspaper articles acquiring an understanding for

existing challenges in the field of energy and the impact possible solutions may have.

(j) a knowledge of contemporary issues: By reading newspapers articles as part of the

course project, the students learn about contemporary issues in the field of energy.

(k) an ability to use the techniques, skills, and modern engineering tools necessary for

engineering practice: The techniques taught in class and practiced in the assignments, e.g.

power flow calculations, etc., provide the students with the engineering tools which they

will need in their professional life to solve engineering problems.
