EH2745 Computer Applications in Power Systems

2

Overview

The purpose of Assignment I is to let you combine the software techniques we have studied

during the first part of the course, and using these create an embryo of Energy Management

System. The assignment combines Java programming, CIM-XML modelling and parsing,

relational databases development and finally a minor part in power system analysis.

To solve the assignment you should work in groups of 2, although it is perfectly OK to work on

your own.

Assignment

The assignment involves developing a Java application that fulfills at least the following

requirements:

1. Can take the CIM-XML files (EQ & SSH) of the 5-bus system as input and parse

required information about the power system. CIM classes and attributes required to

parse are provided in Table 1. All equipment attributes are available in the EQ file except

the operational parameters which are contained in the SSH file. Parse both files and

collect the required information from the respective profiles.

2. Create an “in-memory” data structure containing the data in the CIM-XML Files

3. Develop an algorithm for topology analysis to convert the bus-breaker model into a busbranch

model.

4. Determine the admittance (Y) matrix of the five-bus system and present it as output.

The assignment is graded as Pass by a group that submits a Java program (in accordance with the

requirements below) that fulfills the above requirements.

To Pass with distinction and gain bonus points for the exam, the quality of the solution should

exceed those requirements. Examples of factors that determine the quality of the solution are:

Using a database for storing data during processing

Adherence to good programming style

Flexibility of the program to allow other input data e.g. parse edited CIM files and

determine the Y matrix from those.

Presentation of results, and interaction with the program in a GUI

Further analysis of data, beyond the Y matrix determination.

Submission of solutions

The source code and screencast in which you present your solution shall be uploaded to the

course page no later than May 13th 2019 at 21:00. In the screencast, both group members must

present approximately 50% of the work. The screencast videos should not exceed 15 minutes and

should contain commentary and explanation of the functions and classes in the code and its

overall structure rather than going though it line by line.

References and plagiarism

Please note that when solving the assignments co-operation between students is allowed and

even encouraged. However, the project groups are responsible for the content of their own

program and plagiarism will result in an immediate failing of the assignment in addition to a

written report to KTH’s central disciplinary committee. This means that all groups should write

their own programs. You are not allowed to use source code from other groups and you are not

allowed to copy source code from the internet.
