Course description and aims

This course focuses on operation and control technologies of an electric power system, on which modern society heavily depends, putting due emphasis on system technologies. Topics include control of active and reactive power, modeling of power apparatus, surge phenomena in a power system and analysis techniques for load flow and stability.

Student learning outcomes

At the end of this course, students will be able to:
1) Understand basics on operation and control of an electric power system;
2) Understand various phenomena observed in an electric power system under normal and fault conditions;
3) Understand fundamental methods such as load flow and stability analyses for a power system.


frequency control, voltage control, economic load dispatch, load flow analysis, angle stability, cascaded outages, stabilizing control, overvoltage, surge, DC transmission.

Competencies that will be developed

Intercultural skills Communication skills Specialist skills Critical thinking skills Practical and/or problem-solving skills

Class flow

1) Lectures are given based on the materials distributed through OCW-i. Students are required to make preparation and review with the materials.
2) Students must submit a report on exercise problems assigned in each class.
3) Solutions to the problems assigned in the previous class are explained at the beginning of each class.
