This course is an introductory subject in the fields of power grid control and operation, particularly focusing on electric energy generation and transmission/distribution. Electrical power systems and machines are the foundation of the modern economy. Electric power has become increasingly important as a way of transmitting and transforming energy in residential, commercial, industrial, military, and transportation uses. Numerous systems and machines have been, and will continue to be, developed for the conversion, delivery, and use of energy in electrical form. The growth of solar energy, wind energy, and other resources, combined with new trends such as electric and hybrid vehicles, also has a profound impact on global society. For undergraduate- and graduate-level students, this course emphasizes general aspects of electrical energy generation and distribution, microgrid infrastructure, renewable resources (e.g., wind and solar), and efficient load devices (e.g., electric vehicles and HVAC systems) in smart building. The class activity ranges from operation of large utility systems and microgrids to control of energy devices using microsensors (e.g., phasor measurement units). This course will be useful to students who pursue careers or research in electric power systems, smart grids, power electronics, and development or use of electric motors and generators.

The prerequisites for this course are EECE 231 (회로이론)or permission of the instructor.

Please consult with the instructor if there are any questions about preparation.

Each student will complete 8~10 problem sets, 1 quizzes, and 1 final-term exam.
Graduate students are allowed to take this course, although it is intended primarily for undergraduates. Each graduate student will have additional problems on the problem sets. These problems can be expected to require more initiative, in-depth analysis and will generally be harder than the problems expected for undergraduates.
Each graduate student or each pair of graduate students will be asked to formulate and carry out a project in an area related to the subject. Possible project examples are on distributed generation, optimal control of voltage regulating devices (e.g., on-load tap changers and shunt capacitors), demand response of electric vehicles and HVAC systems, and integration of onsite renewable generators to rebuild rural electric power grids. This project will be launched, fairly early in the term, after a meeting with the instructor.

In the grading schemes below, the percentages are approximate and meant as a guideline. The percentages will be confirmed based on the performance of students after the 1st quiz.

Grading criteria for undergraduates: 8~10 Problem sets (50%), 1 Quizzes (20%), 1 Final-term exam (30%)
Grading criteria for graduates: 8~10 Problem sets (50%), 1 Quizzes (20%), 1 Final-term exam (30%)

The course material will include
 fundamental of electric network theory (i.e., generation and distribution and active and reactive power);
 analysis of poly-phase transmission lines with respect to inductance, capacitance, balanced and unbalanced lines;
 simplification of problems using per-unit and transformation techniques;
 interconnection of electric power apparatus and operation of power systems;
 simplification of power flow calculation and discussion on various optimal power flow calculation methods;
 analysis of transmission line faults (e.g., fault current and voltage) using positive/negative/zero sequence components;

The instructors will provide hardcopies of lecture notes on schedule, if needed. There are additional references strongly recommended and possibly available online.

“Homework Policy”
We expect that accomplishing the homework on one’s own is the best way to acquire good scores from the quizzes and final-term exam. Therefore, we will impose NO penalty on the homework submitted before issuing the solution. However, we strongly encourage students to complete the homework on schedule to keep up with the lectures. The instructor will ask individual meetings with the students who do not submit the homework two times in a row.
We do not object to collaboration on the homework, but still expect each student to turn in only his or her work. Please do not copy others’ homework solutions, and any question will be welcome during the office hours. Discovery of such copying is likely to result in high penalties.
There may be no collaboration on the quizzes and final exam; we will inform you about the use of outside aides such as ‘crib sheets’ for each quiz.

After the course, the instructor will help students submit one domestic or international conference paper based on their term projects.
