Course description of "Restructured Electricity Markets: Locational Marginal Pricing"
This course focuses on the "locational marginal
pricing" (or "nodal") model of "organized" or "centralized" dayahead and realtime electricity markets, which is in place in the Eastern
United States, the Midwest United States, California, the Southwest Power Pool, and Texas (the Electric Reliability Council of Texas, ERCOT). The course uses the ERCOT nodal market as its main example, but features of other North American markets, such as capacity markets, are also discussed. We will consider the solution of power flow, formulate
optimal dispatch as an optimization problem, consider offerbased economic dispatch, transmission and unit commitment
issues, and discuss pricing rules and incentives in markets, particularly in the context of transmission limits. The pedagogical approach is to first discuss pricing in organized electricity markets in the absence of transmission constraints and then introduce transmission constraints and their implications. We will also discuss
a number of other topics including energy and transmission price risk
hedging, network models, and capacity adequacy.
This course covers technical topics in power systems,
optimization, and economics at a graduate level and is presented in a mathematically rigorous fashion. A challenge in such a course is that few students will have background in all of these areas, and different students will have different backgrounds. Typical students should
have at least an undergraduate technical background in at least two of these areas and
expect to read outside of the class for any background material that they
have not studied prior to this class. The first half of the semester will rapidly review the background material for the class. The second half of the semester will then integrate this background material.
The slides for this course are available for downloading from www.ece.utexas.edu/~baldick/classes/394V/EE394V.html, and the links are highlighted below.
Downloadable video of the course materials are available from the CUSP website at the University of Minnesota.
Topics include:
 Recent history of electricity market restructuring in Texas:
 Regional entities,
 Texas and ERCOT,
 Regulatory jurisdiction,
 Milestones in Texas electricity restructuring,
 The locational marginal pricing market,
 Capacity adequacy concerns,
 based on Ross Baldick and Hui Niu, "Lessons Learned: The Texas Experience.'' In James Griffin and Steven Puller, Editors, Electricity Deregulation: Where to from
here? University of Chicago Press, 2005.
 Review of background material:
 There are three main areas of background material for this class: power systems, optimization, and economics, divided into six topics.
 The power systems material includes solution of nonlinear simultaneous equations and formulation and solution of power flow.
 The optimization material includes basic results in optimization theory and the formulation and solution of economic dispatch.
 The economics material includes microeconomics and economicdecision making in the electricity industry.
 You do not need to be familiar with all three areas at the start of the course. However, if you are not familiar with at least two of these areas then you may find that you struggle during the semester. You should also have familiarity with Matlab and Powerworld for use in the homework exercises.

 We will occasionally use the PowerWorld power flow and optimal power flow solver in class and in homeworks.
 You should Download and install the Educational version of the PowerWorld Simulator.
 A tutorial on how to use the solver is available at PowerWorld.
 The tutorial uses a 13 Bus System, and the tutorial demonstrates how to extract data from the system, as contained in 13 Bus Extracted Data.
 A PowerWorld implementation of the example system used in the Summary, with baseload and peaking generation, is available at 3 Bus System.

Expectations
Please come to office hours with
prepared questions.
I may have to cancel one or two
classes during the semester in order to attend conferences. We may need to
schedule makeup classes for these cancelled classes since the semester will be full of material to cover.
I do not take attendance and you are
free to attend or not attend class as you choose. However, if you come to
class, please be prompt. Please be seated in class by the
time the startofclass bell rings. If a homework is due, please put it on
the desk in the classroom prior to the start of class.
Textbook
The course will cover topics from a number of fields
including power systems, optimization theory, and economics.
Consequently, there is no single textbook for this class. However, the
slides are available online and I will plan to distribute copies of relevant
papers if necessary. Two useful references
for the power systems economics material is:
 Steven Stoft, Power System Economics: Designing
Markets for Electricity, IEEE Press and Wiley Interscience and John
Wiley and Sons, Inc., Piscataway, NJ, 2002.

Prerequisites:
The class will build on a background of undergraduate
economics, undergraduate electric power or circuit theory, and continuous and
mixedinteger optimization theory. I do not expect every student to have a strong
background in all three areas. However, if you do not have a background in
at least two of these areas, you may struggle in the class. I encourage
you to take the course as credit/no credit if you are concerned
about the background material. (If
you are looking for a nontechnical introduction to locational marginal pricing,
I also teach a oneday shortcourse that might suit you instead. See www.baldick.com
for details.)
For people from industry:
I strongly encourage people from industry to
attend. There are two basic options for attendance by
nonstudents:
 Auditing: Use this option if you do not need
credit for the course..
 Nondegree: Use this option if you want
credit for the course or your employer requires that you take the course for
credit. Apply through the Texas Common Application website, https://www.applytexas.org/adappc/commonapp.WBX,
for graduate admission to The University of Texas at Austin. You
should create a new admission application to The University of Texas at
Austin. Select "Graduate, U.S." admission or "Graduate,
International," as appropriate, and choose Fall 2006 admission.
Select admission to the "ECEEnergy Systems" major. Enter
the biographical information on "Page 1" and the other required
information on the successive pages. On "Page 2" be sure to
check the "Nondegree Graduate Student" box on question 13.
The application fee is $50 and the online application must be completed and
submitted. As well as submitting the online
application, you will need to submit transcripts of your degrees. Once
admitted, the tuition and fees will be between $1500 and $2000 for instate
residents and approximately $3500 to $4000 for outofstate.
