ECE Graduate Seminar
March 22 – WEB 1230 – 3:05 p.m.
“Microgrid-based Power System Expansion Planning”
Microgrids generate, distribute and regulate the flow of electricity to local customers, representing a modern small-scale power system with a high degree of flexibility and efficiency in both supply and demand sectors. The integration of microgrids in distribution systems will offer a decentralized control of local resources for satisfying the network reliability and the power quality required by local loads. The high investment cost of a microgrid, however, is a major drawback to its development.
In this talk, research experiences in microgrid-based power system expansion planning will be shared. The proposed mathematical model to incorporate microgrid investments to grid-based generation and transmission expansion planning will be presented. The objective of the expansion planning problem is to minimize the total system expansion cost comprising investment and operation costs of local microgrids, the
co-optimized planning of large generating units and transmission lines, and the expected cost of unserved energy. The proposed model is decomposed into a planning problem and annual reliability subproblems to enhance the computational efficiency, and the final solution is obtained using an iterative approach. Numerical simulations demonstrate the effectiveness of the proposed microgrid-based power system expansion planning and explore the economic and reliability merits of microgrid planning as compared to grid-based generation
and transmission upgrades.
“Integrating Electric Vehicles into the Power System through Vehicle-to-Grid”
March 25 – WEB 1230 – 3:00 p.m.
Dr. Eric Sortomme
Senior Power Systems Engineer
Alstom Grid – Seattle, Washington
As the number of electric vehicles (EVs) increases, so might the impacts on the power system performance, such as over loading, reduced efficiency, power quality, and voltage regulation particularly at the distribution level. Intelligent control of EVs charging with vehicle-to-grid (V2G), the provision of energy and ancillary services to the grid from an electric vehicle, is a possible solution to these problems. In this presentation V2G scheduling in energy markets is optimized to provide maximum benefits to the customers and the system. The algorithm accounts for distribution feeder constraints and customer driving profiles Simulations in the Texas energy market show that scheduling V2G services within a feeder constraints reduces line losses, and eliminates line overloads and voltage sags below ANSI standards. This is done while achieving significant economic benefits for customers and utilities.
Biography of Eric Sortomme

The public is invited
Plain Talk —
April 30 – May 2, 2013
There are also other sessions being offered throughout the US (see schedule below).
One of our missions at PES is to provide education within the marketplace to people that work with, or in, the Power Industry, but are not necessarily formally educated in this technical discipline.The “Plain Talk About the Electric Power System” series was created to meet this educational need. These courses provide insights into the concerns of engineers, the demands of regulators and consumer groups, and the factors and trends that impact the operation of today’s electric power systems. The courses are also beneficial for non-power engineers who are transitioning to the electric power industry.
I am writing to you today to invite you to share this course offering with any colleagues or business associates that you feel would benefit from this knowledge. For your convenience I have included an email draft below that you can forward. (See gift info in first paragraph!)
As you can see from the sampling of job titles that registered for the courses in 2012 the audience that is interested in gaining this knowledge is broad.
2012 Plain Talk About the Electric Power System” Course Attendees

“Application of Semidefinite Optimization Techniques to Problems in Electric Power Systems”
The increasing interconnectedness of electric power systems provides both opportunities in improving economics and challenges to maintaining reliability. Recent advances in semidefinite optimization techniques provide promising avenues for
addressing these opportunities and challenges. The ability to obtain a globally optimal solution to semidefinite optimization problems provides an advantage over existing techniques, which are only guaranteed to find local solutions. This seminar discusses two applications of semidefinite optimization techniques to topics in electric power systems. The first application contributes to power system economics with a semidefinite relaxation of the optimal power flow problem that is capable
of providing a globally optimal system dispatch. The second application contributes to power system reliability with a sufficient condition for power flow insolvability that yields a voltage stability margin to the power flow solvability boundary.
