Implementation of a Newton-based Optimal Power Flow into a Power System Simulation Environment by James

In this thesis, a Newton-based optimal power flow (OPF) is developed for implementation into a power system simulation environment. The OPF performs all system control while maintaining system security. System controls include generator megawatt outputs, transformer taps, and transformer phase shifts, while maintenance of system security ensures that no power system component's limits are violated. Special attention is paid to the heuristics important to creating an OPF which achieves solution in a rapid manner. Finally, sample applications of the OPF are discussed. These include transmission line overload removal, transmission system control, available transfer capability calculation (ATC), real and reactive power pricing, transmission component valuation, and transmission system marginal pricing. iv ACKNOWLEDGEMENTS I would like to thank Professor Thomas Overbye for his knowledge, guidance and support throughout my graduate studies. I would also like to thank the University of Illinois Power Affiliates Program and the University of Illinois Graduate College for their generous financial support. I would also like to thank my professors and friends from my undergraduate studies while at the University of Wisconsin-Platteville. The preparation and experience I gained there were invaluable. Special thanks go to Dr. Mesut Muslu and Dr. Richard Shultz. Finally, I would like to thank my family. My brothers Brian and Scott continue to be there for support and friendship. Most of all I thank my mother and father, Jan and Gene. They continue to supply the unconditional love and support which allow me and my brothers to achieve what we have and will.
