With increased sensitivity of the deregulated electric power market to power trading vagaries and their potential influence on network security, reliability, and stability; regulation at the US grid level may be warranted. Chuck will outline newly developed technologies in electric power transmission, distribution networks, and database technology, enabling near real time solutions for very large loosely coupled network power networks. Real time data from substations operating at 230 Kvolt and higher and all branch flows from those stations can be assembled on one large data server and made available to authorized personnel. Calculations can be carried out in near real time and can be used to avert a potential nationwide blackout, voltage sag, or frequency deviations that would cause catastrophic financial hardships on the country. The approach includes real time detection of anomalies, as well as near real time comparison of the current performance of the overall system to the optimal behavior, i.e. a direct comparison of the current generation dispatch with the optimum economic power dispatch. A distance measure is proposed to provide real time indication of the overall performance of the deregulated power grid. Recommended control actions are computed using recently developed algorithms for automatic clusterization, and subsequent calculation of control actions necessary to avert collapse.
Charles H. Wells provides technical sales support in the power and process industry. With over 30 years experience in real-time control and monitoring, Dr. Wells published over 50 technical papers, awarded three US Patents, and co-authored two textbooks. While at EPRI, Dr. Wells was responsible for developing the Institute’s software quality guidelines as well as software commercialization. He introduced an automated software quality metric used by all software developers. Quality metrics were used on all released software including some of the large legacy software programs like PSAPAC.
Dr. Wells, received his BS in Chemical Engineering at Vanderbilt University; and a MS in Chemical Engineering majoring in Polymer science and PhD in Electrical Engineering under Prof. John Zaborszky at Washington University specializing in modern control theory. He is a registered Professional Engineer in Chemical Engineering and Control Systems.
