Abstract: A method and system for energy management in a power system. Target performance standards are calculated and used to measure performance and to comply with regulatory performance standards. The target performance standards are based on probability theory and are used to control power generation. The amount of corrective power necessary is based on the calculated target performance standards and the deviations of current performance values from the target standards.

Abstract: A system and method for generator startup cost modeling using a time counter are described herein. A method and system according to the invention may include assigning a binary value to one or more time segment variables each associated with an increment of the time counter wherein the sum of the one or more time segment variables is greater than or equal to a binary startup variable. The method and system may also assign a value to one or more startup cost variables associated with each of the one or more time segment variables. The system and method may then determine the startup cost of a shutdown time by summing the products of each time segment variable and associated startup cost variable. In another aspect the method and system may entail a sum of products of each binary time segment variable and time increment being less than or equal to a time-off variable.

Abstract: A method and apparatus for resolving energy imbalance in a real-time manner is disclosed. A plurality of market user interfaces are coupled to an imbalance engine which determines optimal dispatch requirements corresponding to supply and demand requirements of the market participants. The imbalance engine resolves in a real-time manner the dispatch requirements while considering the transmission limitations, ramping limitations, transmission facilities, and price data.

Abstract: The present invention is an apparatus for optimizing security constrained dispatch and pricing for the wholesale energy trading market. The imbalance market uniquely requires a real-time market for bidding and for providing the energy generation adjustments required to satisfy the imbalance.
