| This work is motivated by the recent changes in regulatory policies towards inter utility-power interchange practices. If competition replaces regulation as the norm of electric power generation and bulk power supply, a number of changes would be required. The NOPR proposes unbundling the utility companies into: Genco (generation company), Transco (transmission company), and disco (distribution company). A central coordinating body is called RTG in FERC's 1993 NOPR.; This work has developed the foundation for market-based pricing of ancillary services in electric power transaction. It is used to design an auction market simulator.; The developed brokerage model provides a unified framework for merchandising and technical functions. This provides better coordination among the market participants as opposed to two-tier models.; Reserve margins and transmission losses are included to design an efficient pricing mechanism for providing correct incentives to achieve a reliable electric market place. The proposed mathematical framework is close to traditional optimal power flow problem. The developed formulation can be adapted for linear programming. The formulation has angular block structure which can be exploited to apply efficient decomposition techniques to solve a large scale power system problem.; The foundation is used to develop an automatic generation control (AGC) simulator and an electric power auction market simulator for a price-based system operation. The proposed scheme greatly improves control signals to unit dispatch and controllers. It includes ACE as a part of control error signal.; In the new environment. the plant operators are required to submit the price-based bids to perform electric power transaction. This is quite different from what the system operators are accustomed in a vertically integrated industry. The proposed simulator can be used as a tool to train operators how to bid.; The tool described should enable the analysis of proposed rules for the new environment. Issues, such as pricing of transmission losses, priority of transactions, emergency power, etc. can be studied. (Abstract shortened by UMI.)... |
