Development of multi-objective solutions and an electronic commerce software architecture for commodity trading in deregulated power markets

Power industry is presently undergoing a radical restructuring globally. Vertically integrated utilities are being broken up into competitive entities, which seeks to introduce competition into the electric power markets in order to improve the economic efficiency. In a deregulated power market, buyers and sellers determine the price of electricity through negotiation. Because of these changes, the concepts and principles of power market are under extensive study and the price of electricity has become the focus of power system operation.; Conflicts exist everywhere in the deregulated power industry. For example, in the energy markets, sellers and buyers are competitive market participants who have their own objectives. Sellers seek to maximize their profit, and buyers try to buy the cheapest electricity. Thus the market participants' objectives are conflicting. Another example is in those power markets where auctions are carried out to procure various commodities such as energy, and ancillary services. Each auction has its own objective and operation rules, which may interact with those of other auctions.; This research intends to provide multi-objective solutions for deregulated power markets with conflicting objectives. In this dissertation, the following problems are studied: (1) Dispatch problems in deregulated energy markets; (2) Coordinating auctions problem in deregulated power markets.; In the ongoing process of the restructuring of power industry, the Internet and Information Technologies (IIT) have been transforming our world in a more profound way. One example is that IIT is changing traditional business and economic paradigms with Electronic Commerce being viewed as the inevitable choice. Presently, power markets are at the design and implementation phase where the concepts and technologies of Electronic Commerce can bring about a new revolution in the deregulated power industry.; This research also develops an Electronic Commerce software architecture for the deregulated power markets. The following methodologies are studied to fully unleash the power of IIT: (1) Introduce component technology into the design of power market; (2) Introduce software architectural style into the design of power market supporting software system; (3) Introduce wrapping techniques to integrate the existing Energy Management System into power market supporting software system.
