The Research on a New Bidding and Auction Approach in the Market for Ancillary Services and Its Application

摘要

After the electric power industry industrialization, bidding and auction are the principal function in the market for ancillary services. In these years, a few countries which take the fast step in the electric power industry such as American (in California) and England, their bidding and auction approach is: the operation managing operation in electric power industry (such as ISO in California of America), take the bids according to the ranking from the highest quality ancillary services to the lowest. The market-clearing price (MCP) is the highest price among the accepted bids at that the ancillary services requirement is met, and MCP is also called as the ancillary services payment. This method is called as the sequential approach; however, the sequential approach could not be necessarily to minimize the total payment for the ancillary services. This paper presents a new approach for ancillary services. The new method make the demand for a lower quality service can be substituted by a higher quality service, so the lowest payment for the ancillary service could be gained through carry out the optimal searching, and the total demand for all markets is not changed. This paper discusses the feasibility and effect of the new method; furthermore, an example is presented to illustrate further the new method.
