A one-sided flow based combinatorial auction electricity market model

摘要

A new market model based on combinatorial auction for electricity trade is introduced, where the central authority (CA) conducting the auction is integrated with the transmission system operator (TSO). The TSO receives the consumer demands and prices, and conducts a flow based combinatorial auction for the generators. For every subset of declared demands, a generator evaluates its potential production cost and bids according to this value. During the auction the transmission limits of the underlying power network are taken explicitly into account, thus the transmission capabilities are utilized efficiently. The model enhances most efficient utilization of the concave production characteristics of the generators. We show that in this concept the TSO is motivated for network expansion.
