We consider two prominent mechanisms for the electricity market; the pay-as-bid mechanism, currently applied in certain control reserve markets, and the proposed Vickrey- Clarke-Groves mechanism, an established auction mechanism used in advertising and spectrum auctions, for example. Bringing in tools from game theory and auction theory, we compare the Nash equilibria of these two mechanisms in terms of social efficiency and strategic behavior of the players. Furthermore, by formulating a coalitional game corresponding to the electricity market, we propose alternative mechanisms that incentivize truthful bidding while ensuring shill bidding is not profitable. Finally, we analyze the proposed mechanisms in a case study based on electricity market data.

Game theory

Game theory is the study of mathematical models of strategic interactions among rational agents. It has applications in all fields of social science, as well as in logic, systems science and computer science. The concepts of game theory are used extensively in economics as well. The traditional methods of game theory addressed two-person zero-sum games, in which each participant's gains or losses are exactly balanced by the losses and gains of other participants.

Price mechanism

In economics, a price mechanism is the manner in which the profits of goods or services affects the supply and demand of goods and services, principally by the price elasticity of demand. A price mechanism affects both buyer and seller who negotiate prices. A price mechanism, part of a market system, comprises various ways to match up buyers and sellers. The price mechanism is an economic model where price plays a key role in directing the activities of producers, consumers, and resource suppliers.

Auction theory

Auction theory is an applied branch of economics which deals with how bidders act in auction markets and researches how the features of auction markets incentivise predictable outcomes. Auction theory is a tool used to inform the design of real-world auctions. Sellers use auction theory to raise higher revenues while allowing buyers to procure at a lower cost. The conference of the price between the buyer and seller is an economic equilibrium. Auction theorists design rules for auctions to address issues which can lead to market failure.
