Representing the Effects of Oligopolistic Competition on Risk-Neutral Prices in Power Markets

Abstract

Forward transactions are becoming increasingly important in most of electricity markets. In this view, this paper develops a methodology able to capture the complexities of power markets and incorporate them into the framework of risk-neutral probabilities. This is done by the statement of a model that split up the power price dynamics into two different components: on the one hand, a component aimed at representing costs and market power, which will be based on a static, non-cooperative game; on the other, a component representing short-term deviations from the static model.

Keywords: power markets, pricing models, market power, long-term/short-term decomposition
