Quasi-Stochastic Electricity Markets

Abstract

Summary of Contribution This article was inspired by price formation changes recently proposed and implemented in several U.S. wholesale electricity markets. The analysis draws from and contributes to three lines of literature. First, the paper specifies two mechanisms that lead to inefficient and inconsistent prices in real-world markets. Second, the article illustrates the importance of considering uncertainty in evaluating policies for pricing in nonconvex markets and observes that convex hull pricing, sometimes described as an ?ideal? due to its uplift-minimizing property in deterministic analyses, can perform poorly in settings with uncertainty. Lastly, the paper strengthens the theoretical basis for operating reserve demand curves by connecting their parameterization to outcomes expected in efficient stochastic markets.
