Bayesian Inference for Estimating Generation Costs in Electricity Markets

Abstract
We model the relationship between generation costs and production schedules with a latent variable model, and estimate generation costs from observed schedules by Bayesian inference with balanced neural posterior estimation. On the IEEE RTS-96 test system, marginal costs are recovered with narrow credible intervals, while start-up costs remain largely unidentifiable from schedules alone.
