摘要
This study evaluates market impacts of excess capacity across various wind and solar system penetrations. First, different fleet compositions are simulated in a production cost model to yield price outputs. Price statistics reveal a strong relationship between scarcity price events, resource adequacy, and the mean and standard deviation of prices. Next, a method is presented for adjusting resource adequacy to a chosen level, which links a capacity expansion model with a probabilistic resource adequacy model. © 2019 Elsevier Inc.
