Reducing uplift payments has been a challenging problem for most wholesale markets in US. The main difficulty comes from the unit commitment discrete decision makings. Recently convex hull pricing has been shown promising to reduce the uplift payments. Meanwhile, however, the computation could be heavy to decide the convex hull price. This disclosure shows how to utilize a derived integral formulation of the single-generator unit commitment problem to facilitate the calculation of the optimal convex hull price by solving a linear program.
