Accelerating Computation of the Unit Commitment Problem (Presentation): NREL (National Renewable Energy Laboratory)

Abstract

Production cost models (PCMs) simulate power system operation at hourly (or higher) resolution. While computation times often extend into multiple days, the sequential nature of PCM's makes parallelism difficult. We exploit the persistence of unit commitment decisions to select partition boundaries for simulation horizon decomposition and parallel computation. Partitioned simulations arebenchmarked against sequential solutions for optimality and computation time.
