The Energy Operation Model (EOM) is an open source production cost analysis tool that automatically performs hourly chronological simulations of unit commitment. EOM was developed at PNNL under RIAM and several other projects and has been validated for the Eastern Interconnection (EIC) against PROMOD IV, a widely utilized simulation software package for generation and transmission planning. EOM solves the unit commitment problem by minimizing total operational cost including fixed cost, variable generation cost, and startup and shutdown cost, subject to a set of unit and system constraints such as power output limits, minimum up and down time, ramp rate, power flow limits, power balance, and reserve requirements. The major outputs include various operational costs, generation by generator unit and category, fuel usage, and locational marginal price. Key enhancements to EOM developed under RIAM include the ability to simulate hourly temperature-driven generating deratings due to temperature or lack of adequate cooling water (Ke et al. 2015), a key capability that will underpin future analyses of grid stress under IM3 and other projects.
