Embodiments provide systems and methods for operating a power system to deliver energy. Embodiments include obtaining initial resource schedules for network analysis using a set of input and data validation functions; performing a network analysis with a full AC power flow in the energy system; executing a security constraint unit commitment function using transmission constraints output from the network analysis; determining an optimized outage schedule using the output of the security constraint unit commitment function; distributing the optimized outage schedule to a generation control and load management system; and directing operation of generator resources and managing loads to deliver energy to customers based on the optimized outage schedule. Numerous other aspects are provided.
