A Mathematical Framework for Unit Commitment and Operating Reserve Assessment in Electric Power Systems

A mathematical framework is presented in this paper for operating reserve assessment based on a hybrid deterministic/probabilistic approach. The approach known as system well-being embeds the conventional deterministic criteria into a probabilistic method. The proposed mathematical framework includes the computational requirements in both spinning and supplemental reserves. Interruptible load is also included in the framework as part of the operating reserve. The impact of ramp-rate limits on economic load dispatch is incorporated in the overall framework. The computational tools required to incorporate factors such as load forecast uncertainty and postponable outages are also presented.
