The uncertainty and variability associated with stochastic resources coupled with the constantly changing system operating conditions introduce new challenges to power systems. Smart, well-designed reserve policies are needed to assist the operators in maintaining system reliability. This paper presents a reserve response set model, which improves upon existing deterministic models. The proposed model aims to address the allocation and deliverability issues associated with reserves by using reserve response set policies and by modeling the predicted post-contingency effects of nodal reserve deployment on critical transmission elements. The performance of the proposed reserve model is compared against contemporary deterministic programs and an extensive-form stochastic program. The results show that the proposed reserve model outperforms the contemporary models and improves the deliverability of reserves post-contingency at reduced costs. All numerical results are based on the IEEE 118-bus and the 2383-bus Polish test systems.
