This paper presents an approach based on dynamic optimal power flow (DOPF) to clear both energy and spinning reserve day-ahead markets. A competitive environment is assumed, where agents can offer active power for both demand supply and ancillary services. The DOPF jointly determines the optimal solutions for both energy dispatch and reserve allocation. An attractive feature of the proposed approach is that the final optimal solution will automatically meet physical constraints such as transmission and generating limits and ramp rate restrictions. In addition, the proposed framework allows the definition of multiple zones in the power network in order to enforce reserve allocation rules.
