Incorporating post zonal reserve deployment transmission constraints into energy and ancillary service co-optimization

Summary form only given. This paper presents a new approach implemented in MISO day-ahead and real-time Energy and Ancillary Service Market clearing processes to address the reserve deliverability issue. In this approach, MISO enhanced the co-optimization process to incorporate post zonal reserve deployment transmission constraints. Reserves are procured within the co-optimization to meet both market-wide reserve requirements and ensure their deliverability on a zonal basis. As a result, zonal Market Clearing Prices (MCPs) for reserves can properly reflect the effects of zonal reserve deployment on transmission constraints under consideration.
