To improve reserve deliverability, independent system operators (ISOs) acquire reserve on a zonal basis to ensure the reserves are at least zonally distributed. Notwithstanding the ability for zonal approaches to improve the reserve location, such approaches are imprecise and do not guarantee reserve deliverability on a nodal basis. In order to satisfy operational requirements, unreliable market solutions...
In real time market operations, operators need to monitor available on-line capacity and evaluate whether online resources and upcoming commitment can meet both energy balance and reserve requirement in the near future. However, available online generation capacity may not always be deliverable due to transmission congestion. This paper proposed a deliverable generation capacity calculation formulation...
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...
Under Midwest ISO's real-time market, energy and ancillary service products are co-optimized. It is very important for operators to have an indication of where the system stands and take proper action if needed. In this paper, both analytic and numerical methods are presented to evaluate the available room to meet power balance and reserve requirements. It essentially presents indexes on how far away...
