Abstract: |
This letter proposes a novel hybrid component
and configuration model for combined-cycle gas turbines
(CCGTs) participating in independent system operator
(ISO) markets. The proposed model overcomes the inaccuracy
issues in the current configuration-based model
while retaining its simple and flexible bidding framework
of configuration-based models. The physical limitations—
such as minimum online/offline time and ramping rates—
are modeled for each component separately, and the cost is
calculated with the bidding curves from the configuration
modes. This hybrid mode can represent the current dominant
bidding model in the unit commitment problem of
ISOs while treating the individual components in CCGTs
accurately. The commitment status of the individual components
is mapped to the unique configuration mode of the
CCGTs. The transitions from one configuration mode to
another are also modeled. No additional binary variables
are added, and numerical case studies demonstrate the
effectiveness of this model for CCGT units in the unit
commitment problem. |
