In this paper, a deterministic security-constrained unit commitment (SCUC) model is deployed in order to optimize
generation output and allocation for spinning reserve considering different wind power dispatch modes. In this
model, the scheduling of power plants takes into account a simultaneous clearing of power, reserve capacity requirement
and CO2 emission and so on. Spinning reserve is modelled as an exogenous parameter which represents load uncertainty
and wind power uncertainty. Special attention in the study is given to determine the impact of different dispatch modes
with wind power and different levels of spinning reserve requirement on system operation and costs. The proposed model
can be formulated as a mixed-integer problem (MIP) and solved in GAMS by using the CPLEX optimizer. The model is
applied to a wind-fired intensive power system for three case studies. The results include the optimal spinning reserve and
generator output of each generator, CO2 emission cost and cost of wind power for each case study. The results show that
taking wind power as a control option can improves system operation and costs if wind generation and traditional sources
generation are coordinated properly.
