摘要:
This paper provides the modeling of dynamic ramping in unit commitment. Ramping up/down limits could be a constant, stepwise, or piecewise linear function of generation dispatch. The dynamic ramping limit is modeled as mixed integer linear constraints, add unit commitment is solved by a mixed integer programming (MIP) solver. Test results show the impact of dynamic ramping on unit commitment and the importance of modeling dynamic ramping in the minimization of system costs while taking into consideration physical and financial constraints of power systems.
