Robust generation maintenance scheduling considering wind power and forced outages

Generation maintenance scheduling has system level and equipment level aspects. At the system level, large-scale integration of wind power brings about significant challenges for classical generator maintenance scheduling. At the equipment level, forced outages of power equipment caused by wear affect maintenance decisions. Here, the authors report a robust optimisation model for maintenance scheduling considering wind power integration and forced outages of equipment. An uncertainty set is used to describe fluctuations in the wind power, and a method to control the conservativeness of the robust model is developed. An outage model is used to describe the impact of the operating conditions on maintenance decisions. The effects and advantages of the model are demonstrated via numerical simulations.
