Abstract
An operation control system for a wind farm having wind turbines includes: a remaining-lifetime estimation unit for estimating remaining lifetime of a component of each wind turbine; a sales-income estimation unit for estimating, for each wind turbine, an income from sales of electric power under a plurality of output control conditions; a maintenance-cost estimation unit for estimating, for each wind turbine, maintenance cost based on the remaining lifetime of the component under each of the plurality of power limit conditions; a power-limit-condition selection unit for selecting, for each wind turbine, a power limit condition that maximizes income obtained from the wind farm, based on the income from sales of electric power and the maintenance cost estimated for each wind turbine under each of the power limit conditions; and an operation command unit for sending an operation command to each wind turbine based on the selected power limit condition.
