This paper proposes a new simulation method that can fully assess the impacts of large-scale wind power on system operations from cost, reliability, and environmental perspectives. The method uses a time series of observed and predicted 15-min average wind speeds at foreseen onshore- and offshore-wind farm locations. A Unit Commitment and Economic Dispatch (UC-ED) tool is adapted to allow for frequent revisions of conventional generation unit schedules, using information on current wind energy…

TLDR
Simulation results clearly show that the STATCOM unit can smooth well the wind-generator output power & also maintain the terminal voltage at rated level, and it is reported that STATCOM can significantly decrease voltage fluctuations of grid connected fixed speed wind generators.
