Abstract

Wind generation is the leading alternative for environmentally responsible power generation and for energy independence in the future. However, wind power output cannot be controlled same as conventional generation, and wind is not necessarily available to serve peak load. In this chapter, the use of a Sodium Sulfur battery directly coupled with a wind farm to provide generation shifting for serving peak demand and for limiting the wind farm power output ramp-rate is discussed. Results from field operation of a 1 MW, 7.2 MWh ...
