Power System Impacts of Wind Power

This chapter focuses on the wind integration studies - what is studied and how the studies are made. The chapter is subdivided into sections covering the main set-up for the studies, methodologies and results. A look on recommended practices and future work is made. Wind integration studies look at and how the variability and uncertainty of wind power will impact the reserves that power systems carry as well as scheduling and efficiency of other power plants. Impacts on the transmission grid adequacy and power adequacy (capacity value of wind power) can also be assessed. Often only wind integration costs are assessed, while the benefits of wind power, mainly through reducing the fossil fuel consumption and emissions in power systems can also be estimated. The main set-up of the studies will have a crucial impact on the results. In future trends like, use of demand side management will impact the wind integration study results.
