An advanced study of wind power variability on the Federal Columbia River Power System

With the ever-increasing demand for energy resources it has become essential for the development and integration of renewable energy resources to the existing grid. Among the various forms of renewable energy resources that have been utilized to meet load requirements, wind power and hydropower have been the most developed thus far. Wind power is non-dispatchable, making its integration with the grid challenging. It is therefore critical for other energy resources to compensate for the variation in generation. In the Pacific Northwest, hydropower comprises most of the reserves provided for generation. This paper discusses statistical methods used to establish relationships between wind power and possible sources of reserves, including hydropower, interchange power, and thermal power. The analysis done here attempts to study the impact of wind power on the other components of the power system.
