Market-based integration analysis of enabling technologies for large-scale wind energy conversion.

摘要

Generation based on the conversion of wind energy is now the fastest growing source of electric energy in the world. This mode of production offers environmental, strategic and economic benefits. Despite these benefits, integrating wind plants, which are characterized by stochastic output, remain a formidable obstacle. At present, utilizing the flexibility of the power output of non-wind plant generators in most systems is sufficient for integration. The scalability of this method to integrate large additions of wind plants to the system is questionable unless uneconomic expansions in non-wind plant generation are made. Consequently, alternative methods of integration are sought and will ultimately be adopted if proven to be technologically and economically viable. In this dissertation, a method for assessing the market-based viability of wind plant integration through the use of generation, forecasting, and energy storage technologies is developed. Innovations of this dissertation include the development of wind plant and energy storage models; an energy storage control scheme and scheduling strategies; and a market simulator. A 180-bus representation of the Western Electricity Coordinating Council network with 30% wind plant capacity penetration is developed and validated as a test bend system. Explicit market simulation indicates that the forecast technology has significant impact on wind plant integration costs and that energy storage is an important enabling technology for the future as fuel costs rise.
