Up with wind

In this article, we focus on three important aspects of large regional wind-integration studies: wind data development, transmission analysis, and the modeling of wind-integration scenarios. Careful development and validation of the wind data inputs to an integration study are essential to obtain meaningful results. New transmission will be required for much of the future wind development; hence, it is imperative to plan for this transmission because it takes longer to build new transmission than it does to build wind plants. The transmission analysis can include a transmission-expansion plan to be done as part of the wind-integration study or can use existing transmission plans and analyze potential congestion. Finally, scenario modeling investigates the operational impacts of wind variability and uncertainty. The production cost models can be either deterministic or stochastic in nature. They can examine a wide range of sensitivities.including unit commitment and operating reserve considerations, different market scenarios, carbon reductions for different scenarios, storage considerations, forecasting, and the contribution of wind to system reliability.
