Wind correlation analysis between Greenland and Europe

Abstract

This article is dedicated to the development of computational methods for processing time series from wind speed signals. These computational methods are designed under the light of electricity generation from this intermittent renewable source. We propose to define the notion of critical time windows for measuring the proportion of the time during which renewable energy fields may simultaneously not produce sufficiently, i.e., with a load factor lower than a predefined threshold. Using this type of criterion opens the door to expressing optimization problems describing how to choose the localizations where to install production capacities. The proposed methodology is benchmarked using wind time series data from Europe and Greenland. In this document, two sets of time series are considered: the first one was generated using the MERRA-2 from NASA, while the second one was generated using the MAR model, a regional model taking into account Katabatic winds. First experimental results illustrate the fact that connecting Western Europe with Greenland may effectively decrease the proportion of critical time windows.
