Project at a Glance: FOREWER is a collaborative publicprivate project funded by the French National Research Agency (ANR). The project started on October 1st, 2014 and will operate for 3.5 years.
Project ConsortiumProject Objectives  Develop reliable theoretical and numerical models and scenario generators for the wind resource distribution and power output at various spatial and temporal scales with a focus on medium to long term.
 Evaluate the potential of these tools for solving the forecasting and risk management problems relevant for the industrial partners of the project, such as the evaluation of the sensitivity of a proposed wind farm to climate variability and optimal placement of wind farms, determination of the required capacity of backup generators and optimal operation of these assets, and integration of renewable power sources into the grid.
 Apply state of the art statistical and probabilistic modeling tools (wavelets, stochastic processes) to the historical weather simulations in order to understand the multiscale behavior of the wind resource, analyze its variability modes and identify the predictable components of the distribution.
 Adapt the powerful statistical learning methods, developed by the statistics group at LPMA to identify the salient predicting features as well as the connections between renewable power production and the meteorological variables.
 Apply the statistical forecasting methodology to obtain seasonal and decadal projections of these relationships and produce reliable probabilistic forecasts of the renewable power production taking into account the climate nonstationarity.

Statistical learning for wind power: A modeling and stability study towards forecasting
0k  Sep 8, 2017, 1:34 AM by Lucie M (v1)
We focus on wind power modeling using machine learning techniques. We show on real data provided by the wind energy company Maïa Eolis that parametric models even following closely the physical equation relating wind production to wind speed are outperformed by intelligent learning algorithms. In particular, the CARTBagging algorithm gives very stable and promising results. Besides, as a step towards forecast, we quantify the impact of using deteriorated wind measures on the performances. We show also on this application that the default methodology to select a subset of predictors provided in the standard random forest package can be refined, especially when there exists among the predictors one variable, which has a major impact.

Modelling the Variability of the Wind Energy Resource on Monthly and Seasonal Timescales
0k  Sep 7, 2016, 7:28 AM by Peter Tankov (v1)
We study the variability of the wind energy resource in France on monthly to seasonal timescales. On such long‑term timescales, the variability of the surface wind speed is strongly influenced by the large‑scale situation of the atmosphere. We investigate the relationship between the large scale circulation and the surface wind speed, summarizing the former by a principal component analysis, so that the large‑scale mass distribution is described by a small set of coefficients. We then apply a multi polynomial relationship to model the monthly and seasonal distribution of surface wind speeds given the knowledge of these few coefficients. We finally apply this model to seasonal forecasts from the European Center for Medium‑range Weather Forecasts (ECMWF) in an attempt of forecasting the monthly and seasonal distribution of the surface wind speed. For one month time‑horizon, the forecasting performance is superior to climatology.

Optimal trading policies for wind energy producer
0k  Sep 7, 2016, 7:17 AM by Peter Tankov (v1)
We study the optimal trading policies for a wind energy producer
who aims to sell the future production in the open forward, spot,
intraday and adjustment markets, and who has access to imperfect
dynamically updated forecasts of the future production. We construct a
stochastic model for the forecast evolution and determine the optimal
trading policies which are updated dynamically as new forecast
information becomes available. Our results allow to quantify the
expected future gain of the wind producer and to determine the
economic value of the forecasts.

Article "Tails of Weakly Dependent Random Vectors" by P. Tankov, published in Journal of Multivariate Analysis (Volume 145, March 2016, Pages 73–86). This article presents methods for quantifying the tail behavior of random vectors which can be used, for example, to evaluate risks due to spatial dependency in wind power production.
