Weather intelligence for wind energy - WILL4WIND


The WILL4WIND Action, financed by EU (grant IPA2007/HR/16IPO/001-040507), aims at reducing the meteorological uncertainties of wind energy integration, thus reducing the cost of wind energy integration and providing support to the growth of the wind energy sector in Croatia. The Action is built on a multidisciplinary collaboration between research, technology, utilities and business/industry, as well as between wind energy and meteorology sectors.


The WILL4WIND Action is a response to the real needs of the three target groups: i) transmission system operators, ii) wind power plant operators and iii) wind energy consultants for policy makers. WILL4WIND tackles the Croatian national-level shortcoming related to wind energy integration – top performance wind and wind power forecasting integrated into wind energy management. Therefore, the Action deals with the entire life-cycle of forecast information: its production in a model chain of dynamical, statistical and machine learning probabilistic prediction technologies, its adaptation to the needs of the wind energy sector to its integration into wind energy management processes.

Main body of abstract

Up to date, Croatian wind energy sector lacks a top performance wind energy management, in large part due to the lack of state-of-the-art prediction technologies adapted to the challenging wind climate of Croatia. The region is prone to severe downslope bora windstorms characterized with hurricane force winds, high variability and frequent ramps as well as extreme turbulence. Therefore, specific objectives of the WILL4WIND Action are to:
• enhance the wind prediction capabilities to support the safe and efficient integration of wind power plants into electric power system;
• assess the performance improvement of the advanced wind prediction system and to predict the associated day-to-day forecast uncertainties;
• integrate the improved wind prediction technology into the forecasting and wind energy management processes by developing dedicated software;
• raise awareness on the weather-related research results and to identify the key joint R&D priorities for the benefit of the Croatian industry in the wind energy sector.

The WILL4WIND prediction system is composed of a dynamical component (numerical weather prediction models reaching 1 km grid spacing) and statistical probabilistic post-processing. The temporal scales covered with this approach are ranging from hours to days, while periods on range from minutes to hours (i.e. ultra-short-term forecast) are predicted using neural networks. The Action will unify the above components into a model chain and help integrate predictions into business processes of the wind energy sector through dedicated software. Therefore, the Action will affect regulation of the electric grid, balancing reserve and operation of the individual wind power plants.


Management of supply&demand in an electric grid is a complex process that may benefit from state-of-the-art prediction technologies adjusted to the purpose using two-way communication among the relevant parties: utilities, business/industry, research, wind energy and meteorology sectors. Through joint efforts of the relevant Croatian players in the wind integration business, the WILL4WIND Action aims to reduce costs of wind energy integration, to unlock the potentials of industry and SMEs and to boost overall Croatian competitiveness in the wind energy sector. Moreover, the Action aims to promote a productive environment for the commercialization of weather-related research results and innovations.

Learning objectives
-learn what type of projects is currently financed by EU
-showcase multidisciplinary nature of the wind energy integration issue
-provide Croatian experiences related to wind energy integration
-promote interoperability of research, technology, utilities and business/industry, as well as wind energy and meteorology sectors
