Abstract

This poster invites to a workshop on Extreme Power System Events in April 2025, and reports on a workshop for Minute Scale Forecasting from May 2024. Other current results are also reported on. Electric grid systems that want to operate with a high penetration of weather-driven renewable generation and other weather-related components need an interdisciplinary forecasting approach in order to optimize the system economics and reliability. Therefore, while anchored in IEA Wind, Task 51 activities to maximize forecasting performance and value assume a much wider scope, also encompassing PV, hydro, biomass, hydrogen, storage and other IEA Technology Collaboration Programmes (TCPs). The three existing Work Packages (WPs) on NWP Improvements (WP1), Power and Uncertainty Forecasting (WP2) and optimal use of Forecasting Solutions (WP3), are complemented by eleven work streams in a matrix structure. The three work packages span three distinct areas of challenge in forecasting for the weather driven energy system. The first area is the continuing effort to improve the representation of physical processes in weather forecast models through both new high performance initializations and tailored parameterizations. The second area is the heterogeneity of the forecasters and end users, the full understanding of the uncertainties throughout the modelling chain and the incorporation of novel data into power forecasting algorithms. A third area is representation, communication, and use of these uncertainties to industry in forms that readily support decision-making in plant and grid system operations and electricity markets. Task 51 focuses on facilitating communication and collaborations among international research groups engaged in the improvement of the accuracy and applicability of forecast models and their utility for the stakeholders in the wind industry, in the power sector and in the energy system.
