Research project SOLREV-2
Analysis and assessment of methods for determining solar resources and forecasts for the grid and market integration of solar energy
Our energy requirements are increasingly met by the use of solar technologies. For the design of a resilient energy system based on renewable energies, it is therefore becoming increasingly important to effectively integrate these fluctuating sources into electricity grids and energy markets. To enable this, solar power forecasts are fundamental for diverse energy management options such as the provision of control energy or optimised electricity trading processes. Furthermore, large-scale solar technology projects require reliable long-term data on solar radiation to mitigate entrepreneurial risk and promote investment. Against this backdrop, the research project SOLREV-2 (funded by the Federal Ministry for Economic Affairs and Energy) aims to develop guidelines and standards for model development and data use.

The research project SOLREV-2 focuses on evaluating and optimising existing models for the provision of solar radiation data and forecasts. The project participants aim to provide solutions for the grid integration of high shares of solar energy and thus contribute to the long-term yield security of solar power plants. The interest lies in innovative photovoltaic technologies such as bifacial power plants, floating PV and agrivoltaics, the implementation of which requires differentiated meteorological data. During the course of the project, instructions, recommendations and new standards will be developed, which in turn will serve as a basis for further model developments.
In this context, the Institute of Networked Energy Systems is working within the SOLREV-2 project to further improve the grid integration of high shares of solar energy and the yield security of solar power plants. To this end, the researchers provide radiation data and forecasts of solar radiation for the next few hours and develop new methods for solar radiation and solar power forecasting, which for the first time include measurements from the new MTG (Meteosat Third Generation) satellites. Against the background of increasing shares of solar energy in future electricity grids, the institute is also dedicated to the further development of energy resource analysis. To this end, the project team evaluates various climate models with regard to their forecasted solar radiation and highlights future developments with regard to typical climatic conditions, and the increase in extreme weather events.
