Flexibility is necessary to control the energy use to match the actual energy generation from various energy sources such as solar and wind power. However, before this project there was a lack of comprehensive knowledge… https://www.irec.cat/wp-content/uploads/2026/02/Logos-IREC_vertical-color_web.png600326
