In this project, a smart and green energy management system will be demonstrated at Warmtenet Ede. This system means that the control of different sustainable heat sources is merged into one system. In this way, it is possible to respond to peaks and valleys in the production of, for example, solar and wind energy. From the operating system, overarching data (metadata) is directly entered into a Digital Twin. This is a digital simulation model of the heat network that determines the most optimal use of different heat sources. This makes the heat network more efficient and less heat is lost. Through a connection to the electricity grid and a trading platform, optimal renewable energy can also be added and sold on the electricity grid.
