We present our ICT-based approach of an integrative energy management in the distribution grid aiming at a substitution of fossil generation capacities. Using the example of a strong wind power gradient, the potential of the following concepts to adapt to extreme load curves within short time is shown: a. Reactive scheduling of small-scale generation units b. Virtual Appliances for load shifting c. Load management of battery systems e.g. in Plug-in Electric Vehicles d. Dynamic product build-up in Virtual Power Plants The proposed elements of an integrative energy management work on different time scales: The scheduling of residential combined heat and power plants can lead to feed-in shifts of several hours, whereas load shifting with domestic appliances like refrigerators imply load shifting of less than an hour for a single device. These concepts have to be integrated to adapt local grid load curves to wind power feed-in characteristics.
