Guidelines for renewable energy based supply system for various types of buildings

The autonomous supply of buildings with renewable energies is a great challenge. The main topic is the link between the demand- und the supply side at any time. Renewable generated electricity is subjected to the natural fluctuation. On the other hand there is the bad predictability of the user. To ensure a secure supply, the use of energy storage systems is required. In this paper, a guideline is developed to design an autonomous hybrid system based on renewable energies and an energy storage system for buildings. The guideline is applicable for every type of building and considers the user load. the location with its solar- and wind conditions, as well as economic aspects.
