TY - JOUR A1 - Selleneit, Volker A1 - Mast, Tanja A1 - Holzhammer, Uwe T1 - Method to describe and rate the ability to provide flexibility of residual power providers in electricity grids with a high share of variable renewable energies JF - CIRED - Open Access Proceedings Journal N2 - With an increasing ratio of variable renewable energies in Germany, power supply has to be ensured by providing flexibility from controllable supply and demand energy conversion units. For residual electricity supply, utilities in the industrial sector or flexible biogas plants may be suitable flexibility options. To describe and rate different technologies or utilities in terms of their ability to provide flexibility, a definition of flexibility and an innovative method to describe flexibility considering the grid requirements is elaborated. The method is based on a solid definition of flexibility indicators suitable for all technologies. For an increased flexibility, in many cases, it is reasonable to add supporting technologies like a storage to a utility or biogas combined heat and power (CHP). Such utility configurations can also be described with the elaborated method. The method can also make a valuable contribution to all distribution systems or utility system modellers as it can be taken as a basis for the modelling. In this study, the definition of flexibility indicators is described in detail and used on the example of a biogas CHP plant.
