    Abstract

    In this paper, a novel concept for the description of energy storage in power systems with dispatchable and non-dispatchable generators and loads is presented. It is based on a system-perspective consideration of energy storage, generation and consumption. This means that grid-relevant aspects such as power rating, ramprate constraints, eciencies, and storage capacity are modeled, while the individual physical properties of the interconnected units are not taken into account. This allows the modeling of a physically very diverse unit portfolio with a single approach. The concept can be used for designing operation strategies for power systems based on ubiquitous energy storage, for example to buer non-dispatchable generation, as well as for the evaluation of the operational performance in terms of energy eciency, reliability and cost. After introducing the modeling approach and a categorization of unit types, a small simulation example is presented for illustration.
