Abstract


In July 2015, a network of 65 virtually connected distributed energy storage systems (ESS) with

a total nominal power of 1 MW – so-called SWARM – was successfully prequalified for

frequency containment reserve (FCR) provision within the balancing area of TenneT TSO

GmbH in Germany. ESS were installed in private households possessing a rooftop photovoltaic

system. In contrast to ordinary ESS available in the market for home application, SWARM-

ESS do not only increase the households’ self-consumption, but they work as a virtual mass

storage. Coordinated by an automated control center, SWARM is able to provide FCR by

responding proportionally to frequency deviations of up to 200 mHz within few seconds and

thus, contributes to stabilizing the grid. Hence, SWARM represents a systematic decentralized

approach for meeting one of the main challenges of the energy transition in Germany.

Roll out and operation of SWARM are conducted by a cooperation between N-ERGIE

Aktiengesellschaft and Caterva GmbH. The project’s research activities are supported by

groups of the Friedrich-Alexander-University addressing both, economic and technical issues.

From an economic perspective, the identification of determinants of individual decision-making

in exposure to novel technology is emphasized. As far as technical issues are concerned, the

effects of distributed ESS on the grid, the provision of FCR by a virtual mass storage as well as

the operational behavior of SWARM are analyzed. To this end, a stochastic and hybrid simulation model is developed to generate time series of all power flows within each house as

well as the FCR provided. These time series are used for load flow calculations to identify the influence of ESS on the local distribution grid. All in all, this paper gives an overview of first experiences in the operation of SWARM as well as of research results from the different disciplines.
