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.
