In the last decade in Europe, the power generated by Renewable Energy Sources (RES) has significantly increased. For the electric power system, the integration of a high amount of power generated by RES represents a big challenge. Energy Storage Systems (ESS) may help to solve problems related to the grid integration of RES. In this study, an analysis of the benefits that a planned and dedicated Adiabatic Compressed Air Energy Storage (A‐CAES) system may provide to a distribution network with a high penetration of RES will be carried out. The A‐CAES system, taken into account in this investigation, is based on the proposed German study so‐called “ADELE project”. The technical benefits as well as the corresponding costs that A‐CAES brings to the system which were analyzed using the load and RES generation time series for 2010 and 2020, and were based on technical data from a selected part of a German distribution power network, were evaluated and results of those broad investigations are presented in this study. The result of the investigations shows that the direct technical benefits are quite limited for the A‐CAES technology as it exists today.

The power system, especially on the distribution level, is subject to different changes due to transition process to renewable energies. On the other hand customers receive more possibilities to operate actively with the local system. In this paper a concept of a future control center for the smart distribution energy systems is presented to meet these challenges. Starting with an overview of future tasks a proposed architecture of a future distribution system is shown. The new components that are need for distribution system automation are introduced and modeled in HTML in detail. An overview of future services like full observability is given and components that are incorporated into the power system are described. An execution of the data management of such complex systems requires standardized plug in protocols, i.e. IEC 61850 and IEC 61970. This most relevant aspect is prioritized also in this paper. Finally a structure of a smart control center for future distribu tion systems is given
