AbstractToday, mass presence of distributed energy resources (DERs) connected to the grid is often seen as having adverse effects on grid reliability and robustness. The apprehension is that it complicates or even compromises network management by distribution system operators (DSOs).The central aim of the Open System for Energy Services (OS4ES) project is to provide a solution that closes the current information, communication and cooperation gap between DERs and energy market actors. To this end, the OS4ES project delivers an innovative Open Service System that enables dynamic cooperation between these two parties. A Distributed Registry for DERs offers to involved actors the opportunity to reserve the aggregated flexibility of DERs as a grid management service in order to improve Smart Grid robustness and reliability. OS4ES will be based on standardized and interoperable communication interfaces, as well as generic interfaces among components producing, consuming or storing electrical energy.The OS4ES Open Service System includes laboratory and field tests under different service scenarios such as congestion management, energy trading, imbalance risk reduction and Volt/VAR optimization. An OS4ES User Group has been established to allow interested parties to gain a broader insight in the project and to actively contribute to the work packages of interest. Besides, standardization proposals will be prepared and submitted to the respective standardization committees.
