Facilitating DER energy services for grid management via OS4ES: Aggregated flexibility, class model and matching algorithms

The European electricity infrastructure is challenged by the deployment of large numbers of DER systems in the grid. The massive deployment complicates the network management done by System Operators: DSOs, TSOs and BRPs. To cope with these adverse effects, the use of smart strategies using the flexibility potential of DER systems has been advocated. The Open System for Energy Services (OS4ES) framework, with a distributed registry for DER Systems is designed to exploit flexibility and to close the current gaps of information, communication and cooperation between DERs, DSOs and BRPs. This enables a new process for identifying, aggregating and creating value out of flexibility. In this paper relevant parts for emerging the OS4ES process are outlined. One part presents the OS4ES defined energy services for flexibility involving DERs. Based on this and on the information that needs to be exchanged between DERs and other parts of the system in order for such services to be executed, will introduce the vital and interesting elements of the semantic class model of DERs. OS4ES is strongly based on standardized and interoperable communication interfaces, as well as generic interfaces among components producing, consuming or storing electrical energy. Also the general context and the scope of the matching algorithms that are needed to support OS4ES registry-related functionalities will be sketched, presenting the DER system services searching functionalities to be dealt with.
