Project Title: Coordination of Transmission and Distribution data eXchanges for renewables integration in the European marketplace through Advanced, Scalable and Secure ICT Systems and Tools (TDX-ASSIST)
This project designed and developed novel Information and Communication Technology (ICT) tools and techniques to facilitate scalable and secure information systems and data exchange between Transmission System Operator (TSO) and Distribution System Operator (DSO). The three novel aspects of ICT tools and techniques were developed in the project as follows: scalability – ability to deal with new users and increasingly larger volumes of information and data; security – protection against external threats and attacks; and interoperability –information exchange and communications based on existing and emerging international smart grid ICT standards.
The TDX-ASSIST project addressed the further research and development needed to ensure that greater levels of TSO-DSO interoperability can be realized, and to also harmonise a wider range of standardisation activities.
The following key TDX-ASSIST project objectives and outputs were achieved:
A model driven methodology to define and support TSO-DSO Business and System Use Cases was developed. All interoperability layers of the Smart Grid Architecture Model were addressed, using IEC standards
and associated tools. A repository including Use Cases, Common Information Model (CIM) and associated profiles was developed.
Use Cases relating to DSO to markets secondary ICT systems were developed. In addition to documenting the State-of-the-Art, needed services are defined and catalogued with their corresponding payloads.
Furthermore, the overall TDX-ASSIST architecture is defined and documented.
The design and development of TSO-DSO information and data access portals based on scalable, secure ICT infrastructure that can also give access to a wider range of stakeholders as appropriate to enhanced TSO-DSO interaction.
Use Cases, processes, methods and techniques as developed within the project were transformed into a series of evaluated TSO-DSO demonstrations, trials and field tests.
Assessment of the final project activity was used to quantify how scalability, security and interoperability combine to improve real power sector ICT processes. Targeted TRLs as specified in the project proposal were linked to quantitative improvements in the sector’s performance. In addition, a Use Case Management Repository has been developed and implemented as a key output of the project.
