2. Motivation • Network operators should facilitate consumer access to all markets while maintaining the highest level of supply security. • Trends of consumers becoming active market participants necessitated a revision of interaction between Transmission System Operators (TSOs) and Distribution System Operators (DSOs). • The operational and planning arrangements between TSOs and DSOs are to be revised and developed to support market framework that unlocks potential of consumers. • Requirement for efficient exchange of information and data, with more frequent update with less human effort.

3. Overviews • The three year project, started on 1st October 2017 • Aims: • Develop new Information and Communication Technology (ICT) tools and techniques that facilitate scalable and secure information system and data exchange between TSOs and DSOs. • Enhanced TSO-DSO interoperability, considering DSO interaction with other market participants (such as DSOs, Aggregators, DER operators). • Final project activity will be used to quantify how scalability, security and interoperability combine to improve real power sector ICT processes.

4. The three novel aspects • Scalability: the 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.

5. Scope of the project from SGAM perspective

6. Expected beyond state-of-art progress • Fully defined interface specifications for TSO-DSO information exchange interfaces based on Use Case analysis and IEC 61970/61968/62325 standards to support highly automated information exchange and network analysis. • Fully defined interface specifications for information exchange between DSOs and market participants based on Use Case analysis and IEC 61850 and IEC 62325 standards to support highly automated information exchanges.

7. Expected beyond state-of-art progress • Role-based access control that securely accommodates new data requirements and unbundling processes. A specified suite of ICT protocols and integration with the defined interfaces. • Proof of Concept using field tests and demonstration with industry specification at both TSO and DSO levels.

8. Use Case development methodology • Formal description of 10 TSO-DSO Business Use Cases (BUCs) which can have several scenarios (business options).

9. Use Case Management Repository • Repository will be used across work packages

10. Deployment, Testing and Evaluation of DSO-TSO interaction using Scalable and Secure ICT Tools • Use cases, process, methods and techniques obtained in other work packages are transformed into a series into a series of TSO-DSO demonstrations, trials and field tests. • Demonstration in Slovenia: ELES, Elektro Gorenjska and EIMV • BUC: “Activation of DSO-connected resources for balancing purposes in market environment” • BUC: “Coordination of long-term network planning between TSO and DSO”
