Coordination of Transmission and Distribution data eXchanges for renewables integration in the European marketplace through Advanced, Scalable and Secure ICT Systems and Tools

Periodic Reporting for period 2 - TDX-ASSIST (Coordination of Transmission and Distribution data eXchanges for renewables integration in the European marketplace through Advanced, Scalable and Secure ICT Systems and Tools)

Reporting period: 2019-04-01 to 2020-09-30

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.
Aim and objectives of work performed in Technical Work Packages 1-4

Work Package 1 - ICT tools and applications to enable Greater TSO-DSO Interoperability
Aim and objectives: Define information management requirements for secure and efficient information exchange. Augment existing operational, system and business use cases with new cases. Specify processes for exchanging and validating reduced grid models in a standardised manner. Recommend standardised approaches for information exchange and data communications.

Work Package 2 – Data Management and Exchange for Market Participant Interoperability
Aim and objectives: Documentation of the technical interfaces and services in the project, their corresponding standardised data models, non-functional requirements such as security, reliability and interoperability and the assessment of the improvement achieved by the technologies used in the project. A maturity model will be introduced and this will lead to the definition of KPIs to assess the project outcomes.

Work Package 3 – Multi-Actor information and Data Access Portal to enable Business-to-Business Processes
Aim and objectives: Develop interfaces into a scalable and secure ICT infrastructure that gives access to a wider range of stakeholders as appropriate to power sector data. Specify a data-access portal using a cloud-based approach. Create a comprehensive set of use-cases for the data-access portal and specify time and space scales of data in order to ensure fitness for purpose.

Work Package 4 – Deployment, testing and evaluation of DSC-TSO interaction using scalable and secure ICT Tools
Aim and objectives: Use cases, processes, methods and techniques from WP1-3 are transformed into a series of actual TSO-DSO demonstrations, trials and field tests, which are subsequently evaluated. Evaluate the project impact in terms of TRLs and KPIs as defined WP1 and WP2. Perform a stakeholder analysis considering WP3 in order to demonstrate the data-access portal for a range of use cases involving selected stakeholders.
The TDX-ASSIST project focused on TSO-DSO interoperability. While TSO-TSO interoperability is currently well established by ENTSO-E through implementation of the Common Grid Model Exchange System, TSO-DSO interoperability will also benefit future TSO-TSO interoperability. In this context, the project also considered DSO to other Market-participants (DSOs, Aggregators, Distributed Energy Resource Operators, Micro-grid Operators) and information or data access portals that enable business processes involving relevant actors in the electrical power sector.
Beyond state-of-the-art progress that was achieved includes:
• 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.
• 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.
