EU-SysFlex blog: New ways of energy data exchange demonstrated


EU-SysFlex project has completed all the demonstrators dedicated to data management and results were just disseminated in a webinar – please visit webinar website to have access to the recording and presentations.

This blog summarises the key takeaways of several data exchange demonstrators whereby the common denominator is easy access to data and market through interoperable cross-border and cross-sector data management arrangement.

To ensure interoperability of flexibility services one needs to focus on data interoperability next to harmonising regulatory/business processes. Therefore, the system use cases designed for “Flexibility Platform” address the issue of homogeneous and secure data management through the concept of Data Exchange Platform. Proper data management contributes to the participation of stakeholders across the geographical borders and of any asset.

“Affordable Tool” in the role of FSP enables to bring smaller customers actively to the energy market willing to sell flexibility by aggregating such customers, consuming data services provided by DEP, and using market services (e.g. bid submission, asset activation) provided by the Flexibility Platform.

Residents of one country are able to access their meter data and share the data with other stakeholders using services (e.g. consent management) provided by DEP located in another country, it is possible to remove barriers from accessing meter data from different organizations in different countries. The biggest obstacle of cross-border data exchange is differing level of authentication available in different countries, however this is being solved within scope of eIDAS (European Regulation on electronic IDentification, Authentication and trust Services).

Data providers and data users connected to different DEPs (ECCo SP, Estfeed) can exchange data by ensuring interoperability of DEPs. This was demonstrated for private data sharing use case whereby on platform benefitted from consent services provided by another platform. The demonstration was able to add value to ECCo SP by using the consent checking capabilities of Estfeed which allowed it to validate that the application behind ECCo SP had data owner’s consent to receive some private data.

Using dedicated privacy-preserving technologies (Sharemind in this case) it is possible to preserve data owner’s privacy while allowing a third party application (Flexibility Platform in this case) to receive a calculated result based on such private data (calculation of Flexibility Service Provider’s baseline in this case). Use of DEP (Estfeed) ensures that the data owner is aware that the data is used for just given (baseline calculation) purposes but in a privacy-preserving way.

Cross-sector data exchange was demonstrated which proposed a way to add value to users of one system (meter data hub) with data enrichment from another system (building register). The demonstration showed that if the two systems have not been intended to exchange data then sometimes it can be difficult to reliably link the data – the quality of ‘customer address’ was much lower in one system than the other.

DEP can transport to any third-party application results from big data framework, an end-to-end big data process was demonstrated: raw data are collected from external APIs, processed in batch and near-real time with AI algorithms, results are stored in a serving layer and are available through request/response API. This deployed architecture has worked properly at least within a context where the frequency requests were not high, with limited size data results and without specific latency constraints.

It is possible to integrate alternative signing mechanisms to the critical logs that provide the information about the data exchange and participants. The risk of losing critical data logs was reduced from the three aspects: a) signing with different technology; b) adding additional log storage; c) including anti-tamper infrastructure to an existing solution.

It would not take much effort to translate the original API of an implementation (e.g. “Flexibility Platform”) into CIM compliant API, and to replace already implemented original API by CIM compliant API.

Main contributors to demos were Estonian TSO Elering, Polish TSO PSE as well as technical solutions’ providers AKKA (France), Enoco (Norway), Cybernetica (Estonia) and Guardtime (Estonia).

Enoco is a private enterprise established in 2009, and has specialised on developing andimplementing energy efficient Building Management Systems. In addition to optimising thetraditional technical systems like ventilation, heating/cooling and light system, Enoco has developed unique energy control systems for large and medium buildings. Enoco has developed a unique power-peak control system, where all consumers in the building are established with its pre-defined priority – applied to disable or enable it during power demanding periods – ensuring that the total power outtake and energy consumption of the building does not exceed predefined limits.Furthermore – Enoco has developed a cloud based Energy Surveillance/Monitoring System (EMS).
