The document reports results for Task 2.3 – Analysis of existing platforms for distribution and transmission system management aimed to analysing digital platforms for power systems and energy applications already available, in order to highlight how interactions and collaborations can be achieved between the INTERPRETER solution and existing tools.
This H2020 project is funded by the European Commission (GA No. 864360) and is made up of nine partners from Spain, Portugal, Greece, Denmark, Belgium and France.
INTEPRETER project is developing a modular grid management solution enabling DSOs to take advantage of an open-source digital infrastructure than can be feed with their own data (regardless information and data model) and run services a la carte. This establishes common interactions between system operators – using a semantic repository responsible for the harmonization of the different data sources – and enable the creation of new grid models based on the analytics provided as core services portfolio empowering collaboration between DSO-DSO and DSO-TSO, fundamental for the implementations of the next energy market options.
This report identifies critical aspects that may affect the interactions between INTERPRETER open-source platform and existing industrial solutions. To achieve this aim, a benchmarking analysis has been carried out with the objective of mapping today’s common solutions and possible interfaces with INTERPRETER. The document also includes a preliminary investigation of the digital platforms sector in power systems in order to delimit the topics of interests. Among all the existing solutions, only the ones related to distribution (DMS, ADMS, OMS, AMI) and distribution-transmission (EMS) interactions are considered. Starting from the state-of-the-art a smart grid architecture, the different layers of digital platforms are analysed.
A survey of the existing platforms has been conducted considering the technical features identified and some considerations about INTERPRETER interactions are provided with regards of applications. Twelve ICT solutions are considered and compared in the benchmark analysis; some relevant features (from technical sheet and public information) are compared, but platforms have not been installed and tested from a computational point of view. The report also deals with those aspects characterizing DSO and TSO solutions, bringing out peculiarities, differences and possible common points.
The document describes a brief analysis of existing platforms for energy distribution applications that has been carried out based on a benchmark analysis starting at general context of today’s solutions for grid monitoring and control and the identification of those solutions that fit best with INTERPRETER objectives.
The following platform categories have been identified for benchmarking:
- DMS – Distribution Management System
- OMS – Outage Management System
- EMS – Energy Management System
- ADMS – Advanced Distribution Management System
- AMI – Advanced Metering Infrastructure
- Data Driven platforms for new market services
For all these large-scale applications for grid and asset management commonly adopted by system and market operators, their main aspects of architecture, advantage offered (INTERPRETER context) and the services provide have been identified.
Smart grid platforms have been analysed considering the approach of the SGAM layers: business, functional information, communication and component layers. For each layer one or more features have been identified for the benchmarking.
- Business Layer: Customization of service and applications
- Function Layer: Applications and/or services available
- Communication Layer: Communication Protocol, API for integration
- Information Layer: Data Model/Ontology
- Component Layer: Scalability, Latency, Real time processing

From the benchmark analysis itself, the following conclusions have been obtained:
- RESTful web service in JSON format is the most common methodology for data exchange and seems to be a future trend.
- Common Information Model (CIM) appears to be the state-of-the-art for backend (control centre) data model interoperability.
- Concerning services and applications:
- SCADA/DSM-like suites enable DSO to manage all tasks from a unique interface, providing a very wide range of applications
- Interoperability and system operators’ interactions is a relevant service that could be provided by INTERPRETER
- CIM is the most adopted solution for control centres interoperability
- INTERPRETER portfolio is mainly oriented to network control and optimization, this could be a gap when considering new market options (demand response, ancillaries, EV management, local energy market, etc.)
- Data-driven platforms for novel energy market options are also available open-source
A brief comparison between TSO and DSO platforms allowing to extract the following considerations:
- Interaction of TSOs and DSOs with other operators are limited or missing
- Cooperation between TSO and DSO are foreseen for active and reactive ancillary services, as well as flexibility
- All DSOs are equipped with SCADA but only 60% of them have implemented DSM applications
DSOs are expected to incorporate market-oriented tools in their platforms, due to their new role in a full deregulated market scenario.
