Building a modern data stack to maintain an efficient and safe electrical grid
- 1. Building an MDM for a Data-Centric Organization with Neo4j An overview of how our organization transitioned to being data-centric, through the implementation of a Enterprise data backbone, and dedicated tools using Neo4j technology, as the various challenges we faced during the process to make the dream come true.
- 2. Who are we ? Elia Group is a frontrunner in the transition of the energy sector. As transmission system operators, Elia and 50Hertz lead the way for a successful energy transition in a sustainable world Cédric Charlier Head of Data technologies @EliaGroup Leydens Gaëtan Competency Leader (Data engineers) @EliaGroup Principal Consultant, and digital twin solution owner @Ordina
- 3. Our journey towards being data-centric started with a digital TSO program. Highlighting business opportunities enabled by Data/Digital transformation Notion of ownership highlighted the importance of governed data. The birth of the data backbone paved the way for a governed data approach. Digital TSO Program with a Data-Centric Approach Data Architecture Data Quality BI & Data analytics Master data Metadata Data operations Data Governance
- 4. Data Backbone Driven by capabilities - Materialized through components Master data mgmt Master data Component instantiates
- 5. Business challenge: strong foot print on Assets lifecycle
- 6. An electrical circuit is a graph Battery Switch Lamp
- 7. Multiple views on a single physical circuit Battery Switch Lamp Electrical view Cutset Cutset living room Living room Kitchen Cutset kitchen Main circuit Geolocation Switch location Electric wires Ceiling lamp Living room Spare Parts Bulb White switch Socket Black dimmer
- 8. Decentralized master data management Electrical view Cutset view Living room Kitchen Geolocation Spare Parts Schematic GIS system Warehouse system Load flow system Application Dataset Schematics Cutsets Spare parts Maps MDM Relations between the different layers
- 9. Use a topological lasagna to: • Frame datasets • Decoupling of datasets • Traceability of data changes • Ruled Interactions Cope with multiple versions of the Truth
- 10. Why Neo4j for our MDM ? Traditional ways of handling joins Traditional ways of handling schema Additional libraries
- 11. Define or import models with ease
- 12. Embedded semantic Embedded semantic Operational layer Assets layer Semantic & Business concepts Circuit breaker asset Operational circuit breaker
- 13. Source semantic and model
- 14. Visualisation and exploration of data
