Fingrid is the Finnish transmission system operator (TSO)

We are responsible for the functioning of the entire power system in Finland. We keep the transmission grid in a good condition and construct it on the basis of the needs of the electricity market.

We transmit electricity continuously from electricity generating companies to distribution network companies and industrial companies. 75% of the electricity in Finland is transmitted in our grid.

We take care of the cross-border connections of electricity transmission. There are direct connections to Finland from Russia, Sweden, Norway and Estonia.

We promote the functioning of the electricity market by keeping the transmission connections between various countries in working order.

Fingrid Oyj’s grid assets:

•14,300 km of transmission lines and cables

•113 substations

• 67 power transformers, with total capacity of 21,000 MVA

• 935 MW of reserve power capacity



ELVIS high level objectives

• Increasing operative efficiency

• Increasing proactivity in calculations, monitoring and maintenance

• Single source for power system information

• Improving information access and usability within stakeholders

• Adding cost aspect to operation and power system components

• Enhanced business planning through cost operational analytics

• Platform for further system development with modern solutions

• Mobile solutions and data analysis to support Asset Management and Power system operations

A more efficient tool for Fingrid's asset and operation management by replacing existing tailor-made grid information systems by integrated best-of-breed standard software products

ArcGISMaximo Integration – Main Separation of Responsibilities

• The split of responsibilities between ArcGIS and Maximo are captured by the CIM PowerSystemResource-to-Asset relationship

• Maximo does not model network connectivity.

• Rather, Maximo structures its locations hierarchically, which maps directly to ArcGIS (CIM) containment.

Processing

• ODMS functions as the bridge between the node/breaker operational model and the bus/branch planning model.

• The mapping is bi-directional. The backwards mapping is used to represent calculation results in ArcGIS and Maximo.

GIS–>ODMS – Bridging Node/Breaker and Bus/Branch Models



GIS–>ODMS – CIM Mapping

• The GIS Powergrid model is a CIM adaption, but must still first and foremost serve as a GIS network model. By contrast, ODMS is a pure CIM-based system.

• Thus, mapping of the connectivity model is a necessity. Particular complex details include:

- Mapping of switches from a point feature into a two-terminal device.

- The necessity of creating abstract elements (Terminals and some ConnectivityNodes) out of a more crude model.

Versioning Challenge


Original plan:

• Choice of degree of freedom – users are allowed to make mistakes.

• An ArcGIS version is selected, along with a compare project residing in ODMS. The diff between these two are loaded.

• Commissioning of projected versions into base model synchronized through business processes.

• One phase of project sent at once

Challenges:

• Version hierarchy, reconcile process, performance, base model integrity

Mitigation:

• One über version created nightly (basemodel + selected versions) for CIM model updates

• Only one version is sent: better performance, perfect base model integrity, no conlicts with otherprojects due to reconcile


Central Grid Model Management Supporting All Processes

• Master current grid model originates from GIS

• Nameplate electrical values are synchronised from asset registry

• Grid model is tranformed to CIM model and imported to CIM network modeldatabase

• The network model is updated with some simulation specific data

• The central network model can be used in different programs:• PSS/O, PSS/E, CAPE, hEMS (future)

• and for different purposes• power flow calculation, state estimation, contingency analysis, short circuit

calculation, dynamic simulation

ELVIS will bring Fingrid new things

• Common grid model which is synchronized with asset management, operations planning, long term planning and network protection analysis

• All switch gear modeled with real and accurate description of components in the grid. Lot's of additional information about the grid model.

Common accurate grid model

• Accurate planning grid model linked to real time status and metering data.

• Preparing of calculation model is easy by using status and metering data from the past.

Better utilization of saved measuring data

• Attributes for grid components available through the map

• Visualization of real time power and voltage measurements using colours on grid model or map

Better visualization of data, grid status and results

• Common database about future projects where schedules are in sync through the systems

• Easy to build different scenarios

Feedback to CIM

• HVDC missing from schedules• schedules vs. basemodel terminal connected atribute

• In or out of service – only on Terminal

• Overlapping attributes on for example GeneratingUnit: nominalP, maxOperatingP, ratedNetMaxP, ratedGrossMaxP



Considerations with CIM integration

• Full model exchange vs. incremental exchange• model integrity vs. performance

• Extensions like AMS location id can significantly improve usefullnessand further integration possibilities. By sacrificing use of only CIM URI for identifier, CIM model can be made lot easier to integrate withexisting systems and can actually promote CIM to other systems as CIM id can then be made available to those systems



Fingrid's next steps with CIM 2015-2016

Further development planned to fulfil ENTSO-E CGMES needs

• planned grid outages automatically to network model

• planned powerplant outages automatically to network model

• forecasted load and generation automatically to network model


Further CIM integration planned to automatically update

• Grid model from ODMS to EMS/SCADA simulator / state-estimator

• Measurement mapping from PI historian to ODMS
