. .• Every tool requires its own network model, in its own format

• Every tool has its own users and maintainers

• Silos are both technical and organizational

Transmission Network Model ManagementIn Support of Reliability

• Silos cause:

– Duplicate effort

– Synchronization problems

– Consistency issues

– “Trapped” data

Transmission Network Model ManagementTechnical & Organizational Silos

Lots of energy invested in unproductive workErrors can go unrecognized

•Silos at multiple levels – TSO, ISO, Interconnect

Network Analysis

Planning

– ERCOT model management implementation

– Product configuration tools

EMS

– Network model interoperability tests started in 2000 –more than 15 to-date

– Planning (bus/branch) model added in 2008

Transmission Network Model ManagementSupport from the CIM

– Began as operational model in early 1990s

– Support EMS components from different vendors

– Became IEC Standard in mid-1990s

– Understood as basis for semantic model for enterprise integration

– Dynamics (transient behavior) model added in 2013

– Projects, outage and contingency modeling are current topics

•Common Information Model (CIM) as foundation

Now nearly robust enough to truly support NMM tool integration

NMM Requirements Overview ProjectNMM Functional Overview

Mission: Support the IEC CIM framework concept for assembling EQ Model Parts

• This is the top layer of the case diagram.

• PN part retrieval is the first step:

• EQ Model Part selection & loading

• EQ Project selection & loading

• Additional PN Model Parts as desired

• Validation against framework specifications• Optional: built-in and/or locally-written services

(simplification, mesh equivalents, etc.)

Mission: Support concurrent modeling activity by multiple users

• Multiple users – each has a private workspace

• Two primary purposes:

1. To support user browse and edit of Model Parts.

2. To support assembly of base cases for export.

• Supports functions

Mission: Support the IEC CIM modular concept for assembling network analysis base cases

• Starts from a composed set of PN Model Parts

• A complete SSH must be assembled for the PN extent. This has a number of relatively independent sub-parts:

• Status of devices• Regulation by controls• Monitoring limits• Energy in and out

Mission: Support integration with NMM without impact to the core NMM product

NMM shall be ‘integration ready’:

• CIM import / export of individual Model Parts and Projects

• CIM import / export of assembled models and cases

• Integration processes can invoke NMM services, such as stored procedures

• Name translation via object registry services

• Consistent approach to transformation to and from external formats

Mission: Assure high quality source material for network analysis

Validation must be supported at the following levels:

• Consistency with standard CIM forms

• Reasonability checks

• Including the ability to create custom validation logic

• Algorithm based tests

• Topology processing service

• Power flow service

• Testing procedures

NMM Requirements Overview ProjectValidation Requirements

Mission: support utility extension of the core Canonical Data model without modification of the core NMM product

NMM provides facilities for extending and updating the Model Part schema such that:

• Model Parts in the previous schema are transformed to the new version

• Core product functionality of the NMM adapts to the new schema without modification of the product.

• i.e. The NMM is model driven!
