The new Distribution world

Challenges/opportunities

– New functionalities (DER, micro-grid)

– New technologies (mobile, sensors, AMI, intelligent relays)

– New expectations (regulatory, customer)

Aspirations

– Accurate fault location, isolation and service

restoration

– Empower field crews with useful tools

– Manage and proactively leverage the benefits of DER

– Energy efficiency improvements of advanced

Volt/VAr control

– Asset management to prioritize expenditures,

improve reliability & reduce maintenance costs


Lots of types of data support the aspirations…

…we’re focusing on geospatial and grid model data

Utility-owned grid asset data

Field data

– AMI readings, load

– Real-time measurements, multi-second and sub-cycle

Geospatial data

Non-utility owned asset data

Non-grid asset data

– Protection assets

– Communications assets

– Cyber security assets

Grid model data

Field device configuration data


We’re focusing on grid model data because…

It underpins functions using simulations

• Outage management / planning

• Expansion planning

• Protection design

• Power quality analysis

• FLISR

• DER management

• Volt/VAr optimization

It provides input to other critical functions

• Field crew enablement

• Generation control

• Effective asset management

• Load forecasting

• Visualization


(Distribution) Grid models are derived from GIS geospatial data

What is grid model data?

Represents grid electrical behavior characteristics and state

Data representing a simplified view of the electrical grid, including

equipment, its electrical behavior and its connectivity, as well as its

operating state at a moment in time, that is sufficient to describe a

starting point for network analysis.

Input to all sorts of network analysis and simulations

– Steady-state power flows

– Dynamics (sub-cycle) study runs

– State estimation

– Contingency analysis

– Short circuit

– Outage detection (unplanned) and definition (planned)

– Operator training simulators


What is grid model data?

Used across Planning, Operations, Protection and Market

domains

Comprised of two main parts

– Physical network model - grid equipment electrical behavior and

connectivity

– Operating assumptions - snapshot of the ‘state of the grid’ at a

moment in time (breaker states, loads, generation)

Usually consumed in cohesive subsets

– Simulations require collections of data that ‘make sense’

– Simulations need only part of the model

Can require simplification

Typically has multiple sources

Grid model data is both complex and important

There is only one grid

But…. different consumers want

– Different parts of the system

– Different types of data

– Different levels of detail

– Different system states

– Different points in time

Distribution– Inconsistently from utility to utility

– In ad-hoc, often unrecognized silos

– With missing and trapped data

– New one-off data exchange solutions being created for multiple new

classes of applications

– For a vastly larger number of electrical grid elements

Industry impact

Industry impact

– Have Network Model Management architecture, supported by IEC

Common Information Model standard

– There are now viable network model management tools

Dramatic improvement over last 2 years

No one vendor ‘has it all’ yet, but several are getting close

EPRI “Network Model Manager Technical Market Requirements”

document used as basis for RFPs

– Increasing utility interest



Observations on Distribution network model management

Problem similar in T and D

Slide from 2014 AEP NMMI program

presentation

Slide from John Bubb’s ‘Architecting the

Future Grid’ presentation (2016)



Huge overlap in requirements between T and D

NMM functional requirements

(from “Network Model Manager Technical Market Requirements” )

1. Enable management of Physical Network Model parts, which

contain data representing electrical capabilities of physical grid

elements

Model Parts are an entity’s representation of a portion of the

electrical grid

Model Parts fit within a framework of boundaries

Model Part versions include current as-built and go back into

history

Potential changes to Model Parts expressed in terms of Projects

2. Provide Object Registry services, to create and maintain the

mapping of network model objects among various systems

3. Support for Workspaces, in which multiple users concurrently

carry out NMM operations in their own environments






4. Provide Graphical User Interface capabilities, which support

viewing and editing via schematics, object detail, tabulars

5. Support model and case assembly, according to the CIM 61970

modular conceptCase = physical network Model Parts + Projects + state assumptions

6. Perform model validation, at multiple levels from basic data entry

checks to power flows

7. Support external integration, via CIM interfaces

8. Have model-driven configuration, where schema of stored,

imported and exported data is defined by an information model






9. Use engineering design (asset connectivity) detail as input,

storing engineering design data and to hosting computation of

circuit impedances and ratings from detailed line information or

transformer data

NMM functional requirements are

independent of hosting system choice



Some differences

– ‘As-Constructed’ vs ‘As-Operated’

Artifact of earlier constraints

Difference is simply collection of ‘temporary changes’

Applications often need both

– Importance of field crews

Best source and ultimate consumer of network model data

Enablement should be high priority

– Geospatial models vs network models

Geospatial models – physical asset locations and connectivity

Network models – state of grid from electrical behavior perspective
