Communications Architecture Principles

2. Direct• Currently Internet (AutoDR for C&I) or

legacy technologies (Residential PCT)• SCE-provided (Gateways) or layered on

top of customer technologies/services (e.g., Security, Cable, etc.)

• OpenADR 2.0b and SEP 2.0 (DER and others?)

1. Third Party• DR Aggregators, Cloud Providers • Currently Pay for Performance

(Residential) or Capacity Bidding, RTP, etc. (C&I)

• OpenADR 2.0b, Green Button, SEP2 (DER and others?)

3. 3rd Party Communications• Transparent to SCE• Customers contract with 3rd parties for

Services• Residential and C&I

Agenda

• Summary Strategy• Summary Vision• Services Model• Illustrative Implementation• Data Sharing• Questions / Comments

Summary Strategy

• Assumption: Velocity of market outpaces Utility cycle time.• Result: Technology evaluation treadmill.• Good Enough strategy to monetize now, so we can shift from

Technology discussions to Customer discussions.• Allow us focus on customers’ needs.

Summary VisionCustomer‐Centric:• Focus Groups for needs. No longer claim, “I, too, am a customer”.• Self enrollment ‐ decouple wiring from connectivity.Network aka Connectivity Plumbing:• Connectivity premise:

– No ‘silver bullet’– Pros and Cons to any solution

• Diversity is key:– Support multiple transceivers (modular SGD’s begin to make sense).– 80/20 rule, majority of customers at minimal expense, ie:

• 40% WiFi• 40% Cellular• 20% cannot serve (…yet OR with additional customer funding)

– Universal program socializes high cost of the 20%

Services Model• Decouple transceiver from functionality

– Conventional Wisdom is to deploy a solution (ie DR device).– Future IoT provides connectivity, with optionality to use in multiple ways.

• Example, a water heater (because we all have one):

• Offer carrots over financial incentives…? Will customers demand?• Utilities facing significant Intellectual Property opportunity.

App Description

1 DR Shed is economic over next best alternative

2 DSM Also buy an EV? Push Choreograph Load app

3 EE Put your house to sleep when vacant

4 Safety Legionnaires disease (ie 140 for 1 hr/day)

5 Health Equipment health, reminders ie drain

6 Alerts Burst pipe, freezing temp

7 Key… Innovative ways

Illustrative Implementation

Broadband

Duke AP

Cannot serve w/o customer financial participation.

Ie Diverse technologies even in a single home.

OFMB

Data Sharing• Duke actively quantifying Broadband

– Ethernet network logging, as a baseline.– WiFi logging by appliance (3 mos WH, HVAC, Pool, garage)– Key = creating a Duke analytical engine to interpret data

• EPRI expressed similar interest for Cellular• Early learnings:

– Always on or mostly on?– Support call router swap– AP’s require rebooting (interval?)– Customer perception (slow?)– Predictable on/off‐peak times

• Please share your findings

VirtuGrid enables data (voltage, power, energy readings, GPS location, phase and circuit connectivity) to be sent from the remote location to the substation over the same path as the power, enabling remote awareness of the grid and enhancing its value. VirtuGrid facilitates control and timing of remote communications with multiple types of standard down line communication networks with very low bandwidth usage.

The result is an integrated physical and electrical mapping of the primary and secondary circuits of your distribution network.

GIS brings significant benefit to the distribution grid but it is limited to mapping visual assets to geographic coordinates.

The distribution grid connectivity related to substation to customer power connection is poorly represented and inaccurate in most distribution systems.

VirtuGrid can record full three phase “normal state” customer to substation maps and compare with abnormal state to determine connectivity.

Customer and equipment can be tracked as they move from one circuit and phase to another circuit and phase and the operators notified by the alarm system.

This information then is serviced to the ADMS Model, OMS information and other key applications.

The Complexity of the Distribution Asset

Management and Mapping of a Distribution Assets

• Change volume of assets on distribution is significant

• Common to re-configure distribution connectivity

• Significant change in assets for large storm restoration

• GIS tracking of assets does not address electrical connectivity information

• Distribution GIS systems have significant data problems because of volume, age, size, and location

Grid location and power backhaul:

VCU Application for Chiller Plant

Available for both Network and Radial Grids.

Backhaul of power and other data fromspecific remote points within the distributiongrids where other communication backhaulmethods may not have coverage or may notbe reliable.

Non AMI existing meters can be used withremote collection and monitoring of powerdata.

Provides portable remote devices that can be plugged

into low voltage secondary points at the customer

location and manually map the customer connection

to the substation.

Replaces field resources used to manually track

connectivity across the grid with a 5 minute test being

execute by a portable device at the customer location

being validated.

Correct connectivity information prevents false truck

roles during restoration and poor response to

customer outages that are not mapped to the correct

grid connectivity and location

Summary VirtuGrid System Characteristics

The Remote connections for VirtuGrid are all on the low voltage (120, 240 volt) side of the Grid. There is no primary equipment required to implement VirtuGrid Communication and Mapping.

The FIM receiver connections for the VirtuGrid are all on the low voltage side (extremely low burden auxiliary current transformers attached to the standard metering or relaying secondary current transformer circuits.

The VirtuGrid engine is the network of remote sensors that communicate specific information on a scheduled basis from the edge of the distribution grid to a central database where it is converted into a serviceable base of data that maintains the accuracy of the distribution grid connectivityand tracks the electrical state of the distribution grid.

The VirtuGrid is broken down into a Domain structure to match the distribution grid characteristics. One Domain represents all of the connection points tied to one substation electrical bus. This Domain is a substructure of the distribution grid. The VirtuGrid Server will handle multiple Domains and detect changes between these separate domains using the remote sensor network.
