sce smart grid use cases
SCE Smart Grid Use Cases

Southern California Edison developed extensive use cases

We feel these should be brought to 4g’s attention

These use cases and their requirements can be useful to 4g in developing the baseline and standard


Some of the use cases apply directly to AMI, some are broader Smart Grid

Cover all, as the broader context has implications for AMI

different classes of response
Different Classes of Response

Fast - roundtrip within mSec over large dist.


Medium - (re)actions in 30 sec timeframes

Operator involved, machine assisted

Confidence/Corroboration of data needed

Slow - actions within hours to days

different classes of security
Different Classes of Security

High - affects grid stability (real time)

Confidence/Corroboration of Data

Medium - sensitive mid term data

Sensitive data showing typical grid operation and exposing vulnerability

Low/None - stored/post analyzed data

use case categories
Use Case Categories

Building and Customer Service

Customer Interface


Energy Procurement

Field Services and System Recovery

Installation and Maintenance

PEV - PlugIn Electric Vehicles

building and customer service
Building and Customer Service

Multiple Clients Read Demand and Energy Data Automatically from Customer Premises

Remotely Limit Usage and/or Connect and Disconnect Customers

Detect of Tampering or Theft at Customer Site

Contract Meter Reading (or Meter Reading for other Utilities).

Utility Side

Collect consumption information from meter (available at multiple points from meter to the back office)

Routine move-in, move-out, disconnect - lack of payment, connect - payment resumed, disconnect when load exceeds customer allowance

Detect potential theft of services, tampering liability concerns

Support of non-electric advanced meters (water, gas) on electric metering network

customer interface
Customer Interface

Customer Reduces Usage in Response to Pricing or Voluntary Load Reduction Events

Customer Access to Recent Energy Usage and Cost at Their Site

Customer Prepays for Electric Services

External Clients Use the AMI to Interact with Devices at Customer Site

Smart Appliance Use

Energy Mgmnt. Sys. (EMS) or In-Home Display (IHD)

Using Data for Targeted Mkting Campaigns

Analyses Using Load Researchers Data

customer interface cont d
Customer Interface (cont’d.)

Customer Side

Responds to request for load reduction

Evaluate energy spending and usage and make real time adjustments

Prepay for their or others accounts

Provides for third party control of energy consuming devices

Installs, configures, registers and uses device

Utility Side

Sends request for load reduction

Provides individual usage information

Device responds to information from utility

Offers programs to match customer usage scenarios/characteristics

Analyzes a variety of load scenarios - individual, group, segment, etc. to generate statistics for many (customer and internal) uses


Distribution Operations Curtails Customer Load for Grid Management

Distribution Engineering or Operations Optimize Network Based on Data Collected by the AMI System

Customer Provides Distributed Generation

Locating Outage Using AMI Data and Restores Service

Automatic Reconfiguration of Power System for Reliability

Distribution Operator Controlling Distribution System

Distribution Planner Optimizing Asset Utilization

Planners Performing Analytics Using Historical Data

Utility Managing Utility-Owned Distributed Generation

Field Worker Using Consolidated Mobile Solution (CMS)

Using Technology to Enhance Outage Comm. Processes

Utilizing Energy Storage to Balance Renewable Variability

Auto Trigger of FACTS Devices Using Phasor Data to Maintain Sys. Stability

Dissolved Gas Monitoring to Detect Emerging Failures of Transformer Banks

C-RAS Sys. Monitors Grid System Status and Exerts Control to Maintain System Stability and Prevent Overloads

Using Phasor Data for Grid Operation, Control and Analysis

Optimizing Transmission Throughput Using Dynamic Ratings

Using Monitoring Data for Condition-Based Maintenance Programs

Using “Data Beyond SCADA” to Analyze System Faults

delivery cont d
Delivery (cont’d.)

Utility Side

Request for future reductions (sometimes may be overridden by customer)

General network optimization

Integration of customer generated energy

Improved service restoration and reliability

Reduce manpower (CSR and crews) to service outages

Improved grid management/reliability

Provides DR (demand response) capability

Distribution transformer management (load, deploy, maintain, replace, etc.)

Asset inspection and planned/unplanned work assignments

Improved communication to customer during outages

Balancing/management of renewable with energy storage

Maintain system stability following a destabilizing event

Increased frequency of monitoring to optimize transformer utilization and take corrective action

Fast centralized response to system stability to enable faster tripping, load shedding or system configuration changes

Use post event system condition analysis capabilities to help prevent further/widespread events

Using dynamic rating of transmission lines and transformers to optimize the power throughput

Predict/determine transmission and distribution faults

energy procurement
Energy Procurement

Real Time Operations Curtails or Limits Load for Economic Dispatch (ES&M)
