Traditional SCADA/EMS Environment
• Includes transmission networks that • Includes transmission networks that traditionally have a high level of automation and control
• Focused on generation and transmission facilities due to emphasis on system stability and p y ycoordination with ISO/RTOs
• All advanced applications cater to transmission modeltransmission model
• Outages typically impact a large area• Transmission operators are removed
from Distribution System operations

SCADA/DMS Environment
• Distribution networks are larger and more spread out than Transmissionmore spread out than Transmission
• Impact of an outage in Distribution is localized and affect a small number of customers

SCADA/DMS: Operations Environment
• Will include a distribution network that will have a high level automation and will have a high level automation and control
• Focus on distribution network due to consumers and regulatory agency consumers and regulatory agency pressures
• Basic and advanced applications that t t th di t ib ti tcater to the distribution system
• Distribution operational systems will have impact to transmission operations
• Integration to other infrastructure technology such as smart meters and gyDA field devices

SCADA/DMS: Single vs. Multiple Vendor Approach
Category Considerations Single SCADA EMS/DMS(1 vendor/1 DB for T&D)
Separate SCADA/EMS & SCADA/DMS (one or more vendors)
Common T&D SCADA & Separate DMS Apps
(one or more vendors)

Requirements for Transmission System
Combined systems; requirements apply to both T&D

Integration Risks EMS-DMS interfaces, external systems
One T&D database and system; less risks
Need to tightly integrate several functions; medium risks
Need to tightly integrate several functions; higher risks
Implementation Costs Increased implementation costs because of separate
implementations
Cost efficiencies associated with single implementation
Increased cost because two separate implementations; could still leverage
some folks across both

Support Costs Increased support costs because of different systems

Control Center Management: Benefits
• Single operational environment for Operators/DispatchersOperators/Dispatchers
• Integration of SCADA/DMS/OMS to enable seamless dispatcher work enable seamless dispatcher work flows
• Integrated dispatch functions and g proles gives utilities the option of creating a “true” single Distribution Dispatcher
• Integrated dispatch functions and l i t l t roles give control center
management flexible staffing options• Enables a paperless operation

Distribution Dispatcher
Integrated dispatch functions and roles gives utilities the option of creating a true Distribution Dispatcher……
• Dispatcher roles not defined by systems
• Opportunities for staffing level changes
• Common operating • Common operating processes and procedures
• Training curriculum designed for one dispatch role

Dispatch Flexibility
Integrated dispatch functions and roles give control center management flexible staffing options……
• Elimination of working in silos
• Flexibility of covering absences
• Move dispatch resources for Move dispatch resources for system events
• Combined simulation i f di t h scenarios for dispatcher
readiness

What’s Important to the End-User?
Common Tagging
• Analysis for substation and feeder/circuit operations to check for tags in one system affecting operations in the other systemEasy verification of zones of protection that overlap systems
gg g
• Easy verification of zones of protection that overlap systems
Ability to Pass Status and Analog Information
• Updated network connectivity based upon real-time SCADA events and automated devices
• Quick access to analog readings for planned or emergent switching • Quick access to analog readings for planned or emergent switching
Reliable Closed Loop Operations
• Fault Location Isolation & Service Restoration (FLISR)• Integrated Volt Var Control (IVVC)

What’s Important to the End-User?
Integration of Systems into a Single Environment
• Increased efficiency with one system, eliminating the need to access multiple systems
• Elimination the need to access multiple systems with potentially different data
Seamless Access to Schematic and GIS Maps
• Optimizes efficiency when executing multiple load transfers

Conclusions
• Significant activity in Distribution Operations by utilities and vendors –driven by Smart Grid and improvements in technologies
• SCADA/DMS are under evolution – these systems have real-time needs as in the traditional Transmission sideneeds as in the traditional Transmission side
• Advanced DMS applications are being developed/implemented • Utilities and vendors are driving toward an Integrated user • Utilities and vendors are driving toward an Integrated user
environment – processes are being reviewed and re-designed • Detailed analysis of single vs. multiple SCADA/EMS/DMS vendors is y g p
critical• Integration of systems are complex (DA, AMI, EMS, OMS, etc.)• Multi-phase approach may be desirable to dry run apps prior to full
implementation
