Progressing towards the DSPP

May 28, 2014

The Foundation for the Platform

SCADA on only 52% of substations

Areas of low customer density > 50% of Distribution Line

miles are 5kV Radial design with limited

Feeder Ties Limited communications to

field devices.

Energy and Outage Management System (EMS & OMS)

Upgrading existing EMS and OMS systems to ABB Network Manager Initial benefits of the common Network Manager platform:

Real time transfer of grid device status from EMS to OMS for optimization of outage prediction.

Integration of telemetered analog data from EMS to OMS to enhance situational awareness .

Provides a common platform to leverage future capabilities. e.g., Volt VAR Optimization, Unbalanced Load Flow, Advanced Metering

Infrastructure, Restoration Switching Analysis. Current forecasted go-live dates are:

NY EMS late 2014 NY OMS 2nd half 2015

Efficiency through Volt-Var Optimization

To be demonstrated on 7 feeders in RI Primary System Monitoring Centralized control of reactive resources &

voltage regulating equipment Reduce Losses Energy Use Reduction Voltage Performance Improvement Demand Reduction Improved Flexibility in meeting NE ISO PF

performance Improve Planning & Operations with increased

system performance monitoring

Expected Benefits (provided by vendor) 2.9% Energy reduction 30% Less voltage regulator tap operations Improved customer reliability through feeder

monitoring

DG Interconnections

DG applications are increasing and the MW size of requests are also increasing.

Anti-islanding protection via Direct Transfer Trip can be expensive and restrictive for circuit re-configuration

New technology being evaluated in Potsdam.

Other enabling efforts: The Fraunhofer Plug & Play Team DOE-FOA-479 Smart-Grid Ready PV

Inverter with Utility Communication

Microgrids

Potsdam Resiliency Based Multiple generators Multiple loads Resilient UG interconnections

Buffalo Niagara Medical Campus Realistic optimization

possibilities for power quality and energy efficiency will be identified throughout the power grid as well as within BNMC customer facilities.

Non-Wires Alternatives

Consideration of DER as a deferral option to traditional utility infrastructure expansion.

Custom Solutions: T&D Planning Engineers working closely with Customer EE and DR teams.
