Grid Optimization in an Uncertain World
Electric Utility: Con Edison of New York Smart Grid
• Enabling integration of Distributed Energy Resources at the ISO and Utility level to improve reliability in System Operations
• Providing granular level Machine Learning based load forecasting, power flow simulation, threat simulation
• Optimizing the use of distributed resources to address capacity constraints on transmission and distribution system
• Providing coordination and scheduling
for Distributed Energy Resources
The goal of the Con Edison DOE Smart grid project is to deploy smart grid technology within New York City and demonstrate its ability to integrate and optimize distributed energy resources (DR) to enhance efficiency, reliability and economic savings for the Utility and End Users alike.
ConEdison of New York Smart Grid
Threat Simulation - Reliability
Control room operator needs to know– What is the next worst thing that can happen? – What is the most likely thing that will happen?
Solution– Control room and operational decision support
system for detection of variances in equipment performance and prediction of unreliability
Value– Improved reliability of service through predicted
vulnerabilities and preemptive actions
Smart Grid Deployment – Con Edison
• Triple the effectiveness of capital deployed for cable replacement – Improve Reliability
Solution•Combined 200 Attributes
•Static and real time data•Machine Learning based pattern recognition•Rank the susceptibility of cable failure.
Electric Industry
Challenge/Opportunities• Reliability• Fair return on assets• Uncertainties
– New Distributed Energy Resources• Wind, Solar, electric plug-in vehicles,
micro-grids, demand response– Stranded electric infrastructure costs– Competition
• Sustainability mandates– Environment and climate
• Energy Efficiency mandates/incentives
Why Smart Grid? - Being a better manager of assets and power flow from DER via intelligence holds promise of addressing the above
Building/City/Campus
Challenge/Opportunities• Reduce costs• Reliability • Distributed Energy
Resources• Environmentally friendly
electric supply – Solar, Wind• Efficient/reliable/secure –
Micro-grid• Demand Response for higher
utilization/efficiency• Customer Choice –
Reliability/Cost/Supply Type• Monetize infrastructure
through interdependency
• Sustainability– Environment and climate
Micro-grids hold promise to transform power distribution, enabling new levels of system reliability and efficiency

Focus on: Microgrid IntelligenceSelf-healing• Responds to system disturbances
automatically• Capable of operating as an “island” off
of the regional grid
Self-coordination• Coordinates real-time demands of
energy users, distributed resources, microgrid operations and distribution system integrity
Self-scheduling• Schedules dispatch of distributed
energy resources using decisioning tools to optimize overall grid operational performance
Smart Utility Management
Improves energy efficiency and asset management using intelligence via an Integrated System Model (ISM) based decision support Integrated System Model of entire building’s energy infrastructurePrime focus on maintaining comfort of tenantsEnable direct control of tenant energy costsDrive pricing of commodities and infrastructure costs to the individual assetEnable behavioral changes based on pricingProvide an efficient way to diagnose anomalies in the operation of assets Initiate workflow for tasks needed to drive energy efficiency and asset management
Smart Utility Management
• Asset Management – Prediction/Optimization• Incident Management – Prediction/Detection• Electric Power Management – Prediction/Pricing• Sustainability improvement – Prediction/Incentive• Demand Management – Prediction/Incentive
Research, development, demonstration, and deployment of Smart Grid provides one of the greatest opportunities to improve modern society and create a sustainable environment through management of energy.
