Connecting Generation to Distribution: Technical Challenges
Radial system: Distribution system not designed to connect multiple generators - bi-directional power flow
Rural Feeders: “long, weak, light” – voltage issues
Technical Limits: Protections & system limits; Transmission capacity
Model & Tools: Steady State; Dynamic study
Transmission Constraints: TS back-feed, DGs not market participant
Tx/Dx Code Overlap: How does this work?
Evolving technical impacts/solutions: learning continues
10
Dealing with Technical Challenges:
Engage internal & external technical experts on complex issues and
universities on R&D matters
Work with the Independent Electricity Systems Operator (IESO) and
Ontario Power Authority (OPA) on Transmission impact (reverse flow)
Continue to better understand technical impacts of integrating large
amounts of renewable DGs
Work on Smart Grid & other demonstration projects to further
facilitate renewable generation connection and to transform the
distribution system to address customer needs
11
Advanced Distribution System (ADS) Initiative Purpose
Modernize our distribution system to better serve our customers
Pilot underway to identify, deploy, analyze, and assess equipment and applications
Builds on Smart
Meters and WiMax already deployed
