Study Parameters
• Dr
Eliminating this separation (where practicable) OR
splitting the feeder spine and doubling Dr conductor
allows the installation of SN Type 3; which combines
islanding with reclosing enhancing the entire OH
feeder availability, and significantly reducing the cost
of modernization.
• Dm
Eliminating this separation (where practicable) allows
merging 2 SN significantly reducing the cost of
modernization.
• Transformer Size and Location
Part of this project it is proposed to evaluate the need for a
second LTC transformer inside the main substation versus
smaller size transformers closer to the load. The study should
include a cost analysis and techinical evaluation of any
benefits to the stability of the network.

Smart Node Operation – Within Load Perimeter
• Smart Nodes shall use the Integrated PQM sensing to establish at short intervals
the state of the Gen-Load:
• Generating: based on threshold set by a central system
• Self-Sufficient
• Shortage
• Smart Nodes shall not operate a switching scheme except under one of the
automation schemes employed.
• Smart Nodes can subscribe to Thermostat, Solar Meter and Revenue Meter at
long intervals to access the long term behavior (forecast) of the gen-load (i.e.
expected state)

9. Bassem Maurice – Oct 19, 2015
Smart Node Operation – Over Network Perimeter
• Smart Nodes shall publish Integrated PQM sensing data over Abstract Bus
• Smart Nodes can be polled via Any SCADA Protocol for Integrated PQM
sensing data.
• Smart Node Type 3 shall operate autonomously to maintain supply to load from
either source.
• A central system shall set based on Smart Node data and load flow calculation
the Rate (dollars) associated with the generating load at a particular interval.
• Smart Nodes can subscribe to each other feeds.
• A central system shall inform each node the expected (forecasted) state of all
nodes on the system at a particular interval.
• A central system shall set the automation mode for each node.

10. Bassem Maurice – Oct 19, 2015
Smart Node Automation Modes
• Forecasted Automation
• In this mode Smart Nodes shall operate based on thresholds and forecasts set by a central system in
order to:
• Maximize Energy Efficiency
• Minimize cost of energy based on Rate (dollars) at each generating node
• Distributed Automation
• If enabled; in this mode Smart Nodes shall operate autonomously or based on Node2Node
communication in order to:
• Ensure minimal supply interruption
• Central Automation
• In this mode Smart Nodes shall operate only in response to commands by a central system.
