L-10.1 DR owner initiated
The Purpose of DR
owner initiated function
is to
Optimize asset utilization by pricing
Industrial loads higher than normal during peak hours inorder to compensate for
more expensive generation utilised at those times
Regulating consumer and industrial loads in greater constrined regions to be
able to transfer power more efficiently
directly involving
DR operator
DisCo
RTO
Special Customers
performing
Optimization of operating cost and
DR owner may choose to purchase versus produce power based upon cost analysis
with key interfaces between
DR owner/operator and DisCo
with communication configuration
requirements of
WAN for communication from DisCo to
DR/Owner
with quality of service
requirements of
High availability
Medium volume
Frequent updates
with security requirements of
DA critical data requires very high
Breach of DA system can result in severe disruption
with data management requirements
of
Model maintenance will require update
of many legacy and non-legacy data
Real-time DA data will generally be stored in commercial data sources

L-11 Residential generation devices
The Purpose of
Residential generation devices function
is to Provide electrical power to residence while
remaining in parallel with ESP
directly involving
Residential DR owner/operator
ESP
performing
System operation to maximize asset
utilization
Routine maintenance activities
Control functions for meeting load demand
Monitoring operation of DR device
with key interfaces between
DR owner/operator and ESP
with communication configuration
requirements of
WAN for communication from ESP to
DR/Owner
with quality of service
requirements of
High availability, medium volume,
frequent
On/off control by ESP
with security requirements of
DA critical data requires very high
Breach of DA system can result in severe disruption
with data management requirements
of
Moderate – mainly associated with the
operation of the local system and associated data recording and transferring
functions
