DR Event Scheduler
DR Event Scheduler is a software package available in all GRIDlink products.
DR Event Scheduler works with or without a Demand Response Automation Server (VTN). It is not intended to replace an Open ADR Server but to add powerful Demand Response functionality in cases where the user wants to:
- Implement a pilot program for a small number of test units before an Open ADR Server vendor is selected.
- Automate an existing manual system.
- Use as a “Starter” or “Low Scale” DR program.
It may not be clear that the available load sheds can provide the requisite kW reduction without unforeseen ramifications. DR Event Scheduler offers the capability to fully test the concept. The user can schedule events, shed loads and record kW reduction from KYZ pulses or Modbus power meters. This will serve to justify the investment as the Utility scales up to an Open ADR Server.
There are a significant number of manual programs using telephone, pager, cell phone, email or fax for notification. DR Event Scheduler can automate the “Event Notification” process within the participant’s organization.
When customers are notified of an upcoming event, they need to implement an action plan or checklists previously developed in preparation for the event. DR Event Scheduler allows the dispatcher to schedule the event instantly. Notifications are sent out to staff via email or SMS texts. Loads can be shed manually or by using GRIDlink outputs using relays, Modbus or BACnet commands. The event is fully data logged and the load shed can be seen in real time via GRIDview. This saves time and eliminates human error which could result in higher rates .
The initial investment of an Open ADR Server can limit a Utility from creating a program particularly if there are a small number of potential participants. The DR Event Scheduler is a low cost solution that can be implemented in just a few weeks for 1 or more participants. It will provide full load shedding capability today without an Open ADR Server and be able to connect to a certified VTN (Virtual Top Node) at anytime in the future .
Option to implement Open ADR in the future.
GRIDlink ADR is a fully certified 2.0a/b Open ADR end node which can be connected to an Open ADR Server anytime in the future through our GRIDview cloud server.
How DR Event Scheduler works.
One or more GRIDlinks can be installed in typical participating locations or test sites. These can be connected to meters for real time load shed analysis.
- The dispatcher receives a notice of an Event for the next day or days.
- Logging on to our secure GRIDview site, the dispatcher enters the day, time and duration of the Event. Up to 5 Events can be scheduled at different times and days.
- An email or SMS text notification is immediately sent to predefined recipients. Further notifications are sent at each step in the Event until concluded.
- The Event is scheduled in the GRIDlink and will execute unless cancelled or “Opt Out” is selected.
- At the “PENDING” Notification time set by the dispatcher the first output is initiated prior to the start of the Event. This can energize a relay, send a Modbus or BACnet command which can begin a control logic such as pre-cooling or start a machine shutdown process.
- When the Event becomes “HIGH or MODERATE” and “Active” a second output is initiated to shed the loads. User can see the load shed on trend screens available in GRIDview in real time.
- When the duration period is complete, the outputs return to normal. Users can access the meter data and download to a csv file for further analysis.
