SmartDR is a fully integrated, flexible and feature-rich Demand Response (DR) solution. It is designed to run on the SCADA host, with a user interface built into the WorldView operator interface. SmartDR is therefore fully redundant along with the rest of the SCADA system.
There are three applications that fall under the SmartDR product category:
- Advanced Metering Infrastructure (AMI) Interface
- Load Curtailment
- Dynamic Voltage Regulation (DVR)
Advanced Metering Infrastructure (AMI) Interface
AMI Interface allows the SCADA system to obtain meter data by interrogating the AMI system using the MultiSpeak protocol. The user can request readings from any meter and display the data on-demand in the WorldView map.
Users can also define schedules for the SCADA system to automatically interrogate the AMI system for specific meter data. The received data is stored in the analog points. This data can be used by other applications such as voltage readings for voltage reduction algorithms.
Load curtailment in Windows SCADA makes use of a high-level "supervisory" program to monitor conditions on your system and make decisions about when and how load shedding will be required. It then uses a low-level "executive" program to execute the desired strategies and perform the controls necessary to shed the desired load.
Dynamic Voltage Regulation (DVR)
Dynamic Voltage Regulation (DVR) is a reduction of energy consumption resulting from a reduction of feeder voltage. The objective of DVR is to have the customer’s voltage at the lowest level consistent with proper operation of equipment and within levels set by regulatory agencies and standards setting organizations. ANSI Standard C84.1 sets the range for voltages at the distribution transformer secondary terminals between 114 and 126 volts. The goal of DVR is peak demand avoidance from the reduction of feeder voltage, while maintaining ANSI Standard of 114 end of line voltage.
