Survalent Technology has released a new SmartDA application for controlling distribution feeder voltages: Dynamic Voltage Regulation (DVR). This DVR application encompasses the conventional Conservation Voltage Reduction (CVR) objective, provides capabilities for peak demand reduction and management of optimal feeder voltage limits.
"When we first started working on this application we were focused on Conservation Voltage Reduction (CVR)," states Young Ngo, VP Business Development. "The objective of CVR is to have the customer's voltage at the lowest level consistent with proper operation of equipment. Several studies have shown a 1% reduction in voltage equates to a 0.8 to 1% reduction in demand. We quickly realized that many of our customers had other objectives for controlling feeder voltages that did not fit the standard definition of CVR, such as peak reduction and optimal voltage limit. Dynamically controlling feeder voltage levels for peak reduction, or increasing voltage levels during peak load times have nothing to do with either conservation or reduction. A more appropriate term for this application is Dynamic Voltage Regulation (DVR).
Voltage regulation is a method of reducing energy losses and managing demand that has been studied and implemented by some utilities for over twenty years. These studies have concluded there is a relationship between voltage and load such that small deviations in voltage result in small changes in the load. If the feeder line voltage is lowered, the load will be reduced as a result. Voltage regulation leverages this dynamic relationship and the objective is to reduce the feeder or system voltage to the lowest point while managing the customers’ voltages within ANSI standards. The result is a reduction in load and a corresponding reduction in losses. When DVR is properly implemented, the reduction in voltage does not impact the quality of power or services on the end user. In fact, the customers will use less energy during the DVR operating period and their costs for electricity will be reduced.
DVR’s most noteworthy benefit is the demand reduction during peak periods where the cost of power to the utility is greatest due to the higher cost to run peaking power plants to meet the demand. It has been demonstrated by a number of utilities’ studies that for every 1% reduction in voltage the corresponding reduction in demand varies between 0.6% and 1.4%. The range of variance is dependent on the type of load or mix of loads of the feeder or distribution system.
Survalent DVR application effectively utilizes the SmartSCADA easy to use tools and system interfaces for utilities to set up and operate voltage regulation and achieve its business objectives. There are available interfaces to AMI data head end system for accessing and managing end of line voltage readings and standard protocols used to connect with voltage regulators and transformer load tap changers.
