Conservation voltage reduction: Estimating methodology for a large regional application

摘要

Conservation Voltage Reduction (CVR) is an established and cost-effective practice that has motivated many utilities to investigate its application on individual systems. This paper describes a supply-curve methodology that can determine the conservation value of CVR applied to many distribution systems in a region. In the area served by Bonneville Power Administration involving approximately 150 utilities, the systematic implementations of CVR could conserve between 170 and 268 Average Megawatts at a cost of 5 cents/kWh. This was shown to be a larger resource than might be achievable by applying more conventional efficiency improvements to transmission and distribution (T&D) systems in the region.
