Combined comparison-regression method for assessment of CVR effects

This paper introduces a combined comparison and regression method to quantify a credible estimation of the energy saving effect produced by Conservation Voltage Reduction (CVR). It is presented as a step by step tutorial on how to assess CVR effects with existing resources and tools at every control room in electrical distribution utilities. The method was tested in a distribution network in Canary Islands (Spain) resulting a CVR factor of 0.8211 and 9.42 MWh saved during one day operating with 2.97 % voltage reduction, equivalent to the consumption of 848 households in the region.
