The Effects of Reduced Voltages on the Efficiency of Electric Loads

Discussion

“…Other papers have examined the same questions by the same method (1,2,3): tests of actual system distribution circuits. Another type of approach, which seeks to provide fundamental data on the components of distribution circuit loads in the Laboratory Test, which applies controlled voltages to the individual devices commonly found on distribution circuits and records the performance of those devices; an example is the Electric Power Research Institute Report (4), which appeared in summary form as an Institute paper (5). A third way of approaching the topic is the development of equations representing the devices of interest (Analytic Methods or Model Development); an example is (6).…”

Application of autonomous smart inverter Volt-VAR function for voltage reduction energy savings and power quality in electric distribution systems

“…Conservation voltage reduction (CVR) is a methodology of lowering voltage on a circuit in order to reduce energy consumption [1], [2]. Traditional CVR employs local device settings to control load tap changers (LTCs), voltage regulators, and shunt capacitors.…”

Combined comparison-regression method for assessment of CVR effects

“…The power demand of certain loads changes with voltage [1]. This is the working principle of Conservation Voltage Reduction (CVR), a well known mode of operation to reduce energy consumption and peak demand.…”

“…This method is heavily dependent on the accuracy of the regression model. − Synthesis: From load components (appliances loads are modeled as function of voltage through laboratory tests and load contributions of each appliance are obtained through surveys) or from customer classes (residential, commercial and industrial which have different percentages of appliance load composition) [1], [11]. This method gives an early estimation of CVR effects before its implementation.…”
