A Practical Investigation on Conservation Voltage Reduction for its Efficiency with Electric Home Appliances

Conservation voltage reduction (CVR) method is a cost efficient solution to reduce the peak demand and power consumption. This method decreases power consumption of electric load by reducing the supply voltage. This method can be used within consumer premises to obtain more efficiency. But CVR cannot be commonly applied for all the electric home appliances. For constant power load CVR method is not suitable. So to test the efficiency of CVR under different electric home appliances, an experiment is done with commonly used electric home appliances. This experiment is done to compare and evaluate the efficiency of CVR the load power consumption values between appliances with CVR and without CVR. The results shows that majority of the home appliances reducing the power consumption with CVR method. Very few appliances tend to increases the power loss after applying CVR method. The detailed result is given in this paper. This results is used to modify the implementation process of CVR method to improve the efficiency. Results concluded that the CVR can be used for reduce the peak demand within consumer side with maintaining consumer comfort level. A new low cost smart plug design is given in this paper for implementing CVR within the consumer side.
