Conservation voltage reduction based comprehensive power
In case of limited energy sources such as PVB, it becomes necessary to maintain continuity of supply. However, the adoption of conservation voltage reduction (CVR) in the distribution networks helps to reduce energy consumption [28–30]. In CVR, the supply voltage is reduced which in turn reduces the power (and energy) consumption.
