Abstract
A voltage control device includes a voltage regulator module, a cooperative controller, and a conservation voltage reduction (CVR) factor calculator. The voltage regulator module regulates a voltage supplied to loads or reversely transmitted from the loads. The cooperative controller controls the voltage regulator module according to a target voltage or sending the target voltage to the voltage regulator module. The CVR factor calculator estimates a CVR factor. The target voltage is calculated by reflecting a voltage drop due to CVR using the CVR factor. The CVR factor is estimated in different methods according to at least one of a measurement time, a load state, and a representative value.
