摘要: A method of determining one or more direct voltage reduction (DVR) factors at a point of load (POL) in a power grid voltage environment. An energy processing unit (EPU) is installed at each individual POL; each EPU includes at least one AC-AC series voltage regulator. An EPU-regulated output voltage is increased under specific controlled conditions. One or more independent DVR factors for each individual POL are determined during the increased and decreased EPU-regulated output voltage.
