Load management by voltage optimization: Experimental investigation of voltage variation effect on lighting loads

Load power demand management is important both for final users and for Distributed System Operators (DSOs) in order to manage their network load profile. So several strategies were adopted to get this result, but nowadays the new technologies in electrical loads as lighting systems are changing the electrical loads behaviour. Therefore, it is necessary to reconsider techniques of voltage optimization and their validation. The paper investigates voltage variation effects on several lighting loads. Effect of voltage variation on both Active and Reactive power consumption are taken into account and results are reported in the work.
