Capacitor voltage regulation compensation
Comprehensive review and a novel technique on voltage unbalance compensation
A capacitive shunt compensation can support LVDN not only for voltage regulation but also for voltage unbalance compensation. Pană et al. [ 52 ] present an unbalanced capacitor compensation in a delta connection to mitigate the load unbalance as well as providing the reactive power compensation in a three-phase three-wire network.
