Optimum Reactive Power Dispatch for Alleviation of Voltage Deviations
TELKOMNIKA (Telecommunication, Computing, Electronics and Control), 2012 This paper presents a non-linear optimization algorithm for alleviation of under-voltage and over-voltage conditions in the day-to-day operation of power networks. Voltage control for varying load and generation conditions can be achieved by coordinated control of switchable shunt VAR compensating (SVC) devices, on load transformer taps (OLTC) and ...

Investigation of Phase-wise Voltage Regulator Control Logics for Compensating Voltage Deviations in an Experimental Low-voltage Network [PDF]
Electric Power Components and Systems, 2016 AbstractThis article investigates the control logics of an on-load tap-changer transformer by means of experimental system validation. The experimental low-voltage unbalanced system consists of a decoupled single-phase on-load tap-changer transformer, a 75-m 16-mm2 cable, a controllable single-phase resistive load, and an electric vehicle that has the ...
