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 ...
