Optimum Reactive Power Dispatch for Alleviation of Voltage Deviations
Abstract: 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 generators excitation. The proposed algorithm for
voltage control uses a non-linear least square minimization technique. Results
obtained for 6-Bus Ward-Hale system and a modified IEEE 30-Bus system are
presented for illustration purposes.
