PURPOSE ^

MAKE_VCORR Voltage Correction used in distribution power flow

SYNOPSIS ^

function V_corr = make_vcorr(DD,pv,nb,nl,f,Zb)

DESCRIPTION ^

MAKE_VCORR  Voltage Correction used in distribution power flow

   V_corr = make_vcorr(DD,pv,nb,nl,f,Zb)

   Calculates voltage corrections with current generators placed at PV
   buses. Their currents are calculated with the voltage difference at PV
   buses break points and loop impedances. The slack bus voltage is set to
   zero. Details can be seen in
   D. Rajicic, R. Ackovski and R. Taleski, "Voltage correction power flow,"
   IEEE Transactions on Power Delivery, vol. 9, no. 2, pp. 1056-1062, Apr 1994.
