Newton Solution Convergence Parameters (V30.3)
Two new solution parameters in Version 30.3: Controlled bus Q mismatch convergence tolerance
(VCTOLQ = 0.1 MW/Mvar) Controlled bus voltage error convergence tolerance
(VCTOLV = 0.00001 pu)
Ensure voltage at controlled bus is being controlled if at least one of its
controlling devices is not at var limit.
Compatibility with convergence test in previous releases: Version 28 or earlier, set VCTOLQ = 1000, VCTOLV = TOLN/SBASE Version 29.0 through 29.5.1, set VCTOLQ=TOLN, VCTOLV =10 Version 30.0 through 30.2.2, set VCTOLQ=TOLN, VCTOLV=0.0001

Switched shunts which control voltage to a band can oscillate due to: Multiple devices electrically close to each other
Large admittance blocks Narrow voltage bands
New solution parameter SWVBND specifies the percentage (population) of
such switched shunts whose controlled voltage is outside of the desiredvoltage band which can be adjusted on any single adjustment cycle.
