double qCalc = q.eval();
double bSum = shuntCompensators.stream()
.mapToDouble(ShuntCompensator::getB)
.sum();

Be careful here because even if we have one or several shunts connected to a bus, the sum could be equal to zero. All b values can be equal to zero, or all b can be non zero value but with a sum equals to zero.

If we have access to the bus voltage in the LfShunt, we don't need q anymore. @geofjamg what do you think ?
