Abstract
Accurate power flow in a MT system can be achieved
with droop controllers. However, almost all publications have
assumed that the DC voltage, DC current and DC cable
resistances can be measured with 100% accuracy. In this paper, a
novel power flow solver is developed which enables the user to
analyse the impact of these parameters on power flow accuracy.
The developed Parameter Uncertainty Power Flow Solver (PUPFS)
is shown to be able to accurately calculate the power flow
error for hundreds of parameter uncertainty scenarios in less
than a second. The PU-PFS is employed to investigate the impact
of parameter uncertainty on a potential MT system and the
results show that realistic measurement errors (0.2%) can result
in significant power flow error (>150MW). Finally, the paper
assesses the key factors which influence the power flow accuracy
resulting in a number of important conclusions.
