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 (PU-PFS) 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.
