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 (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.

The paper describes a cooperative hypermedia approach to developing a toolkir for team building activities that oflen occur in research group meetings or organisation may day events. Each tool is developed and applied using a well-known PowerPoin:metaphor. The novelty of the work is reflected on its jlexibie coordination and facilitation support, its seamless connection between tools for each phase of a team building activiiy, and its support for follow-up actionr. The requirements for the above mentioned feutures are derived from an anabsis of existing practice. Two examples are given to show how typical team building exercises can be supported using the hyper-media based groupware tools.
