    Multi- Terminal UPFC for Power System Deregulation
    (IEEE, 2000-01) Mwinyiwiwa, Bakari M. M.; Lu, B.; Ooi, B. T.; Galiana, F. D.; McGillis, D.; Marceau, R.; Joos, G.
    One original purpose of FACTS controllers is to increase the transmission capacity of existing lines thus deferring the necessity of building new lines. FACTS, such as the unified power flow controller (UPFC), have also been regarded as controllers for routing power in the market-driven, deregulated power systems. Hitherto, the UPFC has been conceived to control the complex powers through a radial line. This paper presents the concept of a multi-terminal UPFC (M-UPFC), which serves to control the complex powers of several transmission lines converging towards (or radiating from) a transmission node. In order to show that a M-UPFC can be built, that it has stable operation and that it has all the control degrees of freedom of UPFCs, a laboratory model based on 3 units of 3-phase, voltage-source converters has been assembled and tested

    Multi-Terminal Unified Power Flow Controller
    (IEEE Transactions on Power Electronics, 2000) Mwinyiwiwa, Bakari M. M.; Lu, B.; Ooi, B. T.
    This paper describes a multiterminal unified power flow controller (M-UPFC) for the management of real and reactive powers of several transmission lines emanating from a single bus. The example of the paper consists of the bus of a generator station. The M-UPFC is based on synthesizing several of L. Gyugyi's UPFCs so that they share a single pair of DC buses. The realizability of the M-UPFC has been demonstrated experimentally in a laboratory-size model constructed from three insulated gate bipolar transistor (IGBT), voltage-source, sinusoidal pulse width modulation (SPWM) converters. An example is given where it is shown that the M-UPFC is more economical than single UPFCs Published in:
