I would suggest trying an Implicit Z-bus Gauss method, described
briefly in section 8.1.2 in my PhD dissertation http://www.pserc.cornell.edu/ray/pubs/PhDThesis.pdf

Due to low X/R ratio of the distribution network, the load flow
methods based on Gauss Siedel and Newton Raphson may not always
converges. For a radial system with only one voltage controlled bus
(which is the source substation), many simple algorithms exist in
literature which are not difficult to code.

As Dr. Zimmerman has said at least one generator is required at
slack bus to run load flow, one can assume the substation bus where
power is incoming as slack bus and place an equivelent generator at
that bus to run distribution load flow.
Best of Luck.

Sir,i m final year EE student doing project on capacitor placement
on radial distribution system. i m tying to run load flow on
matpower on default newton PF. I took data from Baran n wu
reconfiguration 32 us data ......there is problem while running the
load flow as data priscibe as in case9 is not same what i put for
32bus data....as what i take bus one as slake bus remaining PQ
bus .....the runpf is having error because there is no generator
data in what i enter there is only BUS AND LINE data....so please
sir help to this problem.
