This paper describes an implementation of Tabu Search to cope with long-ter
m transmission network expansion planning problems. Tabu Search is a metahe
uristic proposed in 1989 to be applied to combinatorial problems. To assess
the potential of our approach we will test it with two cases of transmissi
on network expansion planning. The results obtained by our approach let us
to conclude that TS is a robust and promising technique to be applied in th
is problem.
