Resumen
The network reconfiguration for service restoration
(SR) in distribution systems is a combinatorial complex optimiza-tion problem since it involves multiple non-linear constraints and
objectives. For large networks, no exact algorithm has found
adequate SR plans in real-time. On the other hand, methods
combining Multi-objective Evolutionary Algorithms (MOEAs)
with the Node-depth encoding (NDE) have shown to be able to
efficiently generate adequate SR plans for large distribution sys-tems (with thousands of buses and switches). This paper presents
a new method that combining NDE with three MOEAs: (i) NSGA-II; (iii) SPEA 2; and (iii) a MOEA based on subpopulation
tables. The idea is to obtain a method that cannot-only obtain
adequate SR plans for large scale distribution systems, but can
also find plans for small or large networks with similar quality.
The proposed method, called MEA2N-STR, explores the space of
the objectives solutions better than the other MOEAs with NDE,
approximating better the Pareto-optimal front. This statement
has been demonstrated by several simulations with DSs ranging
from 632 to 1,277 switches.
