Multi-Objective Optimal Placement of FCL in IEEE RTS 24 Bus System: a
Case Study Review
By increasing load demands and extending power networks to response
customers need the complexity and integration of power systems have been
boosted which increases the short circuit current level of the system
that may be a threaten for network’s reliability. Over these years, some
approaches have been proposed to deal with this issue, reconfiguration
of networks, increasing circuit breakers (CBs) capacity, and
implementation of fault current limiter (FCL) is as proper examples.
Reconfiguration and increasing CBs rating have applied exorbitant costs
to the system and in some cases, it may be infeasible. Hence, FCLs can
play a pivotal role in the mitigation of fault current level, but the
effectiveness of FCLs is depended to the numbers and impedance of FCLs.
In this paper, a novel and multi-objective approach are presented to
optimize three objective functions including decreasing short circuit
level, increasing the systems reliability level, and minimizing costs of
FCL installations. Adaptive penalty factor and Pareto based Multi
objective Evolutionary Algorithm Based on Decomposition (MOEA/D) is used
to optimize the aforementioned objectives. Numerical and graphical
results of optimization studies in MATLAB software on IEEE RTS 24-Bus
system are confirmed the proposed approach efficiency.
