چكيده فارسي :
Changing the steady state parameters of power
system before fault occurrence is a new approach for increasing
the transient stability of the system. With the presence of PMUs
in smart grid and the possession of system information at any
given time, FACTS devices can be set up online so that total
critical clearing time (CCT) of the network is maximized as the
most accurate transient stability criterion, by changing the
system s steady state variables before the fault occurrence.
Calculation of CCT requires iterative fault analysis and timedomain
simulation of the network. In this paper, a novel prefault
online optimal FACTS tuning is presented for transient
stability enhancement of smart grid by CCT maximizing. Also
the optimal type, number and location of FACTS devices are
determined for long term planning. FACTS devices modeling
and New England 39-bus system simulation are done by
DIgSILENT software. DPL is used for CCT calculation and
proposed approach implementation based on PSO algorithm.
Also investment cost of these devices are considered for
determining the optimal number of them.
