“…Also, it is assumed that the loads on nodes 13,14,15,16,19,20,22,27,32, and 37 are random variables that follow normal distribution [34]. It is supposed that the expected values of these variables in various time intervals are equal to their values obtained from (28) and (29).…”

“…The main challenge in resolving the optimization is related to nonlinearity of the Power Flow relations (10), (11) and also to nonlinearity of the line thermal limits (17). Available nonlinear solvers, such as IPOPT, are not effective in resolving the nonlinearities for large systems efficiently.…”

“…However, it also became clear from the studies that this sustainable upgrade needs to be creative -types, locations and capacities of the newly introduced FACTS devices must be chosen carefully in order to exploit their benefits. Several objectives, including decreasing operational [7], [10], [11] and investment costs [5], [9], reducing transmission losses [6], [10], increasing power system loadability and managing system congestion [10], [12]- [14], reducing load curtailment [15] and improving voltage profile [9] and voltage stability index [8], [14], have been considered. Formally, these problems were stated as mixed Integer Nonlinear Programming (MINLP) optimizations which exact solutions are limited to only very small (typically not exceeding tens of nodes) power system models.…”

“…Some criteria have been proposed for the proper placement of FACTS devices in recent research. In such research, transmission capability, load flow equations, different points' voltages [7,15], voltage stabilities [13], transient stabilities and market optimization [3], consumer load variations, and variable amounts of renewable energy generation [14] are the most important factors considered in allocation of FACTS controllers. To achieve the optimum locations for FACTS devices, some evolutionary algorithms (e.g., genetic algorithm (GA), particle swarm optimization (PSO), and imperialistic competition algorithm (ICA)) have been used in different research projects.…”
