More than one hundred countries are using wind energy due to their easy implementation, cheap energy, and high energy efficiency. Implementation of FACTS devices in Wind Energy Conversion Systems (WECS) has been dramatically improved due to cooperative and accurate performance of FACTS devices. However, dealing with wind turbine faults promptly is crucial. Short-term and long-term faults may ha...

This paper discusses the use of Genetic Algorithm (GA), Differential Evolution (DE) and Particle Swarm Optimization (PSO) based approach for the allocation & coordinated operation of multiple Flexible AC Transmission System (FACTS) devices for the economic operation as well as to increase power transfer capacity of an interconnected power system under different loading conditions. These Evoluti...

in emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. the flexible ac transmission system (facts) controllers can play an important role in the power system security enhancement. however, due to high capital investment, it is necessary to locate these controllers optimally in the power system. facts...

In electric power systems, finding optimal location and setting of flexible AC transmission system (FACTS) devices represents a difficult optimisation problem. This is due to its discrete, multi-objective, multimodal and constrained nature. Finding near-global solutions in such a problem is very demanding. Brainstorm optimisation algorithm (BSOA) is a novel promising heuristic optimisation algo...

This paper presents the effects of instrument transformers connection points on the measured impedance by distance relays in the presence of Flexible Alternating Current Transmission System (FACTS) devices with series connected branch. Distance relay tripping characteristic itself depends on the power system structural conditions, pre-fault operational conditions, and especially the ground ...

In this paper, a novel method using Bees Algorithm is proposed to determine the optimal allocation of FACTS devices for maximizing the Available Transfer Capability (ATC) of power transactions between source and sink areas in the deregulated power system. The optimizations are made on three parameters: the location of the devices, their types and their sizes. The FACTS devices are located in or...

Flexible Alternating Current Transmission Systems (FACTS) devices have been used for several targets in power system, one of the main contributions of the devices is improving operation conditions. In this paper, two types of these devices have been placed to raise voltage profile, minimizing system loss and arising loadability. The suggested FACTS devices are: Unified Power Flow Controller (UP...
