“…The demand of lower power losses, faster response to system parameter change, and higher stability of system have stimulated the development of the Flexible AC Transmission systems (FACTS) [4]. Based on the success of research in power electronics switching devices and advanced control technology, FACTS has become the technology of choice in voltage control, reactive power flow control, transient and steady-state stabilisation that improves the operation and functionality of existing power transmission [5][6][7][8][9][10]. The potential benefits brought about by FACTS controllers include reduction of operation and transmission investment cost, increases system security and reliability, increased power transfer capabilities, and an overall enhancement of the quality of the electric energy delivered to customers [11][12][13][14].…”

The work entailed in this paper is to develop a model for the optimal location of shunt Flexible Alternating Current Transmission System (FACTS) along a transmission line so as to enhance controllability and increase power transfer capability of the transmission network. Mathematical models for maximum power transfer and transmission angles for transmission line were developed. The investigation was done for both lossless and actual transmission lines. MATLAB software was used for the simulation of the models. Aloaji-Itu transmission 132 KV transmission line in Southeastern Nigeria was used as a case study. Performance analysis was conducted on the various maximum power and transmission angles data for different degree of series compensation and FACTS locations along the transmission lines to determine the optimal location of the FACTS device for both lossless and actual transmission lines. The results obtained showed that the optimal location of the shunt FACTS device is not fixed, but changes with the change in degree of series compensation. Both the power transfer capability and stability of the system can be improved much more if the shunt FACTS device is placed at the new optimal location instead of the mid-point of the line.

“…At any instrument that is connected in series or parallel with the load and capable of supplying reactive power demanded by the load is called the reactive power compensation device. Reactive power is the component of power that oscillates back and forth through the lines, being exchanged between electric and magnetic fields [3]. In this paper, proposed a variable speed wind generation system based on (DFIG) with introduces the operation and control of a system.…”

Wind energy is a promising source of electricity in the world and fastest-growing. Doubly-Fed Induction Generator (DFIG) systems dominate and widely used in wind power system because of their advantages over other types of generators, such as working at different speeds and not needing continuous maintenance. In this paper used the PI controller and Flexible AC Transmission System (FACTS) device specifically static compensator (STATCOM) to investigate the effect of the controller and FACTS device on the system. PI controller tuning by Particle Swarm Optimization technique (PSO) to limit or reduced the fault current in (DFIG) system. The responses of different kinds of faults have been presented like; two lines to ground faults and three lines to ground faults at different operating conditions. Faults are applied to three proposed controllers; the first controller is the Proportional-Integral (PI), the second controller is PI-controller based on Particle Swarm Optimization (PI-PSO) technique and STATCOM. A reactive power static synchronous compensator (STATCOM) is used, the main aim for the use of STATCOM is to improve the stability of a wind turbine system in addition to this is improving voltages profile, reduce power losses, treatment of power flow in overloaded transmission lines. The simulation programming is implemented using MATLAB program.

“…In fact, these concepts and technologies are able to maintain major services to customers and power utilities either in normal situations or in blackouts scenarios and whereupon enhance the power quality, and improve the reliability of the distribution networks. Leading countries in SG investment and development (see the top ten countries for SGs investments in 2010 in the Table 1), has developed efficient action plans and strategic energy policies [8,9] to ensure the integration of an energy portfolio, that supports a smarter ecosystem which provides free and deregulated electricity markets [10], and a stronger economy, while other developing and emerging countries try to achieve SG planning within its economic and energy potentials [11].…”

Connecting Renewable Energy Sources and Systems (RESSs) to utility power grids is one of the most ambitious endeavors of Smart Grid (SG) development in many countries. The challenge of integrating RESSs is that it is highly variable, intermittent and unreliable. Electric power grids must therefore absorb this variability with a portfolio of solutions. Today, we are already seeing strong signs of convergence in the development of the power grid in many developing and emerging countries, and the transformation of the energy system through the efforts of different stakeholders in this field: academia as well as large and small businesses, who continue to push the boundaries of knowledge in the energy sector. On the other hand, governments need to come up with policies that promote innovation while not jeopardizing the SG infrastructure. This article has been arranged to introduce the subject in the first section, the second section presents the concept of a SG, then we involve in the third section a case study for Moroccan SG roadmap and the problem statement related to legislative context, which considered as a major obstacle for SG transitions not only in Morocco, but in some other developing countries. Hence, the last subsection proposes an efficient strategy as a solution to overcome some specific issues even in technology or in regulatory, while the forth section was devoted to the conclusion.
