Influence of Flexible Alternating Current Transmission System on Transient Stability of Power Systems Using MATLAB CODE and Power World Simulator| Chapter 2 | Novel Research Aspects in Mathematical and Computer Science Vol. 6

 

 Using the Power World Simulator programme and the MATLAB-created transient stability code, or "TRANS STAB CODE," this work aims to explore how FACTS influences the transient stability of power systems. In the work's introduction, we tried to explain transient stability, including its definition, requirements, and equations. Next, we gave a comprehensive overview of FACTS modelling in power systems, including its definition as well as its many forms, schemes, and equations. Then, using the UPFC (Unified Power Flow Controller) concept, we gave an illustration. Second, we examined the "TRANS STAB CODE" MATLAB code by outlining its organisation using graphical windows. After then, I went into private detail about the simulation programme Power World Simulator. The test electrical network was then displayed, along with the Power World Simulator's findings on this network's transient stability and the code "TRANS STAB CODE" for both the presence and absence of flexible alternating current transmission networks. We evaluated the results of both programmes in both scenarios—with and without a flexible AC transmission system—as our final step in the research process.

An Innovative Fuzzy Rule Based Control Analysis of Advanced Unified Power Flow Controller | Chapter 9 | New Approaches in Engineering Research Vol. 1

 The rapid development of high power semiconductor devices with fast control features has enabled more efficient and effective power flow control. This category's Flexible AC Transmission Systems (FACTS) introduces several novel operating control devices. The Advanced Unified Power Flow Controller (AUPFC), also known as multi-converter UPFC or Generalized-UPFC, is a recent device that can control the bus voltage and power flows, both real and reactive, of multiple lines or even a sub-network. This chapter describes a novel real-time approach for analyzing the Advanced Unified Power Flow Controller. Based on the analysis, a new fuzzy logic rules-based controller that improves system performance has been proposed. The controller rules are built around the relationship between the series inserted voltages in multi-line and the desired changes in real/reactive power flows in the power system. The effects of various controllers, as well as the parameters of series transformers and transmission lines, were investigated using SIMULINK control block models. A case study demonstrates the effectiveness of the proposed scheme.

Study on Optimal Location of FACTS Devices by Evolutionary Programming Based OPF in Deregulated Power Systems | Chapter 8 | Theory and Practice of Mathematics and Computer Science Vol. 4

 In order to reduce transmission line congestion in the deregulated power system, this paper introduces an Evolutionary Programming (EP) approach to solving the optimal power flow with the Versatile Alternating Current Transmission (FACTS) unit. Protection and stability restrictions restrict the amount of electric power that can be transferred between two places through a transmission network. One of the technical problems, particularly in the deregulated setting, is congestion on the transmission lines. Private power producers are growing rapidly in the deregulated power industry in order to meet rising demand. The goal of the transmission network is to pool power plants and load centres in order to provide the load with the reliability, maximum efficiency and lower costs needed. When power transfer increases, with unscheduled power flows and greater losses, the power system becomes increasingly more difficult to operate and dangerous. The goal of FACTS devices is to regulate the flow of power so that it flows through the specified routes, to increase the capacity of the transmission line to its full thermal limit, and to improve the protection of the transmission system with minimal investment in infrastructure and environmental impact. An emerging FACTS system used in this paper to minimise congestion is the Thyristor Controlled Series (TCSC) capacitor. The suggested method introduces output index parameters to optimally locate TCSC for congestion relief. The goal function is nonlinear in congestion management. An EP-based approach is then used to solve the issue of Optimal Power Flow (OPF). It is considered that the IEEE 14 bus system demonstrates the suitability of this algorithm and the results are appreciably strong.

Perspectives of Truth and Lie in the Media: Analysis of Principles and Practices of Journalism Faced with the Postulate of Sacredness of Facts | Chapter 6 | Emerging Issues in Science and Technology Vol. 4

Journalism is an answer to a crucial intellectual need of humanity, the one of information. With respect to senders, information is an answer to the human need of self-affirmation and projection all over the world. With respect to receivers, it is a matter of tacit security need. In fact, the human being is in a permanent quest of knowledge (receiving information on) of what is happening around the people he is in relation with (knowing possible threats and the ways of avoidance). Despite its evident importance, journalism is all the same subject to criticism from all the members of the public. Criticism from all the members of the public appears all the more contradictory since it is postulated in it that “facts are sacred and comments are free.” The postulate of the sacredness of facts suggests that the processing of current events in this job could and should be done without distortion. The gap on the one hand between sacredness assigned to facts in journalism and on the other hand, the frequent call into question of journalistic discourse by its receivers is the main problem that this article proposes to solve. Our hypothesis postulates that facts cannot be looked as sacred in journalism because on the one hand, realities they depend on and on the other hand, professional practices and principles of journalism compel to their manipulation. From the methodological point of view, this hypothesis enables to follow the scientific approach, the technical know-how and the artistic expression of journalism in order to unseal in it the conditions of possibility of a sacralizing processing  (objective) of facts. This exercise enables the validation of our hypothesis. Such a conclusion leads to, not to validate journalistic discourses but rather to consider them in their essence that is as constructs aiming at making a precise imagination. In this context, there are no untruthful media, and even less truthful media, there are only media that produce specific imagination on reality considered through a fragmented and biased look they have at it. This posture releases all the members of the public from the trap of the Manichean and moralist perception of the media.
