Analysis of Power Quality Problems on Nigerian 330 KV Power System Using Statcom with Voltage Sensitivity Index | Chapter 2 | Theory and Applications of Engineering Research Vol. 1

 In this study the cohesion of Nigerian transmission scheme during possibility (sag) was determined and appropriate placement of Static Synchronous Compensator (STATCOM) in method load buses where sag strength occur was accomplished as to defeat the Power Quality (PQ) problems emerging from habit of non-linear loads from the users which have negative impacts on the movement of the power arrangement. Thus, this research analyzed the PQ question on Nigerian 330 kV, 28-bus system. The Newton-Raphson (NR) repetitive approach was utilized to act load flow analysis on Nigerian 28-transport transmission methods. The STATCOM power dose model was then used to modify the NR numerical model. The optimal installation of the STATCOM in the system was raise using the Voltage Sensitivity Index (VSI), and imitation was performed in MATLAB/SIMULINK. According to the findings, highest in rank locations for the STATCOM boss in the power whole were buses 5, 8, 12, and 16.  The corresponding STATCOM sensitive power, sag power and sag duration for buses 5, 8, 12 and 16 were 72.56 MVar, 0.77454 p.u, 0.7336s; 65.35 Mvar, 0.7464 p.u,  0.7419 s; 50.86 Mvar, 0.7615 p.u, 0.6512 s and  53.75 MVar, 0.7442 p.u. 0.5972 s, respectively. As a result, the verdicts have demonstrated the meaning of STATCOM with VSI in judgment appropriate solutions for PQ issues in energetic power systems.

A New SVM Method for Improvement of Power Quality in Multilevel Inverter| Chapter 3 | Recent Progress in Science and Technology Vol. 4

 Some science with several guidelines has been grown to address the problems like voltage dip, sag, and ballooned. These advanced methods mitigate undesirable feature issues. Precise monitoring is finished by utilising proper power photoelectric devices.So much research work is continuing to give more focus to the microgrid network It has been intentional from the literature that harmonious distortion and voltage stabilisation are the bigger cause of power characteristic issues which may result by way of the evolution of nonlinear ploys.The power quality issues maybe resolved by utilizing different types of controllers like SVC, STATCOM, and filters. As the power is create and power devoured or controlled through a power photoelectric interface, the depository system takes a vital duty in its movement. It will continuously supply all types of loads for all types of situations. Inverters are executed for power transfer from the DC beginning (Photo Voltaic) to the AC bus. This introduces harmonious to the system. Therefore, it is very owned by analyse the control strategy of PV-based inverters. This presents the SVPWM method as the best possible method for harmonic reasoning. Several existing power status improvement methods and their merits and demerits have highly been present place each technique has a distinguishing area of application. Only the rhythm width timbre (PWM) technique has a broad area of custom, which contain space vector timbre (SVM). advanced treasure of PWM (Dodecagonal SVM) so on to mitigate the taller and lower order harmonics. They are technically pretty natural, possess high awareness, are inherently discriminating, immune to filter harmonious and external mistakes inherently selective, insensitive filter harmonious and external faults. This presents the SVM method as the best attainable technique for the mitigation of musical accordance, which made one of the stimuli for the research work.

Coordination of PSS and Facts Devices for Power System Stability Enhancement: A Comprehensive Review | Chapter 3 | Advanced Aspects of Engineering Research Vol. 8

 Power system stability has been and will continue to be a key challenge in power system operations due to power system oscillations caused by complicated interconnections.

Efforts have been made to dampen power system oscillations in order to improve power system stability. The instability caused by complex linkages is known as small signal stability. With power system stabilisers, small signal stability can be reduced (PSS). PSS, on the other hand, has several drawbacks, such as substantial voltage profile changes and the potential for leading power factor operations, both of which can degrade system stability in the face of severe disturbances. Traditional PSS may not be enough to attenuate inter-area oscillations and the influence of voltage profile fluctuation in large multi-machine power systems. Flexible Alternating Current Transmission System (FACTS) power electronic systems, on the other hand, are good at dampening inter-area oscillations and can tolerate voltage changes. As a result, this research provides a complete analysis and assessment of PSS and FACTS power oscillation damping (POD) controllers in minimising low frequency oscillations using computational intelligence methodologies. It is emphasised the necessity of technical paper publishing on PSS and FACTS-based controller design, optimum location, and parameter tuning. Finally, some future research directions for innovative PSS and FACTS devices are suggested as a resource for researchers.
