In this paper we employ the Permanent Magnet Synchronous Generator (PMSG) for standalone wind power generation because it offers high efficiency combined with minimal maintenance requirements. A direct matrix converter based on smart technology functions as the power conversion interface to create output waveforms that are sinusoidal with limited higher order harmonics while having no subharmonic components. The system removes the requirement for dc-link and all other passive equipment. By using certain switching states Space vector modulation controlled (SVM) matrix converter switching has the potential to minimize switching losses. The proposed work stands as a potential design concept for future variable speed drive technology. The suggested model for an RL load underwent evaluation through MATLAB simulation by changing the resistor and inductance values.

A voltage-source inverter exists for one primary purpose. It performs voltage step-down operations. When voltage-type Z-source inverter first appeared, researchers added boosting capabilities while keeping the steady number of semiconductors constant. The new inverter generation demonstrates improved resistance to electromagnetic noise disturbances. The spectrum performance along with boosting ability suffers due to component stresses which causes poor performance at low modulation index ratios. Actual implementation shows their boosting capabilities remain restricted. The performance review of the generalized switched-inductor Z source inverter using PWM and SPWM techniques confirmed additional boosting capabilities and other benefits during simulation analysis and experimental testing enabling their adoption to overcome these constraints.

This work evaluates the brushless DC motor (BLDC) speed control when operated by traditional two-, three-, and five-level diode clamped multilevel inverters. A speed controller based on fuzzy logic (FL) operates to evaluate drive system performance effectively. The mechanism of controlling the proposed drive system receives further detail. The speed and torque performance of the usual two-level inverter gets evaluated against MLI configurations including three- and five-level operation for a diversity of working conditions. The mathematical model of a BLDC motor was built in the MATLAB/SIMULINK environment using IGBTs designed to simulate three and five level diode clamped multilevel inverters. The simulation data demonstrates that speed responses are swift and discontinuities in torque do not occur with the fuzzy-based speed controller. The developed fuzzy logic model demonstrates the ability to learn and change its control parameters autonomously while maintaining minimum steady state error, overshoot, and output voltage rise time across all disturbances.

In an ac transmission line, it is possible to control the active and reactive power transfer independently, by adding series compensation voltage, in both magnitude and phase angle, to the line. A transmission line is connected in series to the Static Synchronous Series Compensator and a solid-state voltage source inverter with associated transformer. In line series, a SSSC imposes a variable amplitude nearly sinusoidal voltage. This injected voltage creates seriatim inductive or capacitive reactance with the line as it is approximately 90° from the line current. The modulated reactance produces this (simulated) varying reactance which modulates the electric power carried through the transmission line. This focus on preliminary research for controller design motivated this study to attempt further development of the SSSC and VSC models.

To be able to predict power system grid fault conditions as such this study recommends an algorithm for smart home energy systems. The smart system that will regulate the electrical supply conditions to the load on the residential electrical system is a single-phase photovoltaic grid connected to a smart household energy system. Smart system consists of two voltage sources: photovoltaic as a backup supply and conventional power from the national electricity provider as the desirable source. Smart systems can predict faults being imposed on the load by controlling the proper voltage sources to feed it. Through detecting and identifying the voltage source’s amplitude, phase angle, and frequency with reference to system reference, the state of smart system can be described in terms of power flow control to the load. The system operates by utilizing a static transfer switch having a phase-locked loop to determine source of voltage. The outcome from the voltage detection algorithm is used to ascertain the decision logic algorithm for switching conditions. The results show that, if a fault condition occurs, the voltage source selection in the decision logic can be utilized to determine the circumstances of the smart power system flow.
