With the proliferation of renewables and energy storage, inverters and converters are being updated to outperform their antecedents in every possible aspect for numerous applications in fields and industries. The proposed research involves the design and implementation of improved three interface converter, and B4-Inverter fed brushless direct electric current motor drive for industrial uses. The proposed integrated Three Port Converter (ITPC) and B4-Inverter fed Brushless Direct Current Motor (BLDC) drive is proposed targeting low or medium applications. The ITPC has been operated in unidirectional and going in both directions for accomplishing a built-in dual electric potential and power rate of flow control. besides, efficiency and the losses of the proposed converter are analyzed using three different domains, i.e., battery charging, discharging, and photovoltaic (PV) effectively. The results are validated by performing simulations of the proposed systems in MATLAB/Simulink. The validation results reveal that the proposed converter works under all three domains and that the losses in the PV domain are reduced compared to the other converters. Also, the average efficiency achieved is 80.95%. These results authenticate the application of the proposed converter to numerous applications pertaining to renewable energy resources and energy systems.

In modern power system the economic load dispatch is considered as a non-linear problem. Many conventional and modern optimization algorithms are proposed to define a solution for the economic load dispatch. Among them, Teacher and learner based optimization is considered as one of the modern searching algorithms. This paper aims to solve the non-linear problem that exists in economic load dispatch using TLBO. Generally, the non-linear problem of economic load dispatch deals with the number of constraints inequality available in nature. The constraints are mainly the voltage, real and reactive power, shunt capacitor, transformer tapping etc. TLBO leverages on optimal solution to the nonlinear problem with a good convergence ratio.

The proposed research involves, a design and implementation of DC source fed improved Dual output Buck-Boost converter for agricultural and industrial applications. It consists of step up and step-down converter, DC-link module. Compared with conventional two converters, the designed system results in reduction of voltage tension across the switches, compact power switches, DC source reckoning and reduced inrush current. DC-link switching is achieved by reduced ripple voltage which results in improved quality of obtained output power. Reduction in switch count makes the system more cost effective. In addition, the motor speed is regulated by PI controller. Brushless DC Motor produce torque ripple and cause mechanical vibration, acoustic noise due to structural imperfectness and control system, to overcome this suppression control method of vibration for brushless DC motor utilizing feedforward compensation with Fourier transform utilizing a vibration signal acquired by an acceleration sensor attached to the motor frame is proposed. A simulation and prototype model of Dual output Buck-Boost converter is developed, and its performance is analysed for various operating conditions.

The Three Port Converter has been proposed and operated in unidirectional and/or bidirectional way simultaneously, for achieving an inherent dual voltage and power flow control. Switch count makes the system more cost effective. An excellent tracking performance under dynamic condition with negligible oscillations around optimum operating point is achieved. Optimally selecting the initial value of duty ratio and its perturbation size offer soft starting of BLDC motor by slowly increasing the DC-link voltage of VSI.

Proposed method selection depends on plant operating conditions and also depending upon the process dynamics. The PID controller is most widely used for industrial process control. Modeling were developed for modified internal control model [4-6] in this proposed research. The proposed work is the modeling and simulation of three different first order processes with dead time. The standard controller tuning method is used to obtain the steady state response of first order with dead time.

Energy is an essential commodity for everyone, with electrical energy being the most preferred form. Unfortunately, non-renewable energy resources are gradually depleting, and renewable energy sources take several years to establish. To mitigate this problem, technology has shifted from non-renewable energy sources to electrical devices and machines, including household appliances like washing machines and air conditioners. However, the generation of electricity is still inadequate to meet the growing demand. This leads to two critical issues: Excessive power loss and inadequate voltage stability, making it difficult for power distribution companies to ensure a consistent and reliable power supply. The objective of this study is to tackle the issue of reduction and minimization of power dissipation By employing the PSO technique, adjusting the transformer tap settings. The proposed approach uses the 14-bus system as a reference and calculates losses for this system using the backward-forward sweeping technique.
