The demand for electricity is currently growing rapidly. In accordance with the government's policy to optimize the use of renewable energy sources, including water, by constructing a hydroelectric power plant. The study of the potential utilization of the Batang river flow is aimed at how much of the optimum electric power potential there is in the utilization of the Batang Merangin river flow as a hydropower plant. The results of the calculation of the potential for electric power at the Kerinci PLTA show that the optimum electrical power that can be generated is 366.27 MW and the energy produced annually is 1,443.86 GWh. The cash flow of the Kerinci hydropower project consists of technical estimates, revenues, operating and maintenance costs, inflation, taxes, and depreciation. Benefit-cost ratio analysis is calculated according to probable economic conditions during construction and lifetime. The initial investment cost for the Kerinci hydropower plant is around 12,922,000,000,000. The net present value obtained is 423,372,934,373, the internal rate of return is 10.7%, the return on equity is 16.2 years and the benefit-cost ratio is 1.2. The results show that the Kerinci hydropower plant can be built in terms of both technology and money.

ANFIS based AZSPWM methods for reduction common mode voltage in asynchronous motor drive R. Lingangouda; Pradeep B. Jyoti
International Journal of Applied Power Engineering (IJAPE) Vol 11, No 4: December 2022
Publisher : Institute of Advanced Engineering and Science

Space vector pulse width modulation (SVPWM) is a popular technique in the field of variable frequency induction motor drives. It gives better working and good direct current bus utilization in comparison to the sinusoidal PWM (SPWM) method. However, it decreases harmonic fluctuations and generates high common mode voltage (CMV) fluctuations, which results in common mode currents inside the motor. Hence, the performance of the motor may be deteriorated. To reduce the CMV, this paper presents a family of active zero state PWM (AZSPWM) methods using an adaptive neuro-fuzzy interference system (ANFIS). The proposed approach uses a five-layer hybrid learning algorithm for training the network. The training data is obtained from the classical SVPWM method. To analyze the proposed PWM methods, simulation is carried out using MATLAB and evaluated.

Publisher : Institute of Advanced Engineering and Science

Permanent magnet synchronous machines (PMSMs) are gaining popularity due to renewable energy and the electrification of transportation. Permanent magnet synchronous machines are receiving interest because to their great dependability, low maintenance costs, and high-power density. This research compares surface mounted permanent magnet (SMPM) with interior permanent magnet (IPM) synchronous machines using MATLAB. Mathematical models and simulation analyses of two permanent magnet synchronous machines under regenerative braking are presented. Maximum regeneration power point (MRPP) and torque (MRPP-torque) for two machine types were simulated at variable electrical speed and q-axis current. Simulation results showed IPMSM produced more output power due to saliency than SMPM at varying speed and current with higher MRPP and MRPP-Torque. Simulation was used to compare the dynamic impacts of constant and variable braking torques on an auto-electric drive's speed and produced torque on a plain surface and a sloppy driving plane. 81.68% and 74.95% braking efficiency were measured on level ground and a sloppy plane, respectively. Simulations indicated that lithium-ion battery state of charge varied linearly with constant braking torque and exponentially with varying braking torque, reflecting efficiency values. All simulations were in MATLAB/Simulink 2014.

Design and development of photovoltaic based grid interactive inverter G. Vijayakumar; M. Sujith; Dipesh B. Pardeshi; S. Saravanan

Publisher : Institute of Advanced Engineering and Science

In order to trail and produce the power generated on the photovoltaic (PV) array to the grid, a PV exhibit coordinated double lift DC-AC converter used as a contained single-stage micro inverter is introduced in this research. The flowing association of a DC converter, rectifier, and an inverter is used in the single-stage micro inverter to provide high supporting rise with a minimal obligation proportion. Due to the utilization of a greater variety of force-exchanging devices, the flowing association of the converters, however, gives limited change efficacy. With fewer switches and hidden components, the suggested disengaged double lift small inverter is intended to provide high power from maximum power point tracking (MPPT) proficiency, high transformation proportion, and high change effectiveness. The stoop reflections and the small inverter's six distinct techniques are presented. To support the display of the double lift DC-AC converter worked small inverter, the recreation and results of the exploratory proto sort are presented.

A brief review on hardware structure of AC electric spring Jyoti Rokde; Archana Thosar
International Journal of Applied Power Engineering (IJAPE) Vol 11, No 4: December 2022
Publisher : Institute of Advanced Engineering and Science

Decarbonizing power generation and reducing greenhouse gas emissions require renewable energy sources. Intermittent nature of renewable energy sources can cause blackouts, fluctuation in voltage, grid-connected inverter usage, inability to predict power generation, fluctuations in voltage and frequency. It is possible to balance between the supply and demand of power to overcome these problems by using an electric spring (ES). It is necessary to study its work, types, and controlling actions for realizing the benefits of the electric spring. This paper reviews the hardware structure of an ES based on voltage-source inverter (VSI) and current-source inverter (CSI) topologies, in single-phase and three-phase AC power distribution systems with renewable energy sources. The structure, control strategies, operating modes, advantages and disadvantages of each ES topology are elaborated to make it a suitable alternative for resolving different power quality issues caused due to the high penetration of renewable energy sources.

Power loss minimization assessment of a doubly fed induction generator with variable core resistance for wind turbines operation Crescent Onyebuchi Omeje; Damian Benneth Nnadi

Publisher : Institute of Advanced Engineering and Science

This paper assesses the efficiency level and power loss minimization of a doubly fed induction generator (DFIG). A modified DFIG equivalent circuit with multi-core resistance connected in parallel was adopted. State-space differential equations of the DFIG was developed incorporating iron and copper loss components while a minimum flux linkage that aids in the minimization of the overall losses was derived. Simulation results showed that losses were minimized when the equivalent core resistances were connected in parallel with minimum permissible current flow. The results obtained during a transient disturbance showed that at different core resistance values of Rfe = 0.75Ω and 0.25Ω, different efficiency values of 83.45% and 41.21% were realized. An unconstrained optimization test carried out on the DFIG variable parameters showed that the DFIG power loss model was controllable with a positive definite value of 691.9801 and 2.9156〖e〗^(+5) for the leading principal determinants of the Hessian matrix. All simulation processes were achieved in MATLAB/Simulink 2020.

International Journal of Applied Power Engineering (IJAPE) Vol 11, No 4: December 2022
Publisher : Institute of Advanced Engineering and Science

The work carried out in this article essentially relates to the application of a synergetic control to the piezoelectric positioning mechanism or piezoelectric actuator (PEA). A LuGre model has been followed, capturing the most physical phenomena, in order to be able to follow the most realistic and representative model possible. From this model, which is then identified by particle swarm optimization (PSO), we apply the synergetic control technique, which is a very efficient control method that allows demonstrating the good functioning of the stability of nonlinear system in closed loop. The simulation results have been compared to those obtained when using sliding mode to confer the best performance in terms of tracking error and minimization of oscillations.

International Journal of Applied Power Engineering (IJAPE) Vol 11, No 4: December 2022
Publisher : Institute of Advanced Engineering and Science

In the present work, using quantum-chemical calculations in the framework of density functional theory (DFT), we study the optical properties of semiconductor nanocrystals of kesterite Cu2ZnSnS4 doped with Se. Using the WIEN2k package, the concentration dependences of the optical characteristics of nanocrystals of the Cu2ZnSnSexS4-x system (x = 0, 1, 2, 3, 4) were calculated. It is shown that doping with Se at the S position leads to a noticeable improvement in the photo absorbing properties of these nanocrystals, as well as their photoconductivity in the IR range. The calculated absorption and extinction spectra of the materials under study, are compared with experimental data known from the literature. The data obtained will significantly enrich the existing knowledge about the materials under study and will help expand the scope of these compounds in optoelectronic devices, especially in solar cells and other devices that convert solar energy into electricity.

International Journal of Applied Power Engineering (IJAPE) Vol 11, No 4: December 2022
Publisher : Institute of Advanced Engineering and Science

With the ever-increasing load demand throughout the globe, natural renewable resources integrated into the existing network architecture for sustainable energy production are gaining considerable significance. Photovoltaic (PV) generation systems is one such technique to deal with the worldwide challenge for achieving green energy and low carbon footprint while simultaneously providing emission free electrical power from solar radiations. In this paper, we consider smart grid architecture connecting the end-users and the utility power plant with solar energy sources through an effective power optimization system. Multiple performance criteria associated with solar cell operation are evaluated and analyzed using the simulated annealing algorithm. These objectives considered for optimization include the cell saturation current, photo-generated current, material band gap, cell temperature, annualized life cycle cost, fill factor and cell efficiency. The formulated optimization conditions are specified in terms of two independent variables of cell ambient temperature and cell illumination. Moreover, the adaption of distinct values of short circuit current coefficients on the light originated current is measured. Through extensive simulation experiments, two disparate annealing procedures of fast annealing and Boltzmann annealing are applied coupled with three categories of temperature update schemes, viz. exponential, logarithmic and linear.
