Direct power control (DPC) has received a significant amount of research attention because of its benefits such as simplicity, robustness and excellent dynamic response. Conventional switching-table-based single-vector DPC (SV-DPC) presents irregular power ripples and variable switching frequency, due to the use of predefined switching table and hysteresis comparators. To solve these problems, two-vector DPC (TV-DPC) and three-vector DPC (THV-DPC) based three-phase pulse width modulation (PWM) rectifier are proposed. Although the performance of the THV-DPC is better than that of TV-DPC, its algorithm implementation is very complex and time consuming. In this paper, two-three combined vector DPC (TTCV-DPC) algorithm is presented which combines two and three voltage vectors by the help of the new switching table. The proposed algorithm has less complexity than the THV-DPC and better performance than the TV-DPC. Comprehensive simulations demonstrate the proposed method can get lower power ripple and lower grid-side current total harmonic distortion (THD) than that of TV-DPC.

The performance of induction generator (IG) based wind farms is not satisfactory these days. The existing IG based farms create a huge problem especially in case of expanding the capacity of the wind farm. This paper introduces a new solution for the problem. It suggests that the introduction of permanent magnet synchronous generator (PMSG) with IG, not only expands the capacity of the wind farm, but also it produces a stable output. A practical case considering Synchronous Generator (SG) in combination with a wind farm having both IG and PMSG has been used. The proposed PMSG has been equipped with the full-rated power converters. The results prove the effectiveness of the proposed model. Simulations have been done by using the engineering software PSCAD/EMTDC. Real wind speed data have been considered for this study.

A vehicle tracking system is very useful for tracking the movement of a vehicle from any location at any time. In this work, real time Google map and Arduino based vehicle tracking system is implemented with Global Positioning System (GPS) and Global system for mobile communication (GSM) technology. GPS module provides geographic coordinates at regular time intervals. Then the GSM module transmits the location of vehicle to cell phone of owner/user in terms of latitude and longitude. At the same time, location is displayed on LCD. Finally, Google map displays the location and name of the place on cell phone. Thus, owner/user will be able to continuously monitor a moving vehicle using the cell phone. In order to show the feasibility and effectiveness of the system, this work presents experimental result of the vehicle tracking system. The proposed system is user friendly and ensures safety and surveillance at low maintenance cost.

The aim of this paper is to analyze the effect of adding graphene layer on the porous silicon waveguide sensor. From rigorous theoretical calculations it is found that the resonant porous silicon sensor shows a 60-fold improvement in sensitivity over conventional SPR technology [1]. This paper proposes a Psi waveguide sensor designed in FDTD Lumerical software[2] with graphene layer. Due to having extraordinary properties, the added graphene layer increases the sensitivity of the sensor. This designed Psi waveguide sensor can be used as DNA detector[1], Optical gas sensor[3], Novel liquid sensor[4], Vapour sensor[5] with better sensitivity.

Dye-Sensitized solar cell (DSSC) has long been regarded as one auspicious choice for the alternative way to convert the solar energy to electric energy. In this work, DSSC has been fabricated using the natural dye extracted from Syzygium cumini fruits. Here, nanocrystalline TiO2 deposited on the fluorine doped tin-oxide (FTO) glass substrate has been used as dye absorber due to their high surface area and it shows high electron mobility, and carbon counter electrode has been used as a back electrode. The performance parameters of the solar cell have been achieved under AM 1.5 illumination. Optical and surface morphological studies of TiO2 film have been observed. The solar cell efficiency of 0.161%, short circuit current density of 0.952 mA/cm2, open circuit voltage of 735 mV and fill factor of 0.230 have been achieved in this study.

This paper presents analysis of a three phase hybrid multilevel inverter (MLI) by applying low frequency stair case control strategy. The proposed MLI contains three cascaded stages, auxiliary stage-1, auxiliary stage-2, and main stage. The main stage contains three half-bridge cells which are connected in parallel with a common DC power supply. Each of the stages in the auxiliary stages consists of three H-bridge where the H-bridge cells contain isolated DC power supplies. The proposed hybrid MLI is tested for symmetric and asymmetric configurations of input voltage sources of the main and auxiliary stages. A scaled down prototype of the proposed hybrid three-phase hybrid MLI is developed to verify the control concept and the real time performance of the inverter.

This research paper introduces the advantage of using graphene as a sensitivity enhancing material for the Surface Plasmon Resonance (SPR) Biosensor. Fresnel's four layer model has been used here for analyzing the performance parameters of SPR biosensor. The analysis shows that Surface Plasmon Resonance Frequency (SPRF) increases with the increasing concentration of target molecule for every graphene layer. It is found that the sensitivity curve for different graphene layer with respect to conventional SPR biosensor is non-linear. How the sensitivity increases with increasing graphene layer was studied in this work. The basic polynomial fitting is used and found that sensitivity increases nonlinearly with the increasing layers and the degree of nonlinearity also increases.

This paper presents a smart charge controller (SCC) that can extract maximum power from solar panel and could make instant decision to protect the system. In the same time the designed controller can control high voltage disconnect (HVD)-reconnect, and low voltage disconnect (LVD)-reconnect. An improved maximum power point tracking (MPPT) is achieved through a Peripheral interface controller (PIC) based Perturb and Observe (P&O) algorithm. Additionally, light emitting diode (LED) used as indicator and a display is featured to show the system status. A blue-tooth device is used to work it as a data logger to monitor system status by smart phone or Laptop. Furthermore, this SCC is developed to increase the efficiency with low cost. Experimented highest efficiency 99% is recorded within the cost of BDT 2050 taka only.

This article investigates the impact of cyber-attack on a power station in frequency disturbing aspects during sudden changes of load of the system and proposes a solution method to make it stable. Stable limit of the speed regulation for load frequency control (LFC) and integral controller gain for automatic generation control (AGC) is derived from their characteristic equations. Depending upon the nature of cyber-attack (positive biased or negative biased attack) simulations are performed to show the frequency deviations and oscillations of the power system. Finally a feedback LFC block with a three input switch is designed to remove these oscillations.

Thin-film solar cells (TFSCs) have the potential to reach cost effective photovoltaic generated electricity. Cadmium Sulfide (CdS) and Indium Sulfide (In2S3) buffer layer based Copper Indium Gallium Selenide (CIGS) solar cell offers higher efficiency with low manufacturing cost. Therefore, this paper presents a comparative study between CdS and In2S3 buffer layer based CIGS solar cell. The numerical study has been performed using a Solar Cell Capacitance Simulator named SCAPS-1D. The performance of CIGS solar cell is observed by adjusting the buffer layer thickness of both CdS and In2S3. The efficiency of CdS/CIGS solar cell is found 25.56% that is higher than the efficiency of In2S3/CIGS (24.41%) solar cell for 50 nm buffer layer thickness. It is also found that, the increase in buffer layer thickness from the optimum level degrades the performance of CdS/CIGS solar cell as compared to In2S3/CIGS solar cell. Therefore, In2S3 based CIGS cell could be an ideal candidate as a substitute of toxic CdS buffer layer based CIGS solar cell.
