In this work, the different transition metals doped zinc oxide (ZnO) on aluminium (Al) film coated on glass substrate (i.e., ZnO/ Ai)were fabricated for device purposes. Initially, Al thin film on glass substrates was prepared by thermal evaporation technique by taking high purity aluminium metal. To get the desired growth of film, the prepared samples have been doped with the un-doped & Co-doped solution with the help of a modified version of dip-coating that is, chemically wet & dry (CWD) technique which can simultaneously & indeed control the immersion, uplift speed, drying inside and as well as the thermal annealing. The prepared samples were carried out by the X-Ray Diffraction (XRD) analysis for confirmation for crystallization. All samples are polycrystalline nature of Codoped and un-doped ZnO/AI were indicated by the XRD analysis. There were some shifting of peaks obtained in comparison to the reported data which implies that some percentages of Co diffuse into the ZnO matrix as both are similar size. The taken samples show the Ohmic contact nature as it is characterized by current-voltage (I- V) study. This Ohmic nature behaviour of contact between ZnO and Al at interface, can be used in sensing applications at low potential value. This prepared sample can be used as a very good low-cost electrochemical sensing material.

The sensor nodes in a Wireless Sensor Network (WSN) usually perform their assigned jobs with the help of a limited power supply (i.e. battery power). The lifetime of a sensor node is directly proportional to battery power. It is required to restrict the unnecessary consumption of power which is mostly associated with the transmission of a signal. In this paper, we compute the minimum power required to make a successful data transmission (referred to as optimum transmission power) so that the BER (Bit Error Rate) concerning the received signal at the destination node must satisfy the threshold level. Further, to improve the SNR (Signal to Noise Ratio) we consider the most commonly used MRC (Maximal Ratio Combiner) diversity based receiving system as a part of node architecture. To characterize the multipath fading scenario the generalized Nakagami channel is used for deriving the required mathematical expressions.

This paper presents an intelligent approach based on the fuzzy logic concept, to optimally find out the maximum power point (MPP) to extract maximum power from a photovoltaic (PV) array. The fuzzy logic-based MPP tracking (MPPT) is tested and analyzed through MATLAB/Simulink and hardware-based PV modules. To justify the feasibility of realtime application of the approach, a hardware setup is built using Arduino mega 2560 embedded board, MinGW-w64 simulator, and Simulink support package for Arduino Hardware in MATLAB/Simulink 2020. To execute the real-time conditions, both the temperature (T) and irradiance (G) variations are considered in different test cases. The results indicate the high efficacy and feasibility of the approach for real-time application.

Microgrid is the distribution grid that consists of local loads and load generation. Faults are the abnormal phenomenon that occurs in the Microgrid. Most CERTS Microgrid Test Bed consists of a well-equipped protection system. These Protection Schemes need an accurate, reliable and fast algorithm to detect the faults. Fast detection of faults protects grid and surroundings from damage. In this Paper Tunable Q-Wavelet Transform based entropy measurement algorithm is proposed to detect and classify the faults occur in CERTS Microgrid test bed. It is also tested on real time CERTS Microgrid based “Santa Rita Jail Microgrid” for validating the proposed algorithm. All the Simulation work are carried out in MATLAB/Simulink.

Electrical energy is an essential and integral part of human life. The use of electrical energy is increasing day by day and therefore it is important to plan a future power system well in advance to meet the expected demand growth with a reasonable reliability level at minimum cost. Nowadays, renewable power generation plays an important role in power generation since, it is pollution free and zero fuel cost. In this paper an effort is made to project a future power system for Assam, an Indian state. In the present power systems, the electricity is generated mainly from non-renewable energy sources which increase greenhouse gases (GHG) emission and hence global warming. Keeping in mind about pollution impacts, renewable energy sources like wind, solar, biomass for the planning a future power system of Assam using long range energy alternative planning system (LEAP) software is considered. The proposed capacity expansion is planned for next twelve years from 2019 to 2030. In this work, the various scenarios developed separately with LEAP are Greenhouse gas mitigation scenario, Low demand growth and High demand growth scenarios. In addition to these, reference scenario has also been considered. In all these scenarios the system installed capacity and one-hundred-year global warming potential have been investigated quantitatively.

Molybdenum disulfide, being a low bandgap prototypical transition metal dichalcogenides, is widely used in modern devices for its outstanding material properties. An attempt has been made to modulate the properties of rapid thermally grown MoS2 thin films on silicon by varying the number of spin coatings of the benzyl viologen solution. The formation of grain-like morphology with the increase in number of spin coatings of BV solution were observed from FESEM images. AFM images were used to estimate the RMS roughness of BV treated MoS2 thin films. XRD pattern depicted the presence of the (002) characteristics peak around 2θ = 14.1°. Two Raman peaks has been observed around 389 cm−1 (E12g) and 408 cm−1 (A1g) for MoS2 films. The left shift in the A1g peak position is attributed to n-type nature in BV treated MoS2 thin films. Both XRD and Raman peak intensities are found to be deteriorated, with the number of coats of BV solution. The ideality factor, built-in voltage and carrier concentration have been calculated from I-V and C-V characteristics of MoS2/Si heterojunction. The ŋ and Vbi for six number of spin coatings are calculated as 1.35 and 0.35 V, respectively. The increase in the carrier concentration of MoS2 thin films has been observed for the rise in the number of spin coatings of BV solution.

This article made a description of a novel approach that presents the utility of the various crossover techniques in the Grasshopper algorithm. The Grasshopper optimization algorithm is referred as one of the swam intelligence algorithm in the recent years. This algorithm was already applied in several field of engineering optimization. In order to provide further reinforcement to quality of the results without increasing the complexity of optimization, the crossover technique is applied in this paper. A comparison of several crossover techniques is done with a variety of benchmarking functions in order to provide a comparable platform for different category of optimization. All the technique of crossover are followed by Gaussian mutation for the enhancement of quality of results. The simulation results show the demonstration of the modified versions of the algorithm in the domain of unimodal as well as multimodal category of optimization. The results presented in this paper verified the quality of the outcome presented after suggested modification of the original algorithm. This paper helps the researchers with an elaborate idea about the planned algorithm and can act as base algorithm for several optimization applications.

This paper proposes the modeling and analysis of a three-phase four wire Shunt Active Power Filter (SHAF) based on real and reactive power (PQ) control method for power quality advancement in the electrical distribution system. The electrical distribution system contains loads like diode rectifiers with resistive load and non-linear resistive-inductive (RL) load respectively. The SHAF system construction consists of an isolation T / Hexagon winding transformer and three-phase IGBT H-bridges for voltage source inverters (VSI). It also has a tuned band-pass type passive filter. The main aims of this paper cover design, modeling, construction, and testing of a SHAF prototype for a three-phase four wire nonlinear and unbalanced system. For effective controlling action, an advanced Fuzzy-Granular controller is used in place of a traditional PI controller. This system is capable to mitigate voltage and current harmonics at a low power distribution system. The control method is developed for absorbing higher-order harmonics and store the same in the capacitor and revert it back to the system in the form of the fundamental waveform, thereby filtering action was done. The controllers based on the d-q-0 transformation technique and first-order transfer function model with three individual PWM controllers for three phases were applied to the SHAF. The proposed system is verified with PI, ANFIS, and Fuzzy-Granular controllers using MATLAB/ Simulink and compares the difference in performance.

The control method is developed for absorbing higher-order harmonics and store the same in the capacitor and revert it back to the system in the form of the fundamental waveform, thereby filtering action was done. The controllers based on the d-q-0 transformation technique and first-order transfer function model with three individual PWM controllers for three phases were applied to the SHAF. The proposed system is verified with PI, ANFIS, and Fuzzy-Granular controllers using MATLAB/ Simulink and compares the difference in performance.","PeriodicalId":436488,"journal":{"name":"2021 International Conference in Advances in Power, Signal, and Information Technology (APSIT)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130328026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
