Keterbatasan listrik di dusun Bunga Tanjung desa Rantau Binuang Sakti menyebabkan ketidaknyamanan masyarakat. Berbagai kegiatan tidak dapat dilakukan dengan leluasa karena terbatasnya listrik. Tersedianya mesin Diesel bantuan pemerintah daerah hanya dapat dimanfaatkan mulai jam 18.00 hingga jam 24.00 malam. Hal ini tentu mempengaruhi kegiatan masyarakat antara lain proses belajar mengajar murid-murid sekolah SD dan SMP yang terdapat di desa tersebut. Selain itu, penggunaan mesin Diesel memberatkan masyarakat dari segi biaya operasional. Lokasi desa yang jauh dari jangkauan PLN (40 km) serta jumlah masyarakat yang tidak terlalu ramai (hanya 3 dusun) tidak efektif untuk dibangunnya jaringan listrik oleh PLN. Permasalahan inilah yang menjadi ide dasar bagi program IbM ini. Desa Rantau Binuang Sakti merupakan daerah yang memiliki cukup banyak sungai terutama yang besar adalah sungai Rokan yang berpotensi untuk menggerakkan kincir air yang digunakan untuk membangkitkan energi listrik. Dusun Bunga Tanjung ini menjadi objek pelaksanan  program IbM terletak pada daerah aliran sungai (DAS) Rokan. Pembangkit listrik tenaga kincir air ini merupakan solusi untuk mendapatkan listrik yang secara terus menerus karena sumber energi utamanya adalah dengan memanfaatkan aliran air sungai sebagai penggerak generator listrik.. Kincir air yang dirancang menggunakan pondasi ponton untuk menjamin sudu-sudu kincir tetap bekerja pada saat permukaan air berubah-ubah. Arus sungai yang melewati sudu-sudu kincir diarahkan kesaluran yang berbentuk konvergen sehingga kecepatan air yang melewati sudu akan lebih cepat dibandingkan arus air yang diluar ponton. Rancangan ini mempercepat putaran kincir untuk ditranmisikan ke generator lisrtik. Dengan demikian energi listrik yang dihasilkan bias dimanfaatkan untuk penerangan jalan di pinggir sungai dan kebutuhan lainya untuk masyarakat setempat.

Authors: Beeharry Yogesh , Fowdur Tulsi P. , M. S. Soyjaudah Krishnaraj
Published: March 2020

Binary and Non-Binary Turbo codes have been deployed in several digital communication standards to perform error correction. In order to enhance their error performance, several schemes such as Joint Source Channel Decoding (JSCD), extrinsic information scaling mechanisms, and prioritized QAM constellation mapping have been proposed for improving the error performance of error correcting codes. In this paper, hybrid schemes comprising of JSCD, regression based extrinsic information scaling, and prioritized 16-Quadrature Amplitude Modulation (QAM) with binary and non-binary Turbo codes have been presented. Significant improvement in error performance has been observed with the proposed scheme as compared to the conventional one. The hybrid scheme in the case of binary symmetric and asymmetric LTE Turbo codes, and triple binary Turbo codes outperform the conventional scheme by 0.8 dB on average. With duo-binary Turbo codes for the DVB-RCS standard, the hybrid scheme outperforms the conventional one with an average gain of 0.9 dB in BER performance.
Fractional Order PID Controller Design for DC Motor Speed Control System via Flower Pollination Algorithm
Authors: Puangdownreong Deacha
Published: March 2020

Over two decades, the fractional (non-integer) order PID (FOPID or PIλDµ ) controller was introduced and demonstrated to perform the better responses in comparison with the conventional integer order PID (IOPID). In this paper, the design of an optimal FOPID controller for a DC motor speed control system by the flower pollination algorithm (FPA), oneof the most efficient population-based metaheuristic optimization searching techniques, is proposed. Based on the modern optimization framework, five parameters of the FOPID controller are optimized by the FPA to meet the response specifications of the DC motor speed control system and defined as constraint functions. Results obtained by the FOPID controller are compared with those obtained by the IOPID designed by the FPA. As the simulation results show, the FOPID can provide significantly superior speed responses to the IOPID.

Authors: Sohoni Vaishali , Gupta Shivcharan , Nema R. K.
Published: March 2020

The aim of this study is to design renewable energy based hybrid standalone systems to supply two rural and one urban sites of Madhya Pradesh state in India. These locations characterize different load profiles and wind and solar resources. The wind speed data measured at these sites and solar radiation data obtained from NASA are utilized to carry out theanalyses of these systems using HOMER Pro. These systems are designed to cater for domestic electricity demand of one rural site, domestic and agricultural demand of another rural site and residential load demand of staff quarters of an urban institution. The pattern of power consumption of the loads considered for these sites is suitably modelled and different combinations of hybrid systems are simulated to identify the optimal system based on least life cycle cost. Results show that the most economically feasible system to supply the load demand of the three sites is comprised of different combinations of renewable energy sources viz. only wind, wind- solar and only solar based systems. Each design also includes diesel generator back up and battery storage to ensure reliability of power supply and a converter to maintain the energy flow between ac and dc components.

Authors: Sudabattula Suresh Kumar , Muniswamy Kowsalya , Suresh Velamuri
Published: March 2020

Performance of a distribution system is negatively affected with the usage of non linear loads and rapid growth in electricity demand. It is possible to improve the voltage profile and reduce the power loss in a distribution system, by integrating distributed generators (DGs) and shunt capacitors (SCs). Identifying the optimal location and capacity of DGs and SCsare the crucial factors affecting the DS performance. This paper aims to reduce the power losses in the DS and facilitates an improvement in voltage profile with optimal allocation of DGs and SCs. First, the vulnerable nodes for placement of DGs and SCs are identified by loss sensitivity factor (LSF) technique. Next, the sizes of SCs and DGs at these corresponding locations are determined using a recently developed swarm intelligent technique dragonfly algorithm (DFA). Various constraints of the DS are included to estimate the objective function. To analyze the performance of the proposed method it is investigated on IEEE 69 bus radial distribution systems (RDS) considering constant power load at different load levels. Several case studies are conducted to analyze the performance of the DS. Three different load levels at different power factors are considered in the study. Initially few case studies are performed by considering single DG and single SC. Further the analyses are extended with multiple DGs and SCs. Finally, the proposed method is compared with other prominent methods accessible in the literature. It can be inferred from the analyses that simultaneous allocation of DGs and SCs in DS improves the overall performance of the system.

Published: March 2020

The integration of plug-in electric vehicles (PEVs) to the conventional distribution system has had a major impact upon consumption of energy in the past year. This paper presents optimal distributed generator (DG) sizing and location in the power system using PEVs load demand probability. The MATLAB m-file scripts and OpenDSS were applied to solve the proposed study by varying the percentage penetration level of PEVs. A genetic algorithm optimization technique was used to find the best solution of DG installation. The simulation results showed thatthe PEVs were directly connected to the power grid with 100 PEVs (13.84%), 200 PEVs (27.68%) and 500 PEVs (69.19%), respectively. It was found that the DG sizing also varied with 1.773 MW, 1.663 MW and 1.996 MW, respectively. While the position of the DG also changes according to the sizing of DG. The position of DG was installed at bus No.738, bus No.741 and bus No.711, respectively. Therefore, the optimal DG placement helped to improve and reduce the total line loss and total energy demand from the power grid. The grid increased the power system stability and reduced the impact from the large scale of PEV penetration.
Modified Venturini Modulation Method for Matrix Converter Under Unbalanced Input Voltage Conditions
Authors: Jarutus Neerakorn , Kumsuwan Yuttana
Published: March 2020

Based on Venturini method, it is in favor of the modulation technique for controlling the matrix converter due to only use of the comparison between the duty cycles in time domain and the triangular carrier wave for generating the gating signals and the achievable voltage ratio between fundamental output magnitude and fundamental input magnitude to 0.866. However, even with simple modulation method and achieving maximum fundamental output magnitude, the possible input voltage unbalance conditions accordingly influence on the output performances (more reduction and distortion). Thus, a control strategy based on Venturini method is presented in this paper, in order to solve the impacts of unbalanced input voltage conditions on the matrix converter performances. Conceptually, this strategy is done by modifying the mathematical model for controlling the modulating waves to satisfy the desirable feature, as generated in the event of normal situation. Up to this approach, it can support either single-phase condition or two-phase condition. Performance of the proposed control strategy was verified by the simplified simulation model in the MATLAB/Simulink software. It is clearly shown that the matrix converter can be controlled for regulating the balanced output voltages with showing good steady-state and dynamic operations without the energy storage devices.
Optimal Fuzzy Sliding Mode Controller Design using Bee Algorithm for Dynamic Voltage Restorer System
Authors: Tiacharoen Somporn , Chatchanayuenyong Theerayuth
Published: March 2020

This paper proposes an application of the bee algorithm (BA) in order to design an optimal proportional-integral-derivative (PID) controller, a sliding mode (SM) controller, and a fuzzy sliding mode (FSM) controller for a dynamic voltage restorer (DVR) system. The DVR is an electronic device, which has excellent dynamic capabilities and is well-suited in protecting critical or sensitive loads from short duration voltage sags or swells. The parameters of the optimal PID, SM, and FSM controllers are automatically tuned by the BA to compensate for the magnitude of load voltage by injecting the compensating voltages when the source voltage sags and swells. In order to confirm these concepts and to show that the proposed strategy outperforms other strategies when it is compared to others using the trial and error method, experimental and simulation setups were implemented in various cases.

A New Copyright- and Privacy-Protected Image Trading System Using a Novel SteganographyBased Visual Encryption Scheme
Authors: Sae-Tang Wannida , Fujiyoshi Masaaki , Kiya Hitoshi
Published: March 2020

In copyright- and privacy-protected image trading systems, the image sent to the trusted third party (TTP) is visually encrypted, and the image is traditionally unrecognizable. The image, however, is suspicious and has possibility to be attacked. Image steganography then becomes more interesting than image encryption for this application, however, applying image steganography instead of image encryption degrades the fingerprint extraction performance. In addition, the CP is allowed to directly contact with the consumer in the conventional systems. Thus, the consumer’s privacy is not protected completely. This paper then proposes a new copyright- and privacy-protected image trading system with a novel steganography-based visual encryption scheme, where the scheme protects a commercial image much more securely by generating a recognizable image instead of a suspicious encrypted image. By replacing amplitude components of a dummy image by those of a commercial image, the output image looks like a degraded dummy image instead of the commercial image, while it contains some details of the commercial image, i.e., the amplitude components of the commercial image are hidden into a dummy cover image. A discrete cosine transform-based fingerprinting method, which is compatible with the proposed amplitude component replacing scheme, is also proposed in this paper to solve the problem of applying image steganography. As another contribution of this paper, the CP is not allowed to directly send the image reconstruction key to the consumer, for further consumer’s privacy protection. The second TTP is then introduced to the proposed system, and in addition, the image reconstruction key is encrypted by the CP before being sent to the consumer via the second TTP for more security. Experimental results show that the proposed scheme generates recognizable images and perfectly visually encrypts the commercial images. It also achieves much higher reconstructed image qualities than those of the conventional scheme, and the proposed system simultaneously enhances the fingerprinting performance using the proposed compatible fingerprinting method.

Authors: Channarong Nontapat , Leelavattananon Kritsapon
Published: March 2020

This work presents a new pulse-shaping technique for an impulse-radio ultra-wideband (IR-UWB) transmitter which is intended for RFID tags and wireless sensor applications. The proposed pulse is derived from a rectangular pulse with its side-band energy suppressed in order to satisfy the FCC UWB regulation, in particular at low frequency band (3.1 - 4.8 GHz). To verify its effectiveness, the new pulse generator was designed in a 180-µm CMOS process. The simulation results indicate that the spectrum of the transmitted pulse can be fitted within the FCC UWB spectral mask. The total circuit consumes 926 µW at a 10 MHz pulse repetitive frequency (PRF).
Features of Smart Grid Technologies: An Overview
Authors: Kim Seong Cheol , Ray Papia , Reddy S. Surender
Published: March 2020

This paper presents an overview of smart grid (SG) technology features such as two-way communication, advanced metering infrastructure (AMI) system, integration of renewable energy, advanced storage techniques, real time operation and control, data management and processing, physical and cyber security, and self-healing, etc. The SG technology allows twoway communications for better reliability, control, efficiency and economics of the power system. With these new SG technologies, consumers have many energy choices, such as use of renewable energy, usage management, flexible rates, electric vehicles (EVs), etc. The requirement of these technologies is the real time operation, and the SG accommodates this realtime operation and control. SG technology allows distributed generation through demand response and energy efficiency technologies to shed the load demand. However, it’s very difficult to adopt these changes to the conventional grids. Utility companies, governments, independent system operators (ISOs) and energy regulatory commissions need to agree on the scope and time frame of these changes.

Published: March 2020

Malaysia has been ranked as one of the country in the world with deadliest road. Based on the statistic, there are around 7000 to 8000 people in the country died on the road among the population of 31 million Malaysians every year. In general, Advances Driver Assistance System (ADAS) aims to improve not only the driving experience but also consider the overall passenger safety. In recent years, driver drowsiness has been one of the major causes of road accidents, which can lead to severe physical injuries, deaths and significant economic losses. In this paper, a vison-based real-time driver alert system aimed mainly to monitor the driver’s drowsiness level and distraction level is proposed. This alert system could reduce the fatalities of car accidents by detecting driver’s face, detecting eyes region using facial landmark and calculating the rate of eyes closure in order to monitor the drowsiness level of the driver. Later, the system is embedded into the Raspberry Pi, with a Raspberry Pi camera and a speaker buzzer, and is used to alert the driver in real-time, by providing a beeping sound. Experimental results show that proposed system is practical and low-cost which could (1) embed the drowsiness detection module, and (2) provide alert notification to the driver when the driver is inattentive, using a medium loud beeping sound, in real-time.

The ideal example for studying complex systems with non-holonomic constraints is mobile-wheeled robots. In this article, we study the problem of trajectory tracking of mobile robot unicycle type. To resolve this type of problem a fractional-order control technique is proposed. The main objective of this control method is to design a robust tracking controller to eliminate disturbances. The mathematical model of the mobile robot taken explicitly into account their dynamics is used to calculate the desired linear and angular velocities. To adjust the controller optimal parameters the particle swarm optimization (PSO) algorithm is utilized. The simulation results allowed us to demonstrate the efficiency and robustness of this technique on non-holonomic systems in the form of chained chains.

Nowadays, new trends in the industry of electricity generation are to enhance the power generation by employing distributed generation (DG) system which is mostly based on renewable generation sources such as wind, solar, etc. However, many power quality problems could arise on existing grid when DG is connected or the operation of distributed energy resources (DER) is not controlled properly. That's why, while integrating DG with the power grid, a seamless attention should be given to power generation and safe running of system. Several methods, having a diverse concept, have been divided into two main sets: linear and nonlinear controllers. The first group comes with PI controller and parameter feedback controller, and control by means of constant frequency with predictive techniques. The second group includes hysteresis current control and on-line optimization for predictive controllers. Additionally, new current control techniques with neural networks and fuzzy based controllers are also discussed. Selected methods associate the arrangement for the sake to demonstrate the described groups of the controller.

Authors: Chopra Namarta , Brar Yadwinder , Dhillon Jaspreet
Published: March 2020

This paper presents the solution of economic power dispatch (EPD) in thermal power plants using the hybridization of particle swarm optimization (PSO) and simplex search method (SSM). EPD is obtaining the best generating schedule to supply the power demand and covering the transmission losses with minimum overall fuel cost. Physical constraints like valve point loading effects, ramp rate limits and prohibited operating zones are also included with basic EPD problem to increase the practicability in the problem. As PSO performs well in finding the global best solution and SSM in finding the local best solution, thus their combination improves the overall minimum results obtained for the generation fuel cost objective function. The performance of the proposed methodology is tested on different test systems having categories of small-scale, medium-scale and large-scale power system problems. The results obtained are then compared with other reported methods to show the superiority of the proposed algorithm.

This paper deals with the flatness-based approach for sensorless control of the three-tank system. Two main characteristics of the proposed control deserve to be mentioned. Firstly, the relative simplicity of implementation compared with the other advanced output feedback controller. Secondly, the estimation of the non-measurable states using a continuous-discrete time observer which can provide, even for weakly sampled output, all the missing states. Simulation and experimental results show the applicability and the efficiency of the proposed control scheme

Published: March 2020

The current study aimed to determine the effect of the seasons on the scrotal circumference, serum concentration of testosterone and some of the chemical parameters in Nuaimie breed rams in Salah-din province. Thirteen Nuaimie rams were used in this study. They were 3-4 years old and weighed 45-55 kg reared in a herd of sheep in Tikrit for the period from 15-8-2016 to 15-7-2017. Results showed that the scrotal circumference increased significantly (P≤0.05) during autumn (30.58±0.54 cm) and reaches lowest value during summer (29±0.32 cm). Highest concentration (P≤0.05) of testosterone was recorded in winter and autumn and lowest concentration in the spring and summer. The chemical analysis of ram blood serum revealed that the season has an effect on the value of triglyceride, glucose and cholesterol and the significant increase were recorded in autumn and winter. In conclusion, the reproduction in Nuaimi breed rams is characterized by distinct seasonal variations in scrotal circumference and blood testosterone concentration and that the highest measurements of these parameters are in autumn season. The season has a clear effect on the levels of triglycerides, glucose and cholesterol in ram's blood serum, which may give a good indication of reproductive performance in rams.
