This paper proposes a new fuzzy logic controller for seven-level hybrid cascaded H-bridge inverter. The inverter is used for on-grid application of PV a system. Here a Sinusoidal pulse width-modulation (SPWM) technique is applied for obtaining carrier signals. Multi-Level Inverter technology have been developed in the area of high-power medium-voltage energy scheme. It is because of their advantages such as devices of high dv/dt rating, higher switching frequency, unlimited power processing, shape of output waveform and desired level of output voltage, current and frequency adjustment. This topology can be used there by enabling the scheme to reduce the Total Harmonic Distortion (THD) for high voltage applications. The Maximum Power Point tracking algorithm is also used for extracting maximum power from the PV array connected to each DC link voltage level. The Maximum Power Point tracking algorithm is solved by Perturb and Observer method. It has high performance with low Total Harmonic Distortion and reduced by this control strategy.

Smart dust is a tiny dust size device with extra-ordinary capabilities. Smart dust combines sensing, computing, wireless communication capabilities and autonomous power supply within volume of only few millimeters and that too at low cost. These devices are proposed to be so small and light in weight that they can remain suspended in the environment like an ordinary dust particle. These properties of Smart Dust will render it useful in monitoring real world phenomenon without disturbing the original process to an observable extends. Presently the achievable size of Smart Dust is about 5mm cube, but we hope that it will eventually be as small as pack of dust. Individual sensors of smart dust are often referred to as motes because of their small size. These devices are also known as MEMS, which stands for micro electro-mechanical sensors.

PHEV is a hybrid electric vehicle that uses rechargeable batteries or another energy storage device that can be recharged by plugging it into an external source of electric power. By using the PHEVs with grid connection we can decrease the fossil fuel consumption, therefore it provides stability, voltage control and frequency control. Uncoordinated charging of plug-in hybrid electric vehicles (PHEVs) will produce a series of negative effects on the electric grid. To solve this problem, we have to make smart-charging strategy by knowing PHEV charging characteristics. Here we use a bidirectional ac-dc converter and a bidirectional dc-dc converter. The main objective is to use bidirectional switching converter for PHEV to obtain high energy density, low volume and low weight. With the help of these bidirectional converters the excess charge in battery after charging PHEV can be fed back to the grid which can be utilized for load demands. This bi-directional charger must have the capability to charge a PHEV’s battery pack while producing minimal current harmonics and also have the ability to return energy back to the grid in accordance with regulations. There are two modes of operations i.e. charging and discharging modes of battery. The ac-dc controller act as a regulator during charging mode and as an inverter during discharging mode. Also, we use integrated controller for both modes to obtain performance of battery.

This paper describes a very simple & generic model of evaluating the overall performance of approved vendors in respect of an engineering industry. A product consists of thousands of parts and some parts need to be procured from outside vendors based on “Make or buy” decision. Thus manufacturing & vendor development are two sides of the same coin. The vendors of regular inventory are considered for evaluation. A poor performance by even a single vendor will have a telling impact on the production in the company. Hence vendor evaluation/rating assumes significance. This method takes into account five criteria such as Quality, Price, Delivery, Service & Support. The first three are objective in nature & last two are subjective in nature. The provision of negative marks is also indicated here. The overall performance rating is a numerical value. Based on this value, vendors are graded into three categories such as high, mediocre & poor performers. This gives an opportunity for the company management where to focus and also vendors will come to know where they stand & how to improve. This model is widely accepted in mechanical engineering industries. This will ultimately result in good vendor relations which is the need of the hour.

We all know that electricity is a part of our day today life and its demand has increased considerably due to the rise in the population. In order to supply power to the consumers, it has to be transmitted with minimum amount of losses such that the power system provides better efficiency. For this purpose, generation, transmission and distribution must be efficiently carried out considering all the factors in order to reduce losses and increase the power outcome. Transmission line (TL) plays an important role in transmitting electrical power. This paper deals with the maintenance of overhead (OH) TL by using a robot, which monitors the TL and detects any fault if present, so that electricity is transmitted with minimum amount of losses. Maintenance and detection of any kind of faults in the TL is a difficult task we face then and now because of risky factor while dealing with high voltages. Usually inspectors carry line inspection by aviation method which includes an observer who observes the TL by a helicopter driven by a pilot which is indeed a costly one and the video images provided from the helicopter is out of focus. Hence in order to achieve the same a robot is used which travels on the TL with the help of rollers on it. The robot inspects the TL and transfers the data regarding the line faults directly to the control room. In this method, the robot is equipped with a voltage and current sensor for the measurement of voltage and current, a RF module for communication purposes and a visual camera to capture images to be sent to the control room. This method is so advantageous in reducing cost, increasing efficiency and enhancing safety.

Grid connection capability of distributed generation attracts researchers due to the cumulative demand for electricity and environment pollution concern as a new emerging technology for providing reliable and clean power supply. A microgrid comprises distributed generation, energy storage, loads, and a control system that is capable of operating in grid-tied mode and/or islanded mode. As operation modes are shifted, the microgrid should successfully manage the voltage and frequency adjustment in order to protect the grid and any loads connected to the system. Facilitation of the generation-side and load-side management and the resynchronization process is required. This paper presents an overall description and typical distributed generation technology of a microgrid. It also adds a comprehensive study on energy storage devices, microgrid loads, interfaced distributed energy resources (DER), power electronic interface modules and the interconnection of multiple microgrids. Details of stability, control and communication strategies are also provided in this study. This article describes the existing control techniques of microgrids that are installed all over the world and has tabulated the comparison of various control methods with pros and cons. Moreover, it aids the researcher in envisioning an actual situation using a microgrid today, and provides insight into the possible evolvement of future grids. In conclusion, the study emphasizes the remarkable findings and potential research areas that could enrich future microgrid facilities.

Wireless power transmission technology enables flexible comfortable supplying energy needs to electric devices. However, the wireless power transmission technologies that use the magnetic field resonance method have various problems. Much of the research is often focused on the efficiency between resonators. The relationship between the internal resistance and efficiency is not clear. The efficiency at high output power is not well understood. Practically adding an internal resistance as an equivalent of both of rectifier and inverter losses is important for efficiency calculation. Even if the wireless power transmission has high efficiency it is not suitable for practical use if the output power rating is very small. We can increase transmission power in accordance to the principles of the LC cancellation by using the resonance phenomenon even at a small coupling coefficient.

An experimental implementation of a standalone microgrid topology based on a single voltage source converter (VSC) and brushless generators. The microgrid system is energised with different renewable energy sources namely wind and solar PV array. However, a diesel generator (DG) set and a battery energy storage system (BESS) are also used to maintain the reliability of the system. The proposed topology has the advantage of reduced switching devices and simple control. The implemented topology has DG set as an AC source. The wind generator and the solar PV array are DC sources which are connected to the DC link of the VSC. The BESS is also used at the DC link to facilitate the instantaneous power balance under dynamic conditions. Two controllers for generator, PV and Wind are explained in which one is simulated using Matlab Simulink and Output is obtained.

Standby power refers to the electrical energy that is used by devices even when they appear to be turned off. Standby power allows electronics to turn on quickly, but means that they are constantly drawing some power from the electrical grid. Many electronic appliances consume standby power, which as per IEC definition is the equipment’s' lowest level of power intake while in switched on but idle state. The users of these devices are often unaware of such continuous power drain. Computers, that enable better productivity and accuracy, are in common use today. Personal Computers (PC) need stable power inputs that can deliver rigidly regulated and isolated DC outputs of high power quality at different levels. However, the standby power associated with Personal Computers is substantial. Therefore, the primary objective of the project is to develop a Switch Mode Power Supply (SMPS) that integrates with a battery that is charged by solar energy. The battery provides standby power of the requisite quality to the Pc. Power factor is improved using buck-boost PFC converter in Discontinuous Conduction Mode at the front end. Simulation of the suggested model implemented in Matlab/Simulink Software has demonstrated improved performance for the proposed Hybrid SMPS.

Automatic monitoring of vehicle has become a very essential scenario in the recent years and it can become possible by implementing the following technology. The beginning of the 21st century was the time when importance for Environmental awareness was instigated. One of the major concerns regarding the environment is air pollution. The main pollutants from the vehicles are the oxides of carbon and nitrogen, which can be easily detected these days with the help of semiconductor gas sensors. The system consists of a global positioning system, an IoT module and a GSM board. The gas sensor detects the gas produced due to over pollution and the micro-controller board determines the proportion and if it is higher than the stated limit as per the Bharat Stage 6 norms, the GPS system sends the co-ordinates to the nearby RTO. The warnings received will be saved and if the warnings exceed more than three times or if the pollution level raises drastically the vehicle automatically provides navigation to a nearby safe zone. The safe zones are detected automatically with the help of IoT and GPS technologies. A vehicle speed monitoring sensor is used and is coupled with the IoT so as to reduce the speed of the vehicle at specific places, say school zones, hospitals, accident prone zones etc,. If this technology is employed the parameter of safety and reduction in pollution levels as well as prevention of accidents can be achieved.

In modern society, an increasing number of electrical loads in buildings, such as computers, consumer electronics, light emitting diodes (LEDs), or variable speed motors, are supplied by dc power. At the same time, distributed renewable sources such as photovoltaics (PV), as well as batteries for electric vehicles and on-site storage, are based on dc. To integrate these technologies into existing ac power systems, complicated dc/ac inverters and controllers are required to synchronize with ac systems and to provide high-quality ac currents without harmonics. DC power systems can integrate dc renewable generation, storage, and building electrical loads easier and more efficiently than conventional ac based systems. A key challenge for the successful market adoption of these systems is the integration with existing electrical loads and power grids in buildings. Hybrid ac/dc microgrids combine advantages of both ac and dc systems and may facilitate the integration process of dc power technologies into existing ac systems. In this work, the performance of a hybrid building microgrid coupling on-site PV generation with ac and dc loads of a residential building is investigated in simulation. An experimental dc network prototype, coupling PV electricity generation to LED lighting in a building, has been built and tested. Theoretical and experimental results are used for the design of a hybrid microgrid, planned to be implemented together with the PV system of a residential research buildings.

Microgrids are local small scale electricity systems that can operate independently and separated from the main electricity grid. This paper presents a novel unidirectional DC/DC converter that can be used to transfer power from distributed resources such as Solar PV or Fuel Cells into a DC microgrid. The converter is based on the LLC topology but designed to operate in a specific region of the gain curve that provides several benefits to integration of renewable energy sources into a constant DC bus. The isolated converter shows very high efficiency, full range of zero current switching, and simple control. The novel topology also has the inherent attribute of balancing the voltage on a bipolar DC bus by automatically shifting the processed power to the pole with the lower voltage.

Solar energy is very important means of expanding renewable energy resources. In this paper is described the design and construction of a microcontroller based solar panel tracking system. Solar is a nonconventional source of energy, considering this we have developed solar panels so that we can fulfill our electricity need. But due to revolution of the earth, solar source i.e. sun does not face the panel continuously hence less electricity is produced. The energy panel should face the SUN till it is present in a day. The problem above can be solved by our system by automatic tracking the solar energy. The block diagram below shows system architecture it consist of a LDR sensor senses max solar power which is being given to the Microcontroller through the ADC which digitizes the LDR output. Controller then takes the decision according to then algorithm and tilts the panel towards the direction of the max energy given by LDR with the help of DC Motor.

This paper focuses on addressing the issue of portable water scarcity, prevalent in various part of the world. There is a need to employ various expensive methods to transform the brackish water to standard potable water. The traditional methods of brackish water desalination deployed, namely the Reverse Osmosis Technique (RO) and the distillation processes are expensive in implementation and operation. This paper introduce a new concept “CAPACITIVE DEIONIZATION” to solve this problem. It is an energy efficient technology that provide an ideal alternative solution to this problem. In this technique remove the salt ions from the brackish water instead of removing pure water from brackish water like in the conventional reverse osmosis system. Thin film composite membranes of AEM Type-1 and CEM Type-1 are employed for collecting the respective ions which are separated by means of application of low value of dc voltage. It requires the usage of significantly less direct current energy for operation. This introduced system is enhanced by the utilization of solar energy so as to incorporate the most abundant renewable energy source available. This model which exhibits extreme potential of application mainly in remote locations which are devoid of proper access to conventional sources of energy and WHO specified standard potable drinking water.

For energy, environment, and many other reasons, the electrification for transportation has been carrying out for many years. In railway systems, the electric locomotives have already been well developed for many years. A train runs on a fixed track. It is easy to get electric power from a conductor rail using pantograph sliders. However, for electric vehicles (EVs), the high flexibility makes it not easy to get power in a similar way. The problem for an electric vehicle is nothing else but the electricity storage technology, which requires a battery which is the bottleneck today due to its unsatisfactory energy density, limited life time and high cost. Wireless power transfer (WPT) using magnetic resonance is the technology which could set human free from the annoying wires. In fact, the WPT adopts the same basic theory which has already been developed for at least 30years with the term inductive power transfer. WPT technology is developing rapidly in recent years. The advances make the WPT very attractive to the electric vehicle (EV) charging applications in both stationary and dynamic charging scenarios. Here uses reviews of the technologies in the WPT area applicable to EV wireless charging. By introducing WPT in EVs, the obstacles like charging time, range, and cost can be easily mitigated thus battery technology will no longer be relevant in the mass market penetration of EVs. It is hoped that researchers could be encouraged by the state-of-the-art achievements, and push forward the further development of WPT as well as the expansion of EV.

In recent years, research on wireless power transmission technologies has been attracting more attention after MIT introduced the magnetic resonance technology in 2007. Wireless power transmission technology enables flexible comfortable supplying energy needs to electric devices. However, the wireless power transmission technologies that use the magnetic field resonance method have various problems. This method has been uniformly investigated from different directions. Therefore, it is difficult to understand the principle for such new technology phenomenon. Much of the research is often focused on the efficiency between resonators. Moreover, the relationship between the internal resistance and efficiency is not clear. Furthermore, the efficiency at high output power is not well understood. Practically, adding an internal resistance as an equivalent of both of rectifier and inverter losses is important for efficiency calculations. Even if the wireless power transmission has high efficiency, it is not suitable for practical use if the output power rating is very small. In this study, at first, the drawbacks of using the electromagnetic induction method for wireless power transmission are described in detail. Then, we indicate that we can increase the transmission power in accordance to the principles of the LC cancellation by using the resonance phenomenon even at a small coupling coefficient. After that, the difference between the overall efficiency considered of entire system and the transmission efficiency between the resonators is clearly distinguished. Then a theoretical formula has been developed for the overall efficiency and the output power in terms of the characteristic impedance. Finally, the theoretical results are compared with the experimental results and discusses in detail.
