Chapter 1. Intelligent Stand-alone Solar PV-Enabled Rainwater Harvester and Power Generator

According to UNESCO, with the existing climate change scenario, by 2030, water scarcity in some arid and semiarid places will displace between 24 million and 700 million people. In India, the paucity of water is increasing every year in a drastic way and so does the demand. This has occurred as a result of deficient planning and inappropriate management of water resources. Surface water and groundwater, which constitute approximately 40% of total precipitation, are two major sources of drinking water. It is evident that the collection of rainwater is very pivotal and beneficial. This paper illustrates the idea of conserving rainwater in an economic and renewable way by occupying free space and compact arrangement. This stand-alone system also focuses on automatic functioning of system using IoT.

Chapter 3. The Hybrid Electric Vehicle (HEV)—An Overview

The environmental impact created by automobiles is becoming a social issue day by day. To overcome these issues and save the future from worse alternative technologies like hybrid electric vehicle (HEV) and electric vehicle (EV) are required and introduced in the automobile industry. EV helps us to attain a 100-percentage clean in service. But it has infrastructure limitations and short-driving-range problems. To overcome this, we are in need of a hybrid system. HEV is a beautiful substitute for the traditional internal combustion (IC) engine-based vehicle system and reduces the problems caused by emission. It provides a suitable solution in the aspect of infrastructural limitation and reduction in operating costs. As the name suggests, HEV is a combination of IC engine vehicle and electric vehicle. Whereas IC engine vehicle runs on gasoline product and electric vehicle runs by an electric motor. Also, In HEV, the electric motor is connected with a battery pack which is rechargeable for electric motorized driving. At the same time, HEV uses both engines to increase the power and torque or depending upon the driving type, rely on anyone. This paper discusses the recent advancement of HEV, various factors involving, the challenges and the state-of-the-art solutions by automobile industries and academicians in manufacturing.

Chapter 4. Resilient Energy Storage-Based Microgrids

Recent years, deploying of microgrids become key driver due to grid power un-reliability, reduction of environmental pollution (CO2 emission) by using the renewables, demands of loads beyond the installed capacity, grid rate structure, penalties imposed due to power quality issues, incentives, etc. However, renewable energy sources will not cooperate consistently throughout the year and seasons. Changes in their availability results voltage, frequency changes causing, active, reactive power oscillations and the operation of microgrid will become unreliable. As a result, the key performances of the microgrids such as steady state, dynamic, transient response and power quality are affected. Various technical and economic challenges are introduced while integrating renewable energy sources to the utility grid. Energy storage can be a reliable asset that can bring more benefits to the microgrid. Energy storage places a critical role during the power generation fluctuations in the microgrid system due to renewables power fluctuations. It aids the microgrid to have a smooth transition from ON-grid to OFF-grid (islanded) and vice versa. In the grid connected system, it can support the real and reactive demand of the grid which can yield to shifting the energy from one time to another time. In the islanded electric system, it has the ability to operate as virtual grid for maintaining the rated voltage and frequency. Also they provide significant role in providing the spinning reserve, un-interrupted islanding, etc. In this paper, the microgrid with energy storage and renewables is analyzed in different operating conditions.

Chapter 5. Electric Traction Over Head Equipment Protection Using Intelligent Electronic Device

Protection relays used in traction system application utilize impedance protection having parallelogram characteristics with three zones of protection comprising independent R, X values with forward, reverse and independent time settings. These relays are configured to protect the 25 kV single phase 50 Hz traction transmission line which is fed from traction substation with intermediate neutral sections and insulating overlap (IOL). IOL provides further complications when the locomotive moves in this section, where the pantograph located on top of the locomotive may connect the phases of two traction substations, resulting in a wrong phase coupling scenario. Such scenarios should be detected, and the circuit has to be isolated by distance protection relay which senses the fault in the second quadrant of the R-X plane. In addition to this scenario, when regenerative breaking is applied, the moment of inertia will result in the traction motors acting as generators which will result in pumping of current into the traction line resulting in the impedance measurement in second quadrant of the R-X plane. Moreover, the distance relay algorithm is challenged by overloading condition when a locomotive enters into a section. In addition, very high resistive fault would not have sufficient current to drive the impedance relay is the additional challenge. With the availability of latest relay testing equipment, testing of these characteristics has been automated, and the process of mimicking such characteristics and testing it with smart relay testing equipment is discussed in this paper.

For an electric vehicle, battery plays a major role and needs frequent charging. For this, an efficient DC–DC converter is essential to provide ripple-free and steady output power so that the performance of the battery will not be deteriorated. This paper investigates a myriad of topologies of DC–DC converter and proposes a boost-buck converter for battery charging applications. The performance of the suggested boost-buck converter has been examined and compared with the existing non-isolated topologies. The criterion answered for comparative studies is output voltage and current ripple, input current ripple, and efficiency. From the analysis, it has been implied that the boost-buck configuration has reduced ripple and improved efficiency. Therefore, it is recommended for the battery charger. The simulation studies are executed in MATLAB software. To authenticate the simulation results, a laboratory prototype has been constructed.

Chapter 13. A Focus on Power System Congestion Management—A Primitive Review of the Literature

An increase in the involvement of distributed energy generation in the distributed systems may cause a high degree of participation of active distribution network management involving native network congestion and voltage problems. Deregulation of power system causes an increase in demand at the utility and hence results in overloading of transmission lines. To fulfill demand of power, generation companies manufacture additional output, but transmission lines are the typical ones and that they get congested as they carry additional power than its capacity. These problem areas are handled using various congestion management strategies, which play a principal role in current deregulated power systems. Hence, restructuring of power system is needed to create a shift over, where electricity is now made a artifact and has regenerated into deregulated one. In this paper, a review work is dispensed to gather related publications in congestion management. In order to reduce congestion in transmission lines, flexible AC transmission system (FACTS) devices are used, which manage the power flow to curtail losses in power system. This paper discusses the summary of congestion management in the deregulated power systems and in addition highlights the various strategies concerned to get the better of congestion in power systems.

Chapter 15. Performance Evaluation of Fast Charging DC–DC Converter for Electrical Vehicle with Root Locus-Based Digital Controller

In recent times, because of range anxiety, charging time and charging infrastructure of electric vehicles (EVs) are the main subjects to wide gap in research and development. Charging station infrastructure plays a major role in easy transition from traditional IC engine-based vehicles to EVs. The implementation of off-board fast charging for EVs with proposed control strategy aimed to facilitate the improved performance of a DC–DC converter. However, there are many analog controllers proposed in controlling converters, which lack in optimum operation of high-frequency DC–DC converter. Digital controllers provide optimum control not only in case of static input voltage but also in case of change in input voltage. At first step, pole–zero mapping is used in designing the small signal-based discrete-time model of the desired DC–DC converter. Based on discrete-time modeling, digital controller is designed using root locus technique. Lastly, simulation results are acquired for a 400 V/120 A DC–DC converter, which is used in fast charging system of electric vehicle. The analysis of the proposed controller design is presented in detail.
