Voltage sags are regarded as one of the most significant causes of disruption in power supply systems. The voltage sags cause adverse effects on sensitive equipment such as process-control equipment, computers, adjustable-speed drives, etc. During sag, the nominal voltage drops between 10% and 90% and lasts between 10ms and 100ms. Though the FACTS devices provide the solution to most of the PQ issues, it was observed that the drawback of these devices, however, is that they are very costlier. The disturbances in power lines are compensated by inserting voltages in series with the source using The Dynamic Voltage Restorer (DVR). The DVR can compensate with the proper magnitude and phase angle of the source voltage which necessitates the DVR to be operated with an independent external power source with high energy storage. This independent source may be a battery, a dc link and a capacitor bank. The limitations of such external storage usage have been addressed by many researchers, and here an attempt has been made to propose an improvised control methodology with the battery-supported DVR controlled by SRF PI control algorithm with a fast-operating DSP (Digital Signal Processor) to reduce the harmonics and to mitigate voltage sag.

The more energy we save, the less energy we would need to produce. Engineers nowadays are employing more innovative practices to increase energy efficiency. As per the International Statistical Institute, with the Gross National Income of 2020$ per capita, in the year 2018, India is still a developing country. And for the rapidly developing nations with a large population, like China and India, effective utilization of pre-existing resources is of utmost importance. The industrial sector as well the irrigation and farming populace, which are the highest consumers of electricity, need to optimize their energy consumption with adept implementation of methods such as power wheeling and cogeneration. In this paper, a case-study of a Gas Turbine Station at Damodar Valley Corporation, Maithon was undertaken with stress on wheeling of power. Cogeneration has also been studied together with the plan of Availability Based Tariff (ABT) to improve grid regulations and increase the power injected in to the grid. The issue has been simulated with the help of Genetic Algorithm Optimization Toolbox (GAOT) toolbox of MATLAB-R2016a.

This paper illustrates the design and simulation of solar powered off-board electric vehicle (EV) charging station for domestic usage by implementing different converter topologies. A typical DC off-board charger consists of a power source and a DC-DC converter for voltage correction in order to match the required nominal battery voltage at the output. If the source is given from a solar photovoltaic (PV) array, a maximum power point tracker (MPPT) is required to track the maximum power generated by the solar panel and deliver it to the converter input. There are many converter topologies currently being developed and tested to increase the efficiency of the charger. This paper selects the basic and widely used topologies which include a) DC-DC boost converter, b) single ended primary inductance converter (SEPIC) and c) full bridge DC-DC converter with high frequency transformer. These topologies are simulated using Simulink/ Matlab environment and the results are explained suitably.

This paper presents an optimal integrator control algorithm for a three-phase single-stage grid connected solar array system for improving the power quality of the distribution system under variation of solar irradiance and unbalanced grid conditions. The P&O based maximum power point tracking (MPPT) technique is used to acquire maximum power from solar array under different environmental conditions. The load stabilization, harmonic mitigation unitpowerfactor operation and reactive power mitigation is also improved using the proposed control algorithm The optimal integrator control algorithm delivers DC offset rejection in Voltage Source Converter (VSC) input voltage and reduces voltage fluctuation in the DC link voltage under varying solar irradiance. In this proposed control scheme, the main aim is to extract positive sequence of per unit phase voltage values and also to function under unbalanced grid voltages and weak grid scenarios. The results of the MATLAB show the behaviour of the system under steady and dynamic situations such as unbalanced loading and changes in solar irradiation. It is analysed from the results that the THD of source current and voltage as defined in IEEE 519 standards are achieved.

This paper proposes an off-board charging topology for electric vehicles (EVs). The proposed topology employs the concept of multi-pulse converters (MPC) for charging EV and improving the power quality of line current drawn. Specifically, the proposed topology works on grid frequency and omits the use of high frequency switches, thus improving the efficiency and minimizing the complexity of overall charging system. Explanation on the cancellation of low order harmonics in input line current by the utilization of phase shifting transformer is presented. Moreover, it is shown that the proposed topology meets the IEEE-519 power quality standards. The EV charging topology is modeled in MATLAB00AE;/Simulink environment to evaluate the power quality indexes in terms of total harmonic distortion (THD) in input line current and power factor (PF).

Continuous monitoring of the Heart of high-risk patients may have a major role in preventing coronary heart disease in recent decades. If any change of the health condition from their normal is observed, then it will be transmitted it to a health center for early and further analysis and preventative actions. This saves the life of the patients from Heart attacks. Keeping this in view we intend to develop a wireless wearable (coat) ECG (to be implemented in IOT) for detecting abnormal heart conditions. It uses a three wireless electrodes, a specialist framework focused on Java and a web-enabled surveillance network. The first move is to set up a portable ECG system utilizing the electrodes of the product click into the body region of the patient. Bluetooth will attach this lightweight ECG to mobile device like a cell phone. A mobile Java device will then begin data collection and conversion. A desktop device may be enabled. In the case of emergencies, the existing program often activates a professional alert warning device. This ECG monitoring systems are very useful for elderly patients having severe heart problems.

In this work multiple parallel photovoltaic (PV) inverter based microgrid developed to enhance the reliability and accessibility of electricity in remote areas. The employed microgrid structure designed to operate in the grid connected mode (GCM) as well as isolated mode (IAM) and vice-versa. In this microgrid, (PV)-battery interfaced main inverter with a smooth mode transition control in parallel with a PV supported inverter with an enhanced current control is considered to operate under the grid connected conditions and in the off-grid mode of operation. In IAM, the main PV-inverter works as grid forming inverter and maintained constant voltage and frequency across the load to meet the power quality for the continuous operation of local nonlinear load. The battery storage units support the PV units during peak load periods and maintain the power balance in the microgrid. Controlled charging and discharging profile of battery is achieved by the DC-DC bidirectional converter (DBC). The control strategy of microgrid has been verified with simulations are offered in this paper.

This paper deals with design and development of a light electric vehicle (EV) charger. This EV charger operates in bulk charge as well as float charge mode with the battery deep discharge cutoff to enhance battery life. Its power converter is of 85W rating having operating voltages from 36V to 42V with 2A maximum current in bulk charge mode. Test results are presented for a 36V, 10Ah-20Ah battery, which is commercially used for electric cycle or equivalent EV application. The input voltage for this power converter is for universal input voltages (90VAC -265VAC/47Hz-63Hz). The AC-DC converter power switch operates in quasi-resonant mode for high efficiency in wide input voltage range. The converter size as well as thermal parameters are well within the limits as observed in test results.

An Electric Vehicle (EV) charger, also called Electric Vehicle Charging Station (EVCS) is an infrastructure element that supplies electrical energy for recharging EVs. The paper focuses on the design and fabrication of two-wheeler (escooter) electric vehicle charging equipment. Considering the future scenario of mass privatization of EV two-wheelers on Indian roads, the outline discusses the product design based on fabricability, affordability, and ability to mass manufacture. The proposed architecture follows the Level 2 charging standards (240 Volts), and is based on the open charge point protocol (OCPP). The suggested EVCS is constructed considering the safety prerequisites of system administrators, installers, consumers, government agencies and others. The design of EVCS links to three industries: equipment manufacturers, software industry and electric power networks. This paper presents design considerations by elaborating the hardware, software, and protocols followed to design the Level 2 charging standard EVCS.

The frequency and voltage level determines the quality of the power system. The control and stability becomes more complicated in case of a deregulated power system due to multiple bilateral transactions. The inclusion of delay further complicates the load frequency control. This paper deals with the modelling and designing of a controller for load frequency control in an interconnected two area non-reheat deregulated power system considering the effect of time delay. LMI based feedback controller is designed to maintain system frequency. The ascendancy of the LMI based controller over the genetic algorithm optimised integral controller is also demonstrated.
