The Virtual Conference on Recent trends on Renewable Energy, Smart Grid, and Electric Vehicle Charging is a platform for researchers, academics as well as professionals from all over the world to present, discuss and promote advances in knowledge, research, and practice in the field of Smartgrid, Renewable Energy Integration, Energy Storage System, Power Quality in Smart Grid, Transactive Energy Systems. RESGEVT-20 offered fantastic opportunity to all the global researchers to share their view through digital platform without any restrictions due to COVID-19.RESGEVT-20 focuses on renewable energy, smart grid, and electric vehicle charging technology. Renewable energy, and smart grid technology has a way for a solution for better generation of electric power and an efficient way for transmission and distribution of this power. Due to its versatility it can be more easily installed and required less space as compared to traditional grids. Concept of Smart Grid design is aimed for grid observability, create controllability of assets, enhance performance and security of power system and specially the economic aspects of operations, maintenance and planning. That’s why it is also consider that smart grid technology can be used to micro-grid level which eventually connect to all other micro-grids to form a large network of Smart Grid. These smart grids have a huge potential and could be a solution of reliability of power transmission and distribution in developing countries which lack infrastructure. In US only 20% of the all carbon dioxide is been emitted by transportation while generation of electricity has 40% of the carbon dioxide emitting share in it. This is due to the high demand rise of electricity. Smart Grids are been considering as a key role to address this problem by distributing electric power in an efficient way and ultimately reduce greenhouse gasses and pollutants like NOx and Sox.The virtual conference RESGEVT 20 was organized by Centre for Smart grid Technologies, School of Electrical Engineering, Vellore Institute of Technology, Vellore, India.

We have been witnessing for several years the increasing networking of objects of all kinds that were not previously used to communicate. These newly connected objects together form the concept of Internet of Things (IoT). The energy sector is currently exploring the possibilities offered by the Internet of Things. However, for this sector, network intelligence is not a completely new phenomenon. The electrical networks already have information retrieval capacities for their monitoring and control, but these are still limited. The meeting of IoT and Smart Grids opens the way to data collection from all points of the network and in real time. Certain data previously collected in an aggregated manner over large geographic areas could now be collected on a local scale, near production or transmission points, and at a reasonable cost. It is also the massive accumulation of this data and its processing that is possible today. The smart grid is a network for the transport and distribution of electricity that is enhanced by capacities in terms of digital control, surveillance and telecommunications. It provides a two-way, real-time exchange of energy and information between the various players in the electricity chain, from the production site to commercial, industrial and residential users. The energy transition and the new smart grids raise many challenges in terms of industrial cybersecurity. Digital exchanges are intensifying (production, distribution and consumption are interconnected) and the use of connected objects (facilitating remote monitoring, observation and control of the entire value chain) increases the degree of vulnerability of information systems industrial. The cybersecurity of smart grids is today a decisive element in ensuring global security of our global energy systems. The purpose of this work is to present a comprehensive overview of challenges, threats and some solutions of security in IoT based smart grid. We focus in our study in network vulnerabilities, security requirements and cyber-attacks in smart grid in order to determine their impact in the network and give a guide on future research directions for cyber-security in smart grid applications.

The development in the field of power electronics has led to its optimum and efficient use in domestic and industrial arena especially in control and automation processes. In turn this has created a threat in terms of power quality issues. To some extent solution to power quality issues is obtained again using power electronic devices in the form of active filtering. A shunt active power filter (SAPF) is used for harmonic filtering. The performance of such system is enhanced by using multilevel inverters. A novel three level inverter topology is proposed here. A three phase transformer fed from both ends at its primary terminals with two independent voltage source inverters is used to replace a filter inductance of a conventional system. The benefits of multilevel inverter are utilized in SAPF and also system power factor is kept near unity in all conditions.

The article analyzes the international experience of improving energy efficiency due to increasing the level of energy production from renewable sources and technological changes. Empirical verification of the related hypothesis has been carried out for the USA, China, India, Germany and Russia using econometric tools. The necessity of the transition to a new energy structure based on the active introduction of energy-efficient technologies, renewable energy sources, integrated systems and intellectual energy services based on an open grid architecture is substantiated. The posed hypotheses confirm the following: the production of energy from renewable sources is increasing in all countries, not only in the countries with the lack of fossil energy sources (Germany, India, China), but also in the USA and Russia; the growth of energy consumption caused by the growth of the economy and the population is humped due to the introduction of energy-efficient technologies and due to an increase in the share of renewable energy; growth in the share of renewable sources in energy consumption and total factor productivity increases energy efficiency in terms of GDP per unit of energy used in Germany, India and Russia.

Electric vehicles were introduced in the year of 1908, where they have larger battery for power supply. Now- a- days the technique for charging e-bikes is done either by using grid supply or solar power. This paper says about charging circuit for batteries which uses both solar power and power from the grid to charge the electric vehicles. The charging with solar helps to reduce the emission from power grid. Ever-increasing demand for fuel supply, rising fuel prices, and increased environmental awareness among masses are paving the way for electric vehicles (EVs). Although, in recent years EV market has seen an exponential growth, one of the major challenges faced by this automotive/vehicular market. Now the Indian government had ordered to Indian Vehicle Association to launch the electric vehicles with in 2023. But the charging of electric Batteries has taken more time, which compare to fossil fuel and gas. To overcome this issue use of turbo charger, to reduce the charging time as well as self charging by solar during running time is proposed. The charger uses the source from EB grid and solar as well as at parking time. The results proves that proposed work have reduced the charging time of the lithium ion battery compared to the conventional charging technique and all under controlled temperature raise.

Object. The power industry of Russia is being developing with the use of its natural resources, advanced ideas, implementation of existing opportunities. So, the key task of the energy strategy of Russia till 2035 is the transfer from the commodity-heavy to the resource-innovative development of both the power industry and the economics of the country. All conditions have been created for its solution as of now – the power industry is expected to increase by 20-25% if demand for the hydrocarbon raw materials falls on the immediate horizon.In this juncture such branch as the power industry seems to be a crutial and sophisticated object of the research on the dynamics of economic systems infrastructural transformations. Anyway, its implementation in the field of the power industry involved quasi-market mechanisms of the preservation of existing ones and the building of new non-competitive powers with the use of such mechanisms as “adhesion contract” and “marginal price forming”.The work shows the inhibiting impact of these mechanisms on the economic system. The offer for its replacement to increase the pace of the power industry development and of the Russian economics substantiates.The research purpose is to substantiate the application of the consolidated balance-market model of economic systems for the analysis of the dynamics of the development of the technologically heterogenic branch, interacting with the other economic system, provided Leontief correlations. The power industry was selected as the studied one. Peculiarities of the reforming of power price rates, combining both market and regulating (quasi-market) mechanisms, were considered.Methods. The random balance-market model became the methodologic basis for mixed economic systems in the option of the self-consistent field of Leontief matrices. It make it possible to solve practical issues of the development of most important multi-agent branches in its interaction with the other economic system. In the work this model is applied in the quasitensor form for the evaluation of mixed mechanisms of the regulation of price rates in the power industry.Results. It was revealed that the common use of such mechanisms as “marginal price forming” and “adhesion contracts” fully suppresses the economic growth in all branches of economics. In order to find the way out was offered the consolidated random model of mixed economic systems in the quasitensor form. Its application will make it possible to obtain the new distribution of the capital by goods and agents with the better use of its technical advantages with such level of power rates.Conclusions. The possibility of the subtle analysis of the dynamics of the specialization and localization of agents was shown for the following development of distributed centralized energoinformational systems in the Russian Federation. It is expedient to use offered approach and developed algorithms of modeling for the evaluation of the accelerated economic growth of other key branches of the Russian economics.

During the last few years and in this context of constant innovation, several alternatives for internal combustion engines arose with the aim to find feasible options to fossil fuel consuming devices. As one may recall, the main alternative for internal combustion cars is without a doubt BEVs (battery electric vehicle). Those vehicles rely on electricity in order to function, storing the electricity in a battery pack and using it to feed a motor in order to give motion. However, some issues are still to solve in order to market them as appealing as internal combustion cars. Two of the most important issues to tackle are mileage range and charging time. On the other hand, fuel cell technology which began in the late sixties is beginning to take part in the automotive sector. This paper presents design evaluation and testing of 100 kW PEM fuel cell power pack for battery operated platform vehicle application developed to drive PMSM motor with requisite energy range that can be adapted by the power conditioning elements of the system under implementation to attain desired speed under Matlab/Simulink environment and the overall system dynamic performance was found to be coherent by analyzing basic operating parameters.

In recent years, Internet of Things (IOT) is being playing a major role in automation of Industries. Smart home systems are being employed in buildings to improve energy efficiency and reduce power wastage. Voice recognition is the current trend in automation. Regular methods of switching systems are difficult for paraplegic persons and blind persons since blind people can’t use the SMS method of automation. So voice recognition methods are preferred. Voice recognition systems involve calibration and programming to accept the user commands and operate the appliance. Amazon Echo dot, a smart speaker has an internally programmed Artificial Intelligence known as Alexa. It offers dual interaction and can be used to connect to Smart devices. To remedy the high cost of smart devices, we register a name in Alexa server as a smart device which comprises a Wi-Fi module and a relay. The Smart speaker and the Wi-Fi module form a single way communication which helps in controlling of appliance.
