Authors: Dhawale Dinesh , Kamboj Vikram Kumar
Published: August 2020

Electric vehicles are getting popularity as these are eco-friendly and could be a part of power sector in the future. Electric Vehicles are the smart hybrid vehicles, which stores electric power during their operation, which could be stored in storage cells. These electric vehicles may be plug-in electric vehicles or battery operated electric vehicles. The concept of aggregators may be utilized, wherein the stored energy in vehicles could be supplied to grid during parking hours .This also facilitate the consumers to sale power during the high power demand and purchase power during low power demand. Thus, a bi-directional flow of power could be possible either from vehicle to grid or vice-versa. A large penetration of electric vehicles could result in increase in power demand which could be compensated by proper coordinated unit commitment and optimization techniques. The increasing load on grid by the impact of demand and trends in small generating units which require proper selection of number of generating units to put in line and other units in off condition calls for the concept of unit commitment. It is the selection of more efficient units to be in service and shutting down the other unit while maintaining all the other constraint constant. This would result in effective power flow in an economic manner, simultaneously maintaining the adequacy and reliability of the system. The proposed research represents the scope of intelligence algorithm for unit commitment problem with effective solution of vehicle to grid operations along with sustainable energy for realistic power system.

Authors: Chavan Gayatri , S Sridhar.
Published: August 2020

Over the past decade, research efforts have been made to decrease the number of power electronic devices needed in multi-motor drive systems in order to condense the overall complication and cost of the drive. This paper proposes speed control for a dual three-phase induction motor system driven by five-leg voltage source inverter (FL-VSI) which is used in industrial manufacturing processes. Industrial applications frequently need a number of variable speed electric drives. This technique uses five-leg inverter instead of using conventional two three phase inverters. In the majority of cases, these multi-motor drive systems need independent control of individual motors. It is shown recently that it is possible to separately control two three-phase induction machines supplied through a five-leg voltage source inverter, with one inverter leg being common to both machines. The entire performance of the speed control for the five leg voltage source inverter fed dual-motor drive system is investigated using MATLAB/SIMULINK software.

In the digital era, we are greatly dependent on the popular applications of the Location Based Services (LBS) in our day-to-day activities. The smart phone comes with a variety of applications which acquire the user location and build up user profile like the user activities, hobbies, places of visit, food orders etc. Such sensitive information in the LBS server can pose privacy risk for the user. To safe guard the user from such threat we propose a smart privacy protection technique in this paper that can conceal the user location when using the location based services. We adopt the generation of dummy locations to obfuscate the user original location from the LBS server. The server generates the result set for the dummy user locations. In this work we try to optimize the things at server as well as user ends with two objectives. The first goal is to work towards identifying the overlap in result sets and generate unique and reduced result set with which the communication load on the network can be reduced. The second goal is to prioritize the result set by Queuing model for the result set through which waiting time of the customer can be minimized. We have also illustrated that this model show good performance in terms of the reduced communication load through experimental results.

Published: August 2020

The Security constraints unit commitment (SCUC) is a powerful scheduling technique used in power markets for daily planning. SCUC is a framework that combines two common algorithms in the electricity industry: Unit Commitment (UC) and Economic Dispatch (ED), while adding a new dimension – Security. Load demand is changing continuously due to variation of load of industrial, residential and commercial sectors. Thus, it is very important to decide which generating unit should be kept on and how much power should be dispatched so that time varying load demand can be meet on Hourly basis and there should be no scope of occurrence of loss of load hour (LOLH). In the proposed research, the recently developed hybrid meta-heuristics search algorithm i.e. GWO-RES has been applied to solve the security constrained Unit Commitment and dispatch problem of Electric power system. The efficiency of the proposed hybrid algorithm has been tested for standard IEEE-14 Bus, 30-Bus and 56-bus system and it has been experimentally found that GWO-RES performs much better than hybrid GWO-PS and GWO-RS algorithm.

Curing of concrete is maintaining satisfactory moisture content in concrete during its early stages in order to develop the desired properties. « However good curing is not always practical in many cases, therefore the need to develop self-curing agents attracted several researchers ». « The concept of several self-curing agents is to reduce water evaporation from concrete and hence increase the water retention capacity of concrete compared to conventional concrete, the use of self-curing agent is very important from the point view that water resources are getting valuable every day ». This project summarizes various aspects of self-curing of concrete which can be of valuable assistance in adopting good construction practices at site. M25 grade concrete cube specimens prepared based on the standards and availability of materials without and with 30% of flyash and quarry dust replaced as cement and fine aggregate and cubes cured by covering them with a external self-curing compound BONDIT CURE WB, air dried and normal water. These specimens are then tested after 7,14 and 28 days to obtain the compressive strength in three different conditions. The compressive strength of concrete cubes is calculated and compressive strength of self-curing concrete is compared with the different conditions. At the end of curing period of 7,14 and 28 days the amount of water retained in self cured concrete cubes is calculated and compared with the air dried cubes. Water absorption test is conducted on air dried concrete and self cured concrete cubes and the amount of water is absorbed is calculate and compared.

The goal of the study is to determine the fundamental intention of the educational project implementation in the Masters’ program for training business lawyers for the digital economy. The main methods used are the analysis method and the sociological method. The main result of the study is that the main goal of educational projects for training business lawyers is the development of a set of regulatory competences. The conclusions are that the competence-based approach is an objective trend in modern education, largely supported by students. A number of factors have been identified that impede the formation of basic lawyers’ competences for students in the digital economy, based on the sociological study. Due to the lack of reference to “digital” competences in federal state educational standards, it is advisable to introduce additional competences in the local acts of the educational organization that take into account the need for lawyers to use information and telecommunication technologies.

The authors’ goal has been to show the need to improve both the general level of education of self-employed citizens, and, mainly, the actual level of specialized competencies. The modern world does not tolerate an unskilled approach in any business. Therefore, special education for self-employed citizens is their internal need that has direct impact on their well-being and relevance in the modern labor market. Real digital technologies aim at improving comfort for self-employed citizens while realizing their need in specialized education. For efficient forecasting, the inductive analysis method has been chosen. This is when the current and previous situations in the self-employed market are examined, then the main factors of the market development are revealed, and the main reasons for the formalization of self-employment are considered. Based on this, the prospects for increasing the self-employed citizens’ groups as consumers of general and specialized education are defined. Sociological instruments of this study include expert surveys, in-depth interviews, analysis of Internet publications of central print media, and content analysis.

The main results of the study are as follows:

• There is an exponential increase in the number of registered self-employed citizens – consumers of specialized education in the medium term.

• Self-employed citizens specializing in such areas as IT, tutoring, online courses, beauty industry may become the most promising in the market of additional specialized education.

• Self-employed citizens aged 35 – 45 are the most promising in the market of general education, mainly in pension legislation.

• The accessibility of self-employed citizens as potential consumers of educational services can be ensured mainly through their official registration. The official registration of self-employed citizens can be stimulated by a) more favorable tax regimes for self-employed citizens, b) a simplified registration procedure, and c) the introduction of harsh administrative penalties for evading the registration.
