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.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125886301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130133732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116010901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126602383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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).
