In this paper, ozone generation using non-thermal plasma is discussed, in the context of its use for diesel engine exhaust treatment. To achieve maximum oxidation of nitric oxide and other pollutants in the exhaust for varying engine loads, the ozone generation needs to be varied accordingly. As the parameters controlling ozone generation can have multiple combinations, finding the right set of parameters to achieve a specific ozone concentration requires several experimental trials. In such cases, the availability of a model that accurately predicts the concentration of ozone for a given set of parameters reduces the experimental burden of conducting such trials. With this objective, two mathematical models, Response Surface Methodology and Fuzzy Logic Model, have been explored as possible techniques for prediction of ozone concentration.","PeriodicalId":306418,"journal":{"name":"2020 IEEE International Conference on Power Systems Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130321214","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}

Small disturbances such as sudden load change which occurs during normal operation causes transient oscillations, which deteriorate the performance of the system. The paper presents the modelling of voltage source inverter based distributed generator which consists of power controller, voltage controller, current controller and LC filter with coupling inductor. The linearized model of the microgrid is obtained to analyse the small signal stability of the system using eigenvalue analysis. The eigenvalue analysis of the system determines dominant parameters subjected to system stability and their optimum value using root locus method. A gravitational search algorithm is implemented to evaluate the optimum value of dominant parameters in order to enhance system dynamic performance. The proposed algorithm is validated on a two inverter based test system under various operating conditions including change of mode of operation, three phase fault and load changes during islanded mode of operation. Simulation results show the effectiveness of the proposed algorithm which results in enhanced dynamic performance of the system with reduced overshoot and settling time.","PeriodicalId":306418,"journal":{"name":"2020 IEEE International Conference on Power Systems Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121008939","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 measures taken to mitigate any drastic increase in consumption patterns relate to energy efficiency programmes as well as behavioral changes. However, various surveys have concluded that consumers have little or no understanding of energy consumption units and thus they are not engaged with their energy use. The installation of household smart energy meters could provide one solution for the energy visibility of households. Unfortunately, these devices are very expensive and unaffordable for a large majority of families. With the emergence of low-cost microcontrollers and sensors, IoT-based smart meters can be implemented at a fraction of the cost of commercial ones, with most of their functionalities. In this paper, we present the design and implementation of a complete control system for household energy management, using two technologies- Wi-Fi for indoor use, and LoRaWAN for long distance transmission and outdoor use. An energy meter prototype was first built, and in-depth tests were carried out for two specific appliances, namely a table fan, which operates in the same state for long hours, and on the other hand, a washing machine, which continually changes states. Results are very conclusive and provide a high level of visibility on appliance energy consumption. It is believed that with access to such a meaningful level of data, consumer behaviour will change positively and their engagement will become more prominent for a reduction of energy consumption in the household sector.","PeriodicalId":306418,"journal":{"name":"2020 IEEE International Conference on Power Systems Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124495293","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}

A healthy power system only can cope with the accelerated power demand scenario without compromising power quality. High voltage power transformers are significant and crucial equipment in an electrical system, subjected to various internal & external operating stresses. Failure of such utility in the electrical system creates unwanted power interruptions, which can even collapse the economy of a country. Insulation degradation is reported as a major cause of failure of these apparatus where partial discharge being the most significant signature and an indication of insulation deterioration, plays a vital role in causing the overall insulation degradation of the system as well. Therefore, condition monitoring of partial discharges in high voltage power transformer is essential to recognize early insulation collapse so that it can suggest proper corrective action to elevate system reliability and customer satisfaction. In this paper, condition monitoring through partial discharge detection has been carried out on different oil samples of a model transformer with the acoustic method by using temperature compensated Polyimide coated fiber Bragg grating-based acoustic sensor. The sensor is placed inside the model transformer, and then the measured partial discharge values are compared with the conventional electrical detection method. The proposed sensor provides a comparable detection capability over the conventional electrical detection method, which establishes fiber Bragg grating-based acoustic detection method as a superior alternative for online condition monitoring of high voltage power apparatus.","PeriodicalId":306418,"journal":{"name":"2020 IEEE International Conference on Power Systems Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122689787","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}

EVs depend on the availability of efficient energy storage devices for propulsion. They can also be coupled with an Internal Combustion Engine (ICE), referred to as Hybrid Electric Vehicles (HEVs) which provide improved range and power. Lithium-ion batteries (LIBs) are currently being considered as a potential energy storage device for the propulsion of the EVs due to their numerous advantages such as high energy density and power density, compact size and good cyclability. The rapid commercialization of EVs and HEVs has led to a rapidly increasing demand for high-power and high-energy-density batteries. In this regard, a standard method for testing of performance of lithium-ion batteries is indispensable for securing a basic level of performance and in collecting essential data for the design of vehicle systems and battery packs. This review discusses various factors which are considered while selecting LIBs for EV applications, various national and international standards currently available and adopted for performance testing of LIBs used in EVs and HEVs. The review also aims to provide a brief overview of the various tests described in these standards.","PeriodicalId":306418,"journal":{"name":"2020 IEEE International Conference on Power Systems Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123480419","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}
