A brief review of this topic is provided. The study states that the electric power industry should be regarded as a combination of four sub-industries when regulation, market design, and industrial organization problems are discussed. These four sub-industries are generation, transmission, distribution, and sales because of different regulations applied to these businesses. The main trends in the retail price index and some other indexes in the four sub-industries are observed from 2009 to 2018. The trends in electricity consumption and generation structure are discussed as essential components of economic processes in the industry. The findings suggest that the four sub-industries make different contributions to the overall growth of the electricity supply costs for end consumers. Most growth was determined by regulated government-granted monopolies in network businesses (transmission and distribution companies). The sales business is represented in the research by suppliers of last resort.","PeriodicalId":171218,"journal":{"name":"Energy Systems Research","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122362700","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 significant factor of such an impact is the considerable intensities of electromagnetic field (EMF) generated by such facilities. In the context of power industry digitalization, the development of methods and tools for EMF digital simulation is needed to ensure the electromagnetic safety of the service personnel. Computer models designed to adequately determine the EMF generated by overhead power lines (OPL) can be implemented based on the methods and tools created to determine operating parameters of electric power systems in phase coordinates developed at Irkutsk State Transport University. The technique of electromagnetic safety analysis is implemented based on the proposed approach and has the following features: a systems approach, which is the possibility of simulating electromagnetic fields in terms of properties and characteristics of a complex electric power system; versatility, which allows simulating power lines and traction networks of various designs; appropriateness to the environment achieved by considering the profile of the underlying surface, underground utilities, and artificial structures of rail transport, such as galleries, bridges, and tunnels; comprehensiveness, which is provided by combining the computation of operating parameters and the determination of EMF intensities. The paper describes methods and algorithms developed to determine the intensities of electromagnetic fields generated by multi-conductor power lines at fundamental and higher harmonics frequencies. A technique for the EMF determination at the points of OPL orthogonal crossing is also presented.","PeriodicalId":171218,"journal":{"name":"Energy Systems Research","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130421822","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}

Space vector pulse width modulation (SVPWM) is a widespread digital compute-intensive control technique used in the control of power converters. This study aims to overcome the large number of calculations needed by the SVPWM algorithm, which limits its implementation in many advanced industrial applications. This paper presents a low-cost software implemented simplified SVPWM technique. The proposed strategy generates the inverter switching times in a straightforward manner with no need for complicated and time-consuming sector identification and look-up switching tables. A simulation study has been done using MATLAB/SIMULINK environment for the three-phase voltage source converter (VSC). The results in terms of total harmonic distortion (THD) in the converter line voltage are compared for the proposed technique, conventional SVPWM, and space pulse width modulation (SPWM). The execution time is reduced considerably with a slight increase in the value of THD and about 14.4 percent DC-link voltage utilization over the SPWM.","PeriodicalId":171218,"journal":{"name":"Energy Systems Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131182532","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 concept of low-carbon cities is extensively discussed nowadays. It aims to reduce greenhouse gas emissions through integrated mechanisms and measures, which comply with socio-economic development and city management. Since a considerable part of the population lives in cities, the utmost goal of the study is to analyze the situation with emissions of the main greenhouse gas, i.e., carbon dioxide, in the urban environment. The major sources of carbon dioxide emissions are stationary energy facilities of different capacities burning fuel. The paper considers the city of Irkutsk as an example of the populated area included in the study on low carbon cities under the auspices of the Social and Economic Commission for Asia and the Pacific of the UN - UNESCAP. The first stage of the studies involved assessing the current carbon dioxide emissions from energy facilities of the city through the calculation of carbon dioxide emissions from boiler houses and the city cogeneration plant for 1990. The findings revealed the potential of reducing carbon dioxide emissions from energy facilities in Irkutsk. The paper suggests the basic directions and measures to mitigate greenhouse gas emissions from the urban energy facilities.","PeriodicalId":171218,"journal":{"name":"Energy Systems Research","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115279176","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}
