So far, researches about allocation of distributed generation sources would have been done in completely balanced systems. In this paper optimized allocation of these sources in unbalanced distributed system in different consumed loads and unsymmetrical in transmission lines structure has been discussed. Since the voltage unbalance is one of current problems in distribution networks, decreasing of voltage unbalance factor (VUF) in distribution network in order to increase quality of power delivery to customers is one of the aims in optimized allocation of distributed generations in this study. Introducing multi-objective function for allocation of distributed generation sources, in order to minimize voltage unbalance factor and real power loss, improving of voltage profile and increasing of economic profit, the concepts of multiobjective optimizing (PARETO) in studied networks is used. With due attention to necessity of power flow studies in studied unbalanced distribution systems, this study using Cyme-Dist software and optimizing process, with connection between the mentioned software and MATLAB software is done. In continuation, allocation of distributed generation in IEEE standard 13 bus network, in three different load levels and using NSGA-II algorithm has been studied. Results show that proper placement of distributed generation sources in unbalanced distribution systems; can decrease both losses and amount of voltage unbalance. Also in this study shown that, appropriate placing of distributed generation sources, provides considerable profit to distribution companies.","PeriodicalId":179631,"journal":{"name":"18th Electric Power Distribution Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123543279","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}

While OEMs ceased the R&D-operations for this subject already, SMEs still focus on innovative technologies for car traction. As these companies cannot subsidize their electric vehicles and use cost efficient conversion design derivatives, a positive Return on Engineering is necessary even for small production volumes of purpose designed cars. The electrification of the drive train is a 'task of the century' and the substitution of combustion engines becomes inevitable in medium terms. Uncertain market trends create insecurity for producing companies regarding investments in equipment capacity. The production system elaborated in this paper presents an approach to solve three main issues of the electric traction engine production: the assessment of a specific engine technology, the definition of the technology chain for production and the use of scalable manufacturing concepts as well as intelligent automation to face changing market conditions. This approach is not only applicable to the production of an electric traction engine, but to vehicle manufacturing in general.","PeriodicalId":179631,"journal":{"name":"18th Electric Power Distribution Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120939971","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}
