One millions of PHEVs are estimated to be in the USA market by 2015. Uncoordinated PHEV charging will cause significant impacts to the power grid; i.e. lines and transformers overload and voltage drops. Appropriate charging methods should be used to minimize the impacts of PHEV charging activities and at the same time minimize daily charging cost. This paper presents methods used to charge the PHEV battery namely price-based charging, load-based charging and SOC-based charging. Evolutionary programming (EP) is then used to optimize the charging rate and SOC thus minimizing the charging cost. Charging cost is calculated based on real time electricity price i.e. Locational Marginal Price (LMP). Since the data pattern for LMP is similar throughout the week, the day-ahead price model is used to calculate charging cost. Results from the study indicated that charging strategies used produces different impacts to the grid. Moreover charging cost may vary from one method to another. Optimization of charging rate and SOC hence minimized charging cost is done by EP.","PeriodicalId":112576,"journal":{"name":"2014 IEEE 8th International Power Engineering and Optimization Conference (PEOCO2014)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122224650","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}

Additionally, interruptions of power transformer have a significant economic Effects on the Performance of an electrical network. For this reason, the safe and reliable Performance relate directly to the Security and stability of power system. This paper studies the growth of power losses and Derating of Distribution transformer, working under unbalance voltage and unbalanced load conditions. In this paper, computer-based simulation utilizing the two and three dimensional finite element methods (3-D and 2_D FEM) are exploited as a tool for visualizing magnetic fields of distribution transformers. Finite Element Method (FEM) is one among popular numerical methods that is able to handle problem complexity in various forms. The performance of the transformer when the load and supply are balanced compared to the case in which voltage or load is unbalanced indicates that the unbalanced load only causes the copper loss to increase, while the unbalanced voltage not only increases copper loss but also adds to the core loss. The indices of voltage unbalance factor (VUF) are used in this paper to evaluate the unbalance propagation. This process enables the software to simulate and analyze different electromagnetic parameters such as magnetic flux lines, flux density, losses, and etc, under different input sources with high accuracy.","PeriodicalId":112576,"journal":{"name":"2014 IEEE 8th International Power Engineering and Optimization Conference (PEOCO2014)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124561941","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}
