The accurate prediction of PHEVs-induced loads needs a comprehensive study of PHEV characteristics. The authors divide the PHEV characteristics into two categories: driving pattern and vehicle parameters. Due to the stochastic nature of vehicle arrival time, departure time and daily mileage, probabilistic methods are used to model the driving pattern by many researchers. But the three elements of driving pattern are correlated which each other, making the probability density functions (PDFs) based probabilistic methods inaccurate. Based on the National Household Travel Survey (NHTS) database, the authors proposed a fuzzy logic based stochastic model to study the relationship between the three elements of driving pattern. Moreover, the authors proposed a load profile modeling framework (LPMF) for PHEVs to synthesize both the characteristics of driving pattern and vehicle parameters into a load profile prediction system. Finally, the proposed LPMF of PHEVs is tested in a residential distribution grid, and the results are compared with deterministic and probabilistic models of PHEVs.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129892086","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}

This paper presents the development of a new NOCT applicable for tropical regions and it is called as the tropical field operation cell temperature (tFOCT). A new equation for calculating cell temperature is developed by determining a new value for the tFOCT and its measuring conditions, which are solar radiation, ambient temperature, and wind speed. These conclusions are based on the condition of the tropical weather environment as a unique approach for field value adaptation. Site monitoring and analysis of the installed system were performed for 10 consecutive months at the Universiti Kebangsaan Malaysia. The results show that the suitable weather conditions for measuring tFOCT are irradiance of 954 W/m2, ambient temperature of 330 °C, and wind speed of 1.5 m/s. The proposed correlation model between ambient temperature and solar radiation and the cell temperature is useful for PV manufacturers who intend to install their PV products in tropical countries.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125473057","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 PV system is interfaced with the BESS at the DC link to provide reserve power. These two different integrated solutions can be compared with regards to the number of power stages, efficiency, storage system flexibility, and control complexity. A single power conversion system named Reconfigurable Solar Converter (RSC) presents more flexibility, less complexity, and multi-mode capability depending on system requirement, and results in a more efficient and economical system compared with a current indirect PV/battery system with two stages of power conversion units. There are various approaches to share the load when microgrids are islanded or disconnected from the main grid. In the islanded mode, a distributed generator (DG) like a diesel generator can enhance the reliability of the power supply and regulate the frequency and voltage within the microgrid. Different operation modes for both topologies such as PV to grid, PV plus battery to the grid, battery to the grid (DC to AC) and PV to battery (DC to DC) are simulated on a microgrid testbed, verifying the applicability of the two architectures in microgrids.","PeriodicalId":161074,"journal":{"name":"2014 IEEE PES T&D Conference and Exposition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125608731","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}
