-The Jeju Special Self-Government Provincial Government has made the plan penetrating gradually electric vehicles(EVs) in the Jeju Special Self-Government Province(Jejudo). However the effects of EVs penetration on the electrical grid of the Jejudo is not reported. In this paper the yearly electric energy consumed by the EVs was calculated and the effects of the EV penetration on the peak power of the grid were analyzed in the Jejudo for the future 10 years, and we hope that our study results will help the governors realize the EVs penetration plan in the Jejudo . The calculation results show that the rate of the electric energy used by the EVs will become to 2.9% at its maximum at the 2017 year when the penetration rate of EVs in passenger cars becomes 10%, and the rate of the electric energy consumed by the EVs will become to 9.4% at its maximum at the 2020 year when the penetration rate of EVs in passenger cars becomes 30%. The concepts of smart-charging capacity and 100%-valley-filling charging capacity of the grid were defined and calculated for the Jeju Grid, and the grid was analyzed to have the sufficient EV charging capacity until the 2022 year.
-An 1 MW PV plant constructed at the Ara campus of Jeju National University in May 2012, which was the biggest roof-top PV plant in Korea and the biggest PV plant in Jeju Island at the time. In this paper the generation characteristics of the plant was analyzed on the basis of the data obtained during 2 years.The amount of electrical energy generated by the plant in July was less than those by the PV plants of the other regions except Jeju Island in Korea, which might be due to the long rainy season started in June earlier than the other regions. But those generated by the plant during summer season was more than those during autumn, which was different trend from the other regions in Korea. And the yearly capacity factor of the pant was 12.7% which is low relatively in Korea.The loss of the transformer in the plant, as expected, was shown to increase according to increasing the electrical energy generated by the plant. Summer's transformer loss was greater than spring's one in spite of summer's generated electrical energy less than spring's one, which tells that the transformer have the need to strengthen its cooling in summer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
