Journal ArticleDOI
High-accuracy maximum power point estimation for photovoltaic arrays
TL;DR: Based on the p–n junction semiconductor theory, a prediction method for directly estimating the MPP for power tracking in PV arrays is developed with a new and simple approach with a low calculation burden that takes the resistance effect of the solar cells into consideration.
Journal ArticleDOI
Analysis of the junction temperature and thermal characteristics of photovoltaic modules under various operation conditions
TL;DR: In this paper, the junction temperature of the photovoltaic (PV) modules is directly determined based on the p-n junction semiconductor theory, and the proposed method is a new and simple approach with a low calculation burden.
Journal ArticleDOI

Joe-Air Jiang,Yu-Li Su,Jyh-Cherng Shieh,Kun-Chang Kuo,Tzu-Shiang Lin,Ta-Te Lin,Wei Fang,Jui-Jen Chou,Jen-Cheng Wang +8 more
TL;DR: In this article, the authors integrated the previously proposed direct-prediction MPP method with a perturbation and observation (P&O) method to develop a new hybrid MPPT method, which is further utilized in the PV inverters in a PV system installed on the roof of a closed plant factory at National Taiwan University.
Journal ArticleDOI
A novel method for the determination of dynamic resistance for photovoltaic modules
Jen-Cheng Wang,Jyh-Cherng Shieh,Yu-Li Su,Kun-Chang Kuo,Yen-Wei Chang,Yu-Ting Liang,Jui-Jen Chou,K.-C. Liao,Joe-Air Jiang +8 more
TL;DR: In this paper, the authors proposed a method to directly determine the dynamic resistance of the PV modules from an irradiated current-voltage characteristic curve, using a combination of finite series-and shunt-connected resistance.
Journal ArticleDOI
An Interval Type-2 Fuzzy Logic System for Stock Index Forecasting Based on Fuzzy Time Series and a Fuzzy Logical Relationship Map
TL;DR: The proposed interval type-2 fuzzy logic system for stock index forecasting based on a fuzzy time series and a fuzzy logical relationship map (FLRM) is applied to data from the Taiwan Stock Exchange Capitalization Weighted Stock Index, the Dow Jones Industrial Average, and the National Association of Securities Dealers Automated Quotation.
