Optimum matching of direct-coupled electromechanical loads to a photovoltaic generator
The objective of the paper is to present a general mathematical formulation for matching electromechanical loads connected to a photovoltaic array. An optimization method is then used to solve the matching problem with the objective of maximizing the gross mechanical energy. The analysis is extended to obtain the sizing of the array and the battery in the direct-coupled system. Results show that optimum matching can be achieved by carefully selecting the PV array rated parameters with respect to the load parameters. The rated power of the array is twice that of the load. The field constant that maximizes the gross mechanical energy can be obtained given the parameters of the load and the array temperature. The separately excited motor offers higher matching performance compared to the series motor. The rotodynamic load offers better matching compared to the viscous friction load.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
