Optimum load matching in direct-coupled photovoltaic power systems - application to resistive loads
Khouzam, Kamel Y. (1990) Optimum load matching in direct-coupled photovoltaic power systems - application to resistive loads. IEEE Transactions on Energy Conversion, 5(2), pp. 265-271.
In this paper the load matching factor is used as a measure for the quality of load matching to the photovoltaic (PV) array. An optimization approach is used to solve the load matching problem with the objective of maximizing the load matching factor, and consequently the PV output energy. Thig approach is then applied to resistive loads (with and without an internal emf) connected to the array.
Results show that optimum matching can be achieved by carefully selecting the array parameters with respect to the load parameters. The temperature of the array has little effect on the optimum matching factor. However, the optimum matching parameters are greatly affected by the array temperature. A maximum power tracker may not be needed if optimum or near optimum matching is achieved. A battery of selected parameters can be included if the load characteristic results in poor matching performance.
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.
