New numerical sizing approach of a standalone photovoltaic power at Ngoundiane, Senegal

A new sizing method based on a numerical approach using the average meteorological data and the load demand of the Ngoundiane site along with both concepts of ALPSP and TLCC is treated in this study. The intuitive method, has been first applied to delimit the PV capacity range. Thereafter, the incoming new approach that we propose, consists in elaborating a simple algorithm based on a numerical determinist sizing approach by adapting the available average data to the mathematical equations used in numerical approach. The results show that for a same value of the total capacity of PV array, estimated to 177.5 kWp, the proposed numerical sizing method decreases the storage system capacity to 75% and the TLCC to 65% compared to the intuitive method.
