Abstract

The quality of load matching in a photovoltaic power system (PVPS) determines the system performance and the degree or the solar cells utilization. In a good matched system, the operation of the load-line is close to the maximum power-line of the solar cell (SCA) generator. This paper presents a new methodology for modeling a stand alone PVPS using the Graph Theoretic Modeling (GTM) Approach. The studied system composed of a directly connected SCA generator-dc motor supplying different load types. A computer program (written in MATLAB 6) has been developed to model the studied system. The computer program is then applied to nine case studies for different types of dc-motors and various mechanical loads. A comparison between these cases is introduced to indicate the appropriate motor type for each load.
