EXPERIMENTAL AND SIMULATION RESEARCH ON CONFIGURATION OPTIMIZATION OF PHOTOVOLTAI PUMPING SYSTEM

This paper focus on the assessment of how much insolation conditions, system configurations influence the sys-tem performance and economic performance of photovoltaic (PV) pumping system. Carrying out experiments, establishing mathematical models of system components, the system efficiency and operation effects of PV pumping system were simu-lated with Matlab/Simulink Tools. Some conclusions about the influences of pumping head, insolation intensity and distri-bution, and the capacity of PV array to the efficiency and economic performance of PV pumping system, and system con-figuration optimizing, system running cost decreasing, and system economic performance improving were deduced, and the selection principles of pump types and the capacity of PV array for optimizing system cost were concluded.
