Control Considerations for Photovoltaic Powered Water Pumping Systems

Abstract

Overall efficiency of pv water pumping systems depends on system topology, sub-component efficiency, the proper matching of these sub-components and the system control configuration. The benefit of optimal control methods for pv water pumping systems is explored in this paper. Two pumping experiments are described here. The first is located in Arizona-USA and the second in Attica-Greece. Analytic results are compared to experimental data. Issues related to, computer simulation of pv water pumping systems, pumping hardware and borehole modeling and parameter identifi-cation, optimal system topologies for specific environments, analytic techniques for pv pumping system control optimization, pumping system hardware seleCtion and matching, are addressed. 1.
