Enhancing loading limitations in PV systems

This paper discusses the loading limitations in PV systems resulting from switching the power electronic interfaces and transients associated with large loads. These conditions derate the power generation capability of the PV system. We propose some methods to enhance the loadability of these systems under both steady state and dynamic operations. A PV system for home application purposes, with a rated power of 280 W was designed and built. The proposed enhancements were applied to the experimental setup and the obtained results verified the effectiveness of the proposed methods.
