دانلود Sensitivity Analysis for the Power Quality Indices of Standalone PV Systems

Abstract

Standalone  PV  systems  is  a  key  technology  for  the increase of renewable energy sources share in electricity production worldwide. The power quality of those systems plays a fundamental role in avoiding volatile power supply. This calls for a concrete design in order to meet power quality specifications. In this context, a methodology has been developed in a previous work, in order to set the values of the parameters that optimize the power quality  indices  of  the  system.  In  the  current  work,  an  extensive sensitivity  analysis  is  performed  regarding  the  influence  of  the optimized  parameters  variation  on  the  power  quality  indices. Throughout the outcomes of the sensitivity analysis a more insightful view of the system performance under the deviations of system  parameters  is  revealed,  which  in  combination  with  the aforementioned optimal design strategy becomes an essential tool that ensures high power quality level. The theoretical outcomes are validated by experimental results, highlighting the effectiveness of the proposed design strategy.
