I Ask to change this title of my paper '' Influencing length of the power line on grid-connected photovoltaic system '' by right title '' Influencing factor analysis of the short circuit ratioon grid-connected photovoltaic systems''
you can use ''line length influencing in grid connected PV system'' or ''Analysis of the short circuit ratio influencing in grid connected pv system'' or ''Impact of Short-Circuit Ratio in grid connected pv systems''
