I designed inverter, that was based on inverter stage of this kit: https://www.ti.com/tool/TMDSSOLARPEXPKIT . I successfully implemented working in islanded mode as well as grd-synchronization mode. Now I want to work multiple inverters in parallel mode. To work in grid synchronization I use the PLL. I was thinking that maybe I can use the same PLL to run in parallel operation, but it is not possible. I probably need some load-sharing or droop control to implement. Anyone has experience with it? Any software? I was reading some IEEE papers, but mostly they are presented typically mathematical approach this is not easy for me to translate it to C language.
