Editorial: Grid Connection of Converters in Renewable Applications [PDF]

open access: yesFrontiers in Energy Research, 2021
Energy generated from renewable sources is fed into the grid by means of electronic power converters. These can be supervised at system (grid) level to coordinate all productions points together with storages and loads. Regulations impose power supply quality requirements regarding harmonics, grid fault response and low voltage ride through (LVRT). The

A Universal Controller for Grid-Connected Voltage-Source Converters [PDF]

open access: yesIEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
Power-synchronization control (PSC) and vector current control (VCC), the latter including cascaded outer loops, are, respectively, considered to be grid-forming and grid-following schemes. They have significant structural differences. Despite that, it is here shown that the two schemes can be unified by making a series of minor modifications to PSC ...
