摘要: Abstract This paper presents a novel algorithm for online identification of the Thevenin equivalent parameters in ac three–phase power grids inductive nature. One unique property is to ensure convergence estimated within finite time, provided that weak excitation condition—necessary identifying offline parameters—is verified. After reduces standard recursive least–squares track possible changes parameters. Moreover, requires neither circuit nor active manipulation circuit. The proposed evaluated via computer simulation and experimental prototyping case study consisting inverter connected mains source an Results show method able successfully identify
