Analysis and Mitigation of Harmonic Resonances in Multi–Parallel Grid–Connected Inverters: A Review

With the move towards decarbonization of energy system and increased use renewable generation, number power electronics converter interfaced resources connecting to grid is growing. These converters have fast dynamics determined by control algorithms, which leads significant changes in impedance characteristics system. Based on practical experience, concerns grown about interactions between can give rise instability a with multiple grid–connected inverters operating parallel. This paper reviews recent work related understanding, modeling mitigation such interactions. The basic concepts underpin are explained discussed from an stability perspective. illustrated means example case low voltage distribution In years, several approaches been proposed prevent or mitigate effects these most works categorized comprehensively reviewed.
