dc.description.abstractStandalone low-voltage DC (LVDC) microgrids have emerged as potential alternatives in the context of effective rural electrification. The factors of reduction in conversion costs, paradigm shift in voltage levels of domestic loads made LVDC Microgrids more preferable. Being driven by intermittent renewable sources and dynamic loading, the voltage control is quite crucial and challenging to ensure a stable LVDC microgrid. Furthermore, delivering the control objectives becomes very difficult in the presence of sensor faults. In order to address this issue of sensor faults, this work proposes an Extended Luenberger Observer-based Active Sensor Fault-Tolerant Control (ELO-ASFTC) scheme. The proposed control scheme consists of the aspects of fault detection and isolation (FDI), and control reconfiguration. The proposed control scheme achieved the voltage tracking objective of the LVDC microgrid even under the presence of a faulty DC bus voltage sensor. The performance of the proposed scheme is observed in handling different sensor fault scenarios, loading conditions and irradiance changes. The effectiveness of the proposed control scheme is studied analytically, through the simulation studies in MATLAB, and hardware experimentation on the in house LVDC microgrid test bed. � 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.en_US
