Due to limited reserves and 100% inverter-based resources in an islanded residential microgrid (IRM), largefrequency oscillations may arise during load/generation fluctuations. As an independent grid-forming unit, a battery energy storage system (BESS) can participate in load-frequency control (LFC) to achieve environment-friendly and reliable supp...

Battery energy storage system (BESS), as grid forming unit, can quickly regulate voltage and frequency for a 100% inverter-based islanded low voltage microgrid. However, due to some inherent characteristics of this network, such as: (a) coupling among voltage and frequency dynamics, (b) dynamics of dc source, and (c) timescale coupling among conver...

A microgrid may be subjected to various unexpected events, such as sudden tripping of a generator/load, line outages due to faults, sudden switching of large capacitor banks, etc. Detection and classification of events play an essential role in the reliable operation, control, and restoration of microgrids. Due to low observability in microgrids, a...

A battery energy storage system (BESS) can play a critical role in regulating system frequency and voltage in an islanded microgrid. A $\mu$ -synthesis-based robust control has been proposed for dc link voltage regulation of BESS for achieving frequency regulation and voltage quality enhancement of islanded microgrid. Variation in the operating c...

Detection of shorted DC faults and high-resistance faults on ring type low-voltage DC (LVDC) micro-grids imposes an elusive challenge. This research work proposes an efficient and reliable protection scheme for DC system in order to boost up LVDC system adoption on large scale, despite lack of proper standards and mature experience in DC system pro...
