“…Harmonic problems involve harmonic penetration from the external utility grid, current distortion caused by nonlinear and time‐varying loads, and various frequency harmonics and inter‐harmonics produced by DGs and ESS devices based on power electronics technology during their operation. These problems can even result in series resonance or parallel resonance of harmonics in severe cases …”

“…These problems can even result in series resonance or parallel resonance of harmonics in severe cases. [90][91][92][93][94][95][96][97] The voltage deviation primarily arises from the imbalance in reactive power between DGs and loads in the microgrid, specifically the reactive power demand fluctuations of loads in the microgrid, the output power fluctuations of uncontrollable DGs associated with wind, photovoltaic, and ocean energy, and the switchover from grid-connected operational mode to standalone operational mode, in which case the voltage deviation worsens. [95][96][97][98][99][100][101][102] The frequency deviation primarily arises from the imbalance in active power between DGs and loads.…”

Summary As a useful supplement and an effective utilization technique, microgrid technology has garnered considerable attention in the power industry. Despite this rapid development, microgrids continue to present technical challenges. A detailed systematic research overview of key microgrid technologies is presented from 5 aspects covering the typical structure, planning and design, operational control, protection technology, and power quality. In addition, potential beneficial prospects for these key technologies are discussed.
