In order to overcome the problem of power generation in distributed energy, microgrid(MG) emerges as an alternative scheme. Compared with ac microgrids, dc microgrids have advantages high system efficiency, good quality, low cost, and simple control. However, due complexity system, conventional droop control shows drawbacks current sharing accuracy. Therefore, improved primary methods enhance accuracy are systematically reviewed, such particle swarm optimization programming, probabilistic...
Due to the advantages of superior harmonics attenuation ability and reduced size, LCL filter has been widely adopted interface between inverter grid for improving quality injected currents. However, high-order characteristics various constraints complicate design. Moreover, stability internal current control loop individual is susceptible inherent -filter resonance peak. Meanwhile, overall system would be aggravated by external interactions weak as well among paralleled inverters. Both peak...
The large-scale application of wind power and photovoltaic solves the energy crisis alleviates environmental problems caused by use conventional energy. However, they are at risk being randomly tripped from network when faced to voltage sag severe fault events, which will lead a sudden reduction active output also complicates recovery process whole system. Moreover, it may aggravate failures outages, stimulates growing interest in analyzing low-voltage ride-through (LVRT) capabilities...
