Power sharing in parallel inverters with different types of loads

Unbalance mitigation strategies in microgrids

“…A multi-agent system-based hierarchical scheme is elaborated in [133]. A VI-based scheme is proposed in [134] and a LQR in [135] for reducing the effects of unbalance in the system. A two-level control scheme based on LBC using an unbalance compensator is proposed in [136] that ensures good performances under non-linear conditions as well.…”

“…The objective of the unbalance compensation or mitigation depends upon the conditions of the MG and the operating mode (islanded or grid‐connected). Unbalance mitigation in islanded MGs [18, 21, 22, 23, 25, 27–32, …”

Enhanced proportional power sharing strategy based on adaptive virtual impedance in low‐voltage networked microgrid

“…3b. In the d-q-axis, the virtual compensation voltage defined as V dvi and V qvi , the values are stated as [29,30]…”

Distributed coordination control for suppressing circulating current in parallel inverters of islanded microgrid

“…Unfortunately, it is not easy to get the accurate hardware parameters in practical paralleled inverters system; the parameters of the virtual impedance loop are difficult to be determined. Furthermore, with the development of networked control techniques, the third group is to use the low bandwidth communication in traditional droop control method which integrated local controllers to achieve load current sharing and dc bus voltage restoration [15][16][17][18]. Moreover, this naturally leads to the next control level, termed secondary control to remove the aforementioned deviations generated in primary control level.…”
