In photovoltaic (PV) power generation systems, the parasitic capacitor is introduced between PV panels and the grounds, which inevitably leads to the leakage current. The leakage current causes electromagnetic interference, distorts the output currents quality. . If transformerless inverters are used, so-called displacement currents can occur which are capable of tripping the residual current monitoring of the inverter or even that of the feed-in line. In the former case, this causes the inverter to temporarily disconnect from the utility grid, after which. . Abstract: This work presents a generalised integrator-based control algorithm for power quality (PQ) amelioration of the grid in the presence of non-linear load enabling leakage current suppression feature.
