Distributed generation network design considering ground capacitive couplings

Distributed Generation (DG) systems using power-electronics-based grid interfaces magnify the problem of ground capacitive couplings in modern distribution networks. The application of simplified models to DG installations neglects the current distortion, potential rise, and losses in the system as consequence of the capacitive coupling within the installation. These capacitive couplings represent a leakage impedance loop for the capacitive currents imposed by the high-frequency switching of power converters.
