This article revises and updates the electromagnetic compatibility (EMC) challenges commonly encountered in utility-scale grid-connected photovoltaic (PV) systems in light of modern trends. This article examines the issues related to the conductive and radiated radio-frequency disturbances, in the range from 150 kHz to 1 GHz, of multi-MWp PV plants as designed nowadays, with high-power bifacial modules, single-axis trackers, and decentralized high-density inverters. The main features include the extensive dc and ac cabling, the capacitance toward the Earth of the PV source, the common-mode disturbance caused by inverters, the effect of safety and functional grounding, the galvanic isolation provided by step-up power transformers, and the presence of resonant circuits for common-mode leakage currents. Measurements in situ for both conducted and radiated disturbances in a 19.87 MWp plant placed in Ferrandina, South Italy, are presented and discussed. Guidelines for achieving an EMC functional safety by design are provided, raising from the analysis of the measured data.

In Part II, both skin and proximity effects in multisolid and hollow conductor arrays are accurately predicted over an ultrawide frequency range. This is accomplished through the development of recursive formulas that consider the mutual influence among all neighboring conductors, enabling accurate prediction of the current as well as field distribution within and around each conductor. The recursive formulas are developed by considering the interaction among conductors in the array using the magnetic vector potential in a recursive way. Hence, the impact of conductor size and number on the skin and proximity effects in such array is investigated appropriately. It is numerically shown that if nearby conductors have relatively large radii with small separations, an increased number of iterations is required for achieving accurate results of both current and field distributions. Further, the transfer impedances of a shielded twinax cable situated near other shields are also predicted utilizing the recursive formulas. The proposed methodology is validated by comparing with both commercial software COMSOL and HFSS, where excellent agreements are obtained.
