Abstract

The increasing diffusion of large-scale photovoltaic (PV) systems, to be directly connected to high-voltage transmission networks, arises the need of dealing with specific technical requirements posed in grid codes by Transmission System Operator (TSO) for a feasible connection. Among them, the compliance with specific reactive power capabilities at point of common coupling (PCC), depending on active power production levels and on grid voltage values at PCC, can have significant implications in the design stage of a PV generator. In fact, the chosen size and the installation features of the DC/AC converters affect their ability of providing leading/lagging reactive power levels. Moreover, the presence of on load tap changers on the transformers could be beneficial for the PV system operation. Therefore, this paper proposes a methodology for evaluating the main factors which affect the reactive power capabilities of a PV system to be compliant with the transmission grid code requirements.
