But since most of the large solar PV plants are built in areas far from the load, the world is moving today to transfer power directly from solar panels to high voltage HVDC grid, due to the advantages that HVDC provides such as lower transmission loss, low cost and higher efficiency compared to HVAC. In this paper, we present an overview of recent studies dealing with Photovoltaic Power Plant Connections to HVDC Grid and the comparison between these systems.enArticle
