  Direct current (DC) grids have been developed to facilitate the ongoing transition to future power systems by replacing conventional AC networks. High-voltage DC (HVDC) systems transferring large amounts of power from remote areas have been studied for several decades. With the proliferation of DC sources and loads, such as photovoltaic (PV), LED lighting systems, electric vehicles, and data centers, medium-voltage (MV) or low voltage (LV) DC networks have been investigated to improve energy efficiency and maximize power transfer capability. Recently in South Korea, a government-funded project aimed at developing MVDC components, operational methods, and constructing a pilot plant is underway. In this seminar, an overview of DC distribution networks and research on its operational methodologies will be introduced from the perspective of power system operators.
