As DC power sources and DC loads are connected to the power system on a large scale, the conventional AC distribution systems are reaching their limitations. In response, medium-voltage DC (MVDC) distribution systems are emerging as an alternative for the next-generation distribution system. In the Republic of Korea, the goal is to operate a hybrid AC/DC distribution system by 2030, and partially replacing existing AC distribution systems with DC distribution systems is being considered. This article investigates the issue of nearby transformer saturation that may occur when an MVDC distribution system replaces an existing AC distribution system and introduces countermeasures to prevent transformer saturation.
