The AC distribution system is adopted because of simple and easy protection scheme. In contrast, the protection of DC grid is difficult because of no current zero crossing. The main advantage of DC microgrid is reduced losses so higher efficiency than AC. Conventional protection techniques in DC microgrid completely de-energies the DC link. A new protection scheme for DC micro-grid against line to line fault is presented in this paper. The scheme isolates only faulty section from the DC grid… Expand
