Study On Supply Demand Operation Of Ac / Dc Micro-Grid At Power System Failure

number of digital household electrical appliances and other devices that operate with a DC power supply is beginning to increase. Due to the increased use of technology, such as information and communication technology (ICT), the supply of electricity even in the event of a disaster has become a requirement. For this reason, two types of AC/DC microgrids are constructed and compared. One uses an uninterruptible power supply (UPS) and the other uses bidirectional inverters. In this study, the dynamic characteristics in the AC/DC microgrid in the case of power system failure are investigated. By using the UPS, it was possible to supply high-quality electric power to the load even if failure occurred. (C) 2018, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.
