Architecture of IEEE standard Low Voltage Direct Current (LVDC) Distribution System

The necessity for adequate and reliable electrical distribution systems that can maintain essential power supplies during disasters has been underscored by an increasing rate of natural catastrophic events and extreme weather situations. A Low Voltage Direct Current (LVDC) distribution system connected with Distributed Energy Resources (DERs) for disaster-resilient power delivery is modelled and analysed in this research. Compared with traditional LVAC distribution systems, the LVDC system is intended to increase power reliability, reduce conversion losses, improve operational efficiency, and enable the smooth integration of renewable energy sources. To evaluate system performance under various generation and load conditions, a comprehensive simulation model of an IEEE Standard prototype LVDC distribution system architecture is developed in MATLAB/Simulink.
The recommended LVDC system successfully preserves voltage stability, enhances power quality, and guarantees dependable operation of critical loads during disaster-induced disruptions, according to simulation results. For emergency power distribution in disaster-prone areas, hospitals, shelters, and important infrastructure applications, the proposed model offers an efficient and resilient solution.
