Grid Integration of DC Buildings: Standards, Requirements and Power Converter Topologies

Abstract: Residential dc microgrids and nanogrids are the emerging technology that is aimed to promote the transition to energy-efficient buildings and provide simple, highly flexible integration of renewables, storages, and loads. At the same time, the mass acceptance of dc buildings is slowed down by the relative immaturity of the dc technology, lack of standardization and general awareness about its potential. Additional efforts from multiple directions are necessary to promote this technology and increase its market… Show more

“…Residential droop-controlled dc microgrids with a nominal voltage of 350 V and droop control range of ±30 V are being standardized in the EU [26]. This study analyzes stepup/down PPC technology to provide optimized solutions for integrating PV strings in 350 V residential droop-controlled dc microgrids.…”

“…energy distributed systems and, at the same time, they are considered the key enabling technology for the urgent green energy transition [1]. A residential nanogrid (nG) (for example, a prosumer-based residential building) is one of the high-interesting scenarios where we can find such kind of distributed system [2], [3], [4]. Few years ago, those power electronic-based energy distributed systems were typically operated in grid-following (GFL) mode, acting as current sources exchanging active and reactive power [5], [6].…”

“…Regarding the advantages of using DC microgrids, i.e., high reliability and higher efficiency, DC microgrids in the distribution network are attracting more attention [7][8][9][10]. Although some DC nano/microgrids are designed for off-grid operation, in most cases, these microgrids must be connected to the AC grid [11]. Connecting to the main AC grid not only increases the reliability of the electricity supply, but it also can transfer the excess produced power into the grid and bring economic benefits.…”
