Multi-port isolated H-bridge converter has the features of high voltage conversion ratio, bidirectional power flow and high-power capacity, which is suitable to be integrated into DC microgrids. This paper uses three-port isolated H-bridge converters as the interfacing converters in power generation units which comprise distributed generation (DG) and energy storage (ES) in DC microgrid. The topology...
Microgrid, as a new effective way for large scale new energy and renewable energy power generation systems connected to the grid, injects new vigor into the power system. Focusing on the characteristics of P-f (active power versus frequency) droop and Q-V (reactive power versus voltage) droop, on the basis of analyzing the variable slope coefficient of droop characteristic, a droop control method...
Distributed generation (DG) injects new vigor into the power system, but it sometimes brings unfavorable factors influencing the power quality of distribution network. In this paper, the Dynamic Voltage Restorer (DVR) is introduced to the distribution network to improve the power quality. In view of that the detection of voltage compensation is the key factor that influences the effect of voltage...
