A Virtual Inertia Control Strategy for DC Microgrids Analogized With Virtual Synchronous Machines [PDF]
IEEE Transactions on Industrial Electronics, 2017 In a DC microgrid (DC-MG), the dc bus voltage is vulnerable to power fluctuation derived from the intermittent distributed energy or local loads variation. In this paper, a virtual inertia control strategy for DC-MG through bidirectional grid-connected converters (BGCs) analogized with virtual synchronous machine (VSM) is proposed to enhance the ...
