Abstract	The characteristic parameters of micro-grid determine its transient response and stability. Due to uncertain load changes as well as large-scale intermittent energy accesses, the micro-grid systems are always subjected to large number of random disturbances which results in micro-grid structure parameters change. To solve this problem, this paper presents a novel model for characteristic parameters calculation of DC micro-grid. The derived model is based on real-time measurement of the transient current which quickly and accurately calculates the characteristic parameters change. A controller is designed using the derived model and simulation is carried out to verify the derived model.
