摘要：
The paper presents modeling, control and stability analysis for a DC nanogrid working in remote areas or islands. The small-signal transfer function of a DC nanogrid is derived from the small-signal transfer functions of every single converters of the system. From this transfer function, the system stability is analyzed and the secondary controller is designed. Simulation and experimental results are used to verify a stable operation of the DC nanogrid system during load changes. The control algorithm also allows a DC nanogrid to be connected with others to exchange power. More importantly, the interconnection of multiple DC nanogrids has no effect on the stability of each individual nanogrid.
