Abstract
The load of the rural grid is changeable and irregular, it is easily affected by the large power grid. This paper proposed the concept of “rural nano grid”, which can combines the power generation system, energy storage system and control system into unified whole. The rural nano grid can work in the grid-connected mode and off-grid mode when there are some faults in large power grid, so that power supply in rural areas can be sustainable. Then this paper proposed a new kind of LLC resonant DC-DC converter, which can ensure the power generation system of the rural nano grid supply power for the load and energy storage system under wide load range with high efficiency that can be appropriate for characteristics of the rural nano grid. At last a prototype with a power rating of 5kW is designed and built up to verity validity and correctness of the converter proposed in this paper.
