Abstract

Abstract:

To reduce the use of fossil fuels, more and more renewable distributed power is applied in power grid. Micro-Grid is an effective utilization mode for distributed generation；however, during the grid-connected operation of micro-grid, the frequency and voltage fluctuation of distributed generation will have great influence on main power grid. DC micro-grid can suppress the interference of these fluctuations. At the same time, the DC load of user terminal is increasing, and the DC grid will be the development trend of the future grid. Therefore, we construct a local network with using DC, and use the information of power for dispatching and routing DC power. The digital packet should be carried out for DC power in the DC local network. Then, the power supply and demand balance between distributed generation and load can be realized by transferring the power and its information through power routers. Finally, we present the power routing algorithm based on continuous shortest path, and carry out the simulation and analysis of this algorithm.
