摘要
为了减少化石燃料的使用,越来越多的可再生分布式电源被应用到电网中。微电网是分布式电源的有效利用方式,但是在微电网的并网运行中,分布式电源的频率和电压波动会对主电网产生很大的影响,而直流微电网可以抑制这些波动的干扰。同时,用户终端的直流负荷日益增长,直流电网将是未来电网的发展趋势。基于此,构建了一个使用直流电的局域网络,并利用电能信息进行直流电能的分配和路由。在直流局域网中,首先将直流电源进行数字化分组,然后通过电能路由器传输分组电能及其信息,实现分布式电源和负载之间的电能供需平衡。最后给出了基于连续最短路径的电能路由算法,并对算法进行了仿真和分析。
To reduce the use of fossil fuels,more and more renewable distributed power is applied in power grid. M icroGrid 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.
