基础资料，我觉得对于初学者相当有用的。它是基于matlab环境开发的，可以在其中找到你具体想要处理的方面！(This is the fundamental material for the initial people who study the image processing. it is baed on Matlab code. People can find the specific knowledge which you want!)

潮流计算程序，通过IEEE30节点验证，程序可以正确运行。(Distribution power flow calculation. IEEE30 node validation)
