Abstract—Smart grid distribution and consumption communication network is one important part of smart gird communication network and the crucial technology field of smart grid. Smart grid distribution and consumption communication network due to its existing features such as large coverage, enormous number and irregular distribution of the network nodes and difficulty of network construction, has been lack of suitable communication technology and network construction mode, and become the negative factors of the development of smart gird communication network and the constraints of the application and development of smart grid distribution and consumption business. This paper makes great efforts on the research about lots of power communication technologies and the existing scheme of power communication network construction, considers the characteristics of business needs, technical prospects and economic cost, and then proposes a widely applicable smart gird distribution and consumption communication network architecture, including smart grid distribution and consumption communication network model, layered network structure, and a series of applicable networking programs.
