SEP 2.0 Based User-side Communication Technology For Smart Grid

Smart grid demand-side communication technology play a significant role in ensuring the bidirectional communication between the user side and the utility.Due to the variety of user equipment and Io T technology,it is very important to provide a common set of data transmission and application interfaces for smart grid to improve the inter-operability of various Io T.Therefore,this paper studies the smart grid demandside communication technology based on SEP 2.0,and proposes the research and development scheme of the upper-middleware of SEP 2.0 to expand the application scope of SEP 2.0 in the smart grid user side.First of all,this section reviews the architecture of the SEP 2.0 standard and that of the Simple Link Wi-Fi solution provided by TI,respectively,providing a necessary theoretical support for the upper-middleware of SEP 2.0.Secondly,this paper puts forward the research and development scheme of SEP 2.0 upper-middleware based on simplelink Wi Fi solution,and builds the development framework of SEP 2.0.In terms of hardware,Simple Link Wi-Fi CC3220 SF Launch Pad is used.In the aspect of software,through the processing of URI query string and XML file,the data interaction between power grid and user side is realized.Through the setting of security items,the data can be transmitted safely.Through the setting of m DNS,service name and TXT record format,the server device containing the function set to be accessed can be located.Finally,based on SEP 2.0 upper middleware,the application case of smart meter is developed,which mainly analyzes and develops the communication process from the three functions of metering,pricing and billing to verify the effectiveness of the developed SEP 2.0 upper middleware.
