Development of a Methodology for Data Flow over TCP/IP for a Protection Scheme in Smart Grids

The real-time data flow over TCP/IP (Transmission Control Protocol/Internet Protocol) between running simulation models allows evaluating the designed models and its communication capabilities. This paper presents a proposed methodology for the data flow in real time between modeled components of a protection scheme with local control, for a distribution system in Smart Grids. The proposed methodology specifies the characteristics of the modeled components, as Intelligent Electronic Devices (IEDs) and a Local Control Center (LCC). In addition, the communication network architecture based on TCP/IP protocol to allow the data flow is selected. In order to evaluate the methodology, a case study is implemented in MATLAB/Simulink. In the case study test, the LCC response time is measured. The obtained results in the LCC response time measurements were lower than 110 ms.
