Application and Analysis of Smart Meter Data along with RTL SDR and GNU Radio

Introduction of smart meter offered fine grained information about the energy consumption of customers. To categorize the appliances consuming the energy, the Electromagnetic Interferences emitted by them are measured using Realtek Software Defined Radio. To avoid the frequency range mismatch of the interferences and the input frequency range of Realtek Software Defined Radio, an up converter is used. The interferences can be processed by using a GNU radio. The time stamped signals are stored as DAT file format. Disaggregation of appliances consuming the power is attained by comparing the results with that of smart meter results. To achieve this task smart meters are employed to calculate the total energy consumption. Smart meter data will also be time stamped. The data collected by the smart meter is processed by Raspberry Pi and is stored in memory. Both the GNU radio data and smart meter data are compared to conclude final results. This algorithm is superior to the existing one as it helps to disintegrate the multiple appliances consuming power at the same time.
