Smart grid technology can be best utilized by having proper grid supporting equipment. This paper demonstrates the use of a three-phase, 9-level, hybridised cascaded multi-level inverter topology in a smart grid. A pulse width modulation scheme with phase disposition is employed in this inverter to control the firing signals to operate this circuit. These firing signals can be monitored and controlled for optimal usage in smart grid operation. Operational principles with switching equations are described in detail. Crucial voltage identification has been performed by analyzing the THD in output during source shortages by performing Fast Fourier transform analysis. Least THD of 15.82% is attained in the output voltage waveform of the proposed three phase inverter topology.

Smart grid technology is a radical approach for improvisation in existing power grid. Some of the significant features of smart grid technology are bidirectional communication, AMI, SCADA, renewable integration, active consumer participation, distribution automation, and complete management of entire grid through wireless communication standards and technologies. Management of complex, hierarchical, and heterogeneous smart grid infrastructure requires data collection, storage, processing, analysis, retrieval, and communication for self-healing and complete automation. Data mining techniques can be an effective solution for smart grid operation and management. Data mining is a computational process for data analysis. Data scrutiny is unavoidable for unambiguous knowledge discovery as well as decision making practices. Data mining is inevitable for analysis of various statistics associated with power generation, distribution automation, data communications, billing, consumer participation, and fault diagnosis in smart power grid.
