Abstract
A smart grid consists of a number of intelligent control systems for both power generation and system energy economy. Smart power converters are part of these systems, along with highly efficient resources and renewable energy. Although multilevel inverters are thought of as contemporary and fundamental components of high voltage power supply systems, the overall system's dependability is significantly impacted when electronic power components fail. Measurement and identification of the operating regimes and boundary conditions of the power components are key objectives in the definition and dimensioning of smart grids. The three-phase multilevel inverter, a common component of a smart grid, has a power component problem that can be detected using a novel technique presented in this research. Using this technique, single, double, and triple switch failures may be identified. The stator current analysis is the basis of the detection system, which allows for the distinction between simple and repeated switching failures. The study also examines multilevel converter models, which are methodically constructed from fundamental parts and employ modifiable subsystems to alternate between designs with various converter topologies. These models are also capable of simulating various operational situations to evaluate the control system's functionality and achieving harmonic analysis to confirm the system's accuracy.
