One of the most important and complex tasks in power engineering is the analysis of power systems under fault conditions. The detection and analysis of these faults are important to guarantee that the dependability and stability of the power system does not decline as a result of a critical event such as a fault. This thesis will conduct research on how a power system under fault conditions behaves and will examine the various scenarios of faults such as three-phase, single line-to-ground, line-to-line, and double line-to-ground faults. A simplified method based on symmetrical components is used to construct the mathematical models …

With the increasing requirements on environment-friendly and sustainable clean energy [1], people have paid more attention to renewable energy around the world in the past few decades. As a result, power systems have undergone a paradigm shift from centralized generation to distributed generation. Smart grids, which are a combination of power systems and communication networks, were proposed to allow power systems to meet future challenges. In smart grids, especially in AC microgrids, converters play an important role in many areas including microgrid integration, uninterrupted power supply, and flexible alternating current transmission systems. The inverter is a power conversion device [2] …
