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] …

This thesis considers the problem of determining impedance parameters of a solar cell in operation. Typically, solar cell devices are characterized by the manufacturer using empirical data prior to placing the solar cell in use. There are a number of solar cell degeneration mechanisms that are of interest to measure or detect. Therefore, active measurement of solar cell impedance parameters periodically over time is advantageous. We propose a methodology developed from a Thévenin equivalent model of a typical solar cell. This method allows periodic updating of the solar cell’s parameters which can be used to update the cells characterization and/or …

Microgrid monitoring focusing on power data, such as voltage and current, has become more significant in the development of decentralized power supply system. The power data transmission delay between distributed generator is vital for evaluating the stability and financial outcome of overall grid performance. In this thesis, both hardware and simulation has been discussed for optimizing the data packets transmission delay, energy consumption, and collision rate. To minimize the transmission delay and collision rate, state-action-reward-state-action (SARSA) and Q-learning method based on Markov decision process (MDP) model is used to search the most efficient data transmission scheme for each agent device. …
