Abstract
Energy storage technologies are becoming ever more important in power systems because of the increasing implementation of renewable energy sources and because of its technical, economic and environmental benefits. It is important to understand how these technologies operates, their effect on the traditional grid system and how they can be effectively utilized for industrial, domestic and commercial customers. This thesis provides an overview of the existing energy storage technologies. It highlights their importance in power systems and explains how they are being employed in power systems. This thesis also highlights the operation of the Superconducting Magnetic Energy Storage system
AI Summary
This thesis evaluates the feasibility of customer-sited energy storage by reviewing existing technologies, their operating characteristics, applications, costs, and technical readiness for grid-connected and off-grid users. It develops a comparative framework for selecting storage technologies and proposes a Pseudo-Adiabatic Compressed Air Energy Storage concept as a potential large-scale alternative with lower geographic constraints than pumped hydro. The work also develops and simulates a voltage-source-converter-based Superconducting Magnetic Energy Storage system in MATLAB/Simulink/Simscape to examine its charging, discharging, and power-conditioning behavior. The simulation produced a low total harmonic distortion and supported the suitability of SMES for fast-response power-quality applications. The thesis concludes by identifying opportunities to improve the SMES model and further evaluate advanced storage technologies for power-system applications.
