The advent of quantum computing has heralded unprecedented possibilities in diverse scientific domains, including electrical engineering. This research paper delves into the innovative integration of quantum computing methodologies for the time-domain simulation of electromagnetic transients in interconnected power systems. Electromagnetic transients are pivotal phenomena that influence the stability, reliability, and efficiency of power systems, necessitating accurate and rapid simulation techniques. Classical computational paradigms, albeit powerful, encounter substantial limitations in terms of computational speed and capacity when dealing with large-scale, complex interconnected power networks. To address these challenges, this paper introduces quantum algorithms that leverage the principles of superposition and entanglement, ensuring a quantum leap in simulation capabilities. A comprehensive comparison with conventional simulation methodologies is presented, highlighting the quantum algorithms' superior efficiency and precision. The quantum circuit models for various power system components are meticulously constructed and optimized for quantum resource utilization. Furthermore, the paper explores error mitigation strategies and quantum error correction codes tailored for power system applications, ensuring robustness in the presence of quantum noise and decoherence. The empirical results, obtained from simulations on quantum processors and simulators, underscore the substantial advantages and potential of quantum computing in revolutionizing electromagnetic transient analysis. This research not only paves the way for accelerated and accurate simulations but also contributes to the enhanced stability and reliability of modern interconnected power systems.
