Magnetic coupling resonant wireless power transfer (MCR-WPT) technology enables non-contact mid-range energy transmission through resonant magnetic field coupling. In power systems, this approach overcomes the physical constraints of wired connections, enhancing both flexibility and safety in power delivery . Drawing upon advancements in misalignment-resilient wireless charging for electric vehicles, this paper systematically investigates the theoretical framework, key enabling technologies, and representative application scenarios of MCR-WPT in the context of power systems. The study focuses on critical technical aspects, including compensation network topology optimization, misalignment-tolerant coupling mechanisms, and parameter optimization algorithms. Experimental validation is conducted on a 1 kW MCR-WPT testbed. Results demonstrate that under a transmission efficiency of 86% and a horizontal misalignment tolerance of ±30 mm, the proposed system meets the requirements of diversified power applications, such as electric vehicle (EV) charging, smart grid device powering, and industrial automation. These findings establish MCR-WPT as a promising solution to facilitate the wireless transformation of future power systems.
