Abstract
As an indispensable part of the modern power system, the definition of the power electronics technology covers the technology of using the semiconductor switching devices to transform and control the electric energy. Its core components include semiconductor devices, power converters, controllers, and drive circuits, which work together to achieve the efficient conversion and precise control of electrical energy. Power electronics technology can be classified according to its different application fields, such as DC transformation, AC transformation, rectification, etc., and is widely used in energy, transportation, industry and other fields. Power electronics technology plays a crucial role in the smart grid. In the process of power generation, the power electronics technology has realized the efficient utilization of energy and the optimal operation of the power system through the grid connection and power control of renewable energy, and the upgrading and transformation of traditional power plants. In the transmission link, the flexible AC transmission system and HVDC transmission and HVDC transmission technology improve the flexibility and efficiency of transmission. In the distribution process of power distribution, the power electronic technology and power quality and governance technology of the intelligent distribution network have improved the intelligent level and power supply quality of the power grid. On the user side, power electronics technology realizes the accurate matching between power supply and user demand through smart meters and user-side energy storage and demand response technology. The application of power electronics technology is faced with challenges such as technology compatibility, high cost input, fierce market competition and network security threat. To meet these challenges, it is necessary to increase technological innovation, reduce production costs, implement differentiated competitive strategies, and strengthen network security protection. Through these countermeasures, power electronics technology will play a more important role in the smart grid and promote the sustainable development and progress of the power industry.
