Abstract
Under the background of the current energy structure transformation and smart grid construction, the control strategy optimization of doubly-fed extraction and storage unit, as an efficient and flexible energy storage mode, is particularly important. The purpose of this study is to improve the stability and regulation ability of doubly-fed storage units by introducing virtual synchro technology, so as to meet the new requirements of modern power grid for energy storage systems. By simulating the operation characteristics of the synchronous generator, the douply-fed generator can better simulate the behavior of the traditional synchronous generator, so as to improve the stability and regulation performance of the power grid. This strategy also effectively reduces the impact of the unit in the process of grid connection and improves the overall stability of the power grid. In this study, virtual synchro technology is introduced to optimize the control strategy of doubly-fed extraction and storage unit, which significantly improves the operation performance of the unit and the stability of the power grid. This innovative control strategy is expected to provide strong support for the construction and development of smart grid, and also lay a solid foundation for the further promotion and application of doubly-fed extraction and storage technology.
