Theoretical Study of Inertia Support Technology for Power Grids Based on Vacuum Shaftless Maglev Flywheel Energy Storage
摘要
Abstract
With the grid-connection rate of renewable generation continuously increasing,synchronous power grids are experiencing gradually reduced inertia.This paper proposes an inertia support technique based on vacuum shaftless magnetic-levitation(maglev)flywheel energy storage to bolster inertia in grids with high shares of renewable energy.It begins with a review of domestic and foreign methods for addressing inertia deficiency in synchronous grids,along with their respective pros and cons.The fundamental principle of inertial response is then analyzed at two levels:the single synchronous generator level and the regional grid level.Next,the mechanism of vacuum shaftless maglev flywheel energy storage and the two distinct rotor structures are introduced,and two inertia support techniques are presented:virtual inertia support based on vacuum shaftless maglev flywheel energy storage and physical inertia support based on vacuum shaftless maglev flywheel synchronous machines.Key parameter configurations for the two techniques are discussed,including capacity,flywheel size,and mass,for scenarios with varying renewable energy penetration.Finally,the characteristics of the two techniques are compared and conclusions are drawn.This study demonstrates that inertia support based on vacuum shaftless maglev flywheel energy storage can effectively enhance inertia in grids with high renewable energy penetration,offering a novel approach to ensuring grid stability.关键词
