Development Status and Engineering Application of Grid-forming Converter Technology
摘要
Abstract
With the ongoing advancement of new power system construction in China,the green and low-carbon transformation of energy is accelerating and upgrading.The proportion of renewable energy installed capacity has significantly increased,and a large number of power electronic devices have been integrated into the power grid.Great changes,including reduced moment of inertia and weakened reactive power support capabilities,have taken place on the source,load,and grid sides of the power system.In this context,the power system requires equipment to possess new characteristics,namely corresponding features of synchronous machines and the ability to actively support the power grid.This paper elaborates on the main characteristics of the new power system from three aspects:demands of the new power system,grid-forming converter technology,and typical equipment and engineering applications.In addition,the working principle and various topologies of grid-forming converters are analyzed.Subsequently,based on the existing research and practical projects,the engineering application cases of four typical grid-forming converters,namely grid-forming flexible DC,grid-forming static compensator,grid-forming static var generator,and grid-forming energy storage,are described.Finally,development suggestions and prospects are proposed based on the current research status of grid-forming technology,providing references for further engineering applications.关键词
