摘　　要：随着我国“双碳”目标的推进,新型电力系统加速发展。变流器作为核心设备,其建设模式的选择至关重要。笔者深入探讨变流器的类型及应用场景,重点分析跟网型、构网型及混合型建设模式的优缺点,并结合用户资源与电网特性,提出合理的建设模式选择策略。研究表明:在新能源低比例阶段,用户以跟网型建设模式为主;而在新能源高比例阶段,构网型及混合型建设模式更有利于电网的稳定运行。建设模式的选择应综合考虑用户资源、电网特性及新能源比例,以实现新能源电力系统的高效稳定运行。With the advancement of China's“dual carbon”goals,the development of new power systems has accelerated.As a core component,the selection of converter construction modes is critical.This study conducts an in-depth investigation into converter types and application scenarios,focusing on analyzing the advantages and disadvantages of grid-following,grid-forming,and hybrid construction modes.By integrating user resources and grid characteristics,a rational selection strategy for construction modes is proposed.The research demonstrates that during low renewable energy penetration stages,grid-following modes dominate for user-side applications,while grid-forming and hybrid modes prove more effective in ensuring grid stability under high renewable energy penetration conditions.The selection of construction modes should holistically consider user resources,grid characteristics,and renewable energy penetration levels to achieve efficient and stable operation of renewable-integrated power systems.
