在新型电力系统建设背景下,构网型技术已成为解决微电网惯量缺失、频率波动和电压失稳等核心问题的关键技术。系统梳理了构网型控制策略的技术原理与发展路径,并基于典型工程案例分析了构网型装备从示范验证到智能化发展的3个阶段;聚焦微电网孤岛运行、并网切换及多微网协同3大典型场景,深入探讨了构网型技术在提升系统稳定性方面的功能优势与实现机制;针对控制实时性、设备可靠性和经济性等现存挑战,提出了智能算法优化、新型拓扑开发和多能域协同等未来发展方向,为构网型技术在微电网中的规模化应用提供理论支撑。
Against the backdrop of the construction of a new-type power system,grid-forming technology has emerged as a crucial solution to the core challenges in microgrids,including inertia deficiency,frequency fluctuations,and voltage instability.The technical principles and development trajectories of grid-forming control strategies are systematically reviewed.Based on typical engineering cases,the three-stage evolution of grid-forming equipment from demonstration verification to intelligent development is analyzed.Focusing on three representative scenarios in microgrids,namely islanded operation,grid-connected switching,and multi-microgrid coordination,the functional advantages and implementation mechanisms of grid-forming technology in enhancing system stability are thoroughly investigated.To address existing challenges such as control real-time performance,equipment reliability,and economic efficiency,future development directions including intelligent algorithm optimization,novel topology development,and multi-energy domain coordination are proposed,which provide theoretical support for the large-scale application of grid-forming technology in microgrids.
