构网型储能变流器及控制策略研究
摘要：具有高比例新能源和高比例电力电子设备的新型电力系统是实现“双碳”目标的重要手段，但新型电力系统也会带来一系列不稳定的问题。在新型电力系统中，构网型控制技术(grid-forming control technology，GFM)具有电压支撑和主动惯量特性，以此替代同步机实现电网支撑，并维持电力系统稳定性，因此GFM具有广阔的发展和应用前景。基于此，首先，对储能变流器的拓扑进行简要介绍，并针对GFM技术的控制特点为其选型；其次，对于现有的构网型控制策略进行总结分析；最后，提出当前研究难点以及发展过程中所面临的问题和挑战，为构网型控制技术今后的发展建设提供思路。
Abstract:The new power system with high proportion of new energy and power electronic equipment is an important means to achieve the goal of “double carbon”, but the new power system will also bring a series of unstable problems. In the new power system, grid-forming control technology (GFM) has the characteristics of voltage support and active inertia, which can replace synchronous machine to realize grid support and maintain power system stability. Therefore, GFM has a broad development and application prospect. Based on this, this paper first briefly introduced the topology of energy storage converter, and selected its type according to the control characteristics of GFM technology. After that, a reasonable summary and analysis of the existing control strategies of GFM was made, the current research difficulties, problems and challenges in the development process and the research prospects were put forward, and the ideas for the construction of grid-forming construction were provided.
