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.
