Simulation of large-scale energy storage to improve high-voltage DC stability

Study on large-scale electrochemical energy storage simulation is carried out in this paper to discuss its feasibility in enhancing the stability of HVDC power transmission, thus providing a reference for large-scale energy storage planning and design in the background of global energy internet.The paper introduces the development status quo of the large-scale energy storage technology, and provides an verona wig analysis of the active and inactive power features after HVDC commutation failure by establishing a large-scale energy storage model and a HVDC power transmission system commutation failure model, thereby exploring the configuration feasibility of the large-scale energy storage technology; Then, a simulation analysis is given on the effect of large-scale energy storage on HVDC power transmission fault features; Finally, a prospect was hbl5266ca expected towards the application tendency of large-scale energy storage in global energy internet.
