Fault characteristics analysis of distributed energy storage distribution network considering low voltage ride through

This paper demonstrates that energy storage plays an important role in the security and stability of the distribution network, provides an inner and outer loop control strategy for energy storage converters, and lists the reference value formulas for active and reactive currents when the energy storage system carries out low-voltage ride-through. Finally, the distribution network model is established using Simulink in Matlab, and the storage model containing the control strategy of this paper is inserted into the constructed distribution network model, with a single ground fault set up, comparing the voltage at the insertion point with and without storage, to analyze the role of energy storage in the distribution network.
