With the phase-out of conventional energy sources, the inertia of the power system is decreasing. This inertia, which is contained in the rotating parts of traditional power plants, ensures the stability of the system in the event of disturbances. The connection of electric vehicles and other large loads increases the burden on the power system, and in the event of a production outage, the stability of the grid may be reduced. Stability can be improved through the proper regulation of battery energy storage systems.
This thesis presents the advantages of energy storage systems, their impact on the grid, and the challenges in regulation, particularly concerning three-phase short-circuit currents. The main focus is on short-circuit current regulation and methods to enhance system stability. The aim of the thesis was to study voltage and current regulation methods and their impact on grid quality.
In Simulink, we designed a simple network with a battery and a grid-connected converter and analyzed Simulink’s capabilities for modeling appropriate converter regulation.
