Research on Structured Electromagnetic Modeling and Model Accuracy Verification for Electrochemical Energy Storage

With the continuous emergence of various clean energy sources, the traditional “source, grid, and load” structure composed of the power generation side, grid side, and consumption side has gradually transformed into a “source, grid, load, and storage” structure. The output power of renewable energy generation has fluctuations and randomness, which can easily cause stable operation of the power grid, imbalance between source and load supply and demand, and energy quality problems. Energy storage technology can quickly respond to changes in the power system, ensuring the safe operation of the power system and effectively preventing energy waste. This article builds a fault traversal model for energy storage systems in Simulink, analyzes its control effect through simulat ion, and verifies the effectiveness of the fault control strategy.
