Adaptive control strategy for energy storage and grid frequency adjustment combined with quadratic function

An equivalent regional power grid model containing energy storage batteries was constructed. By studying the participation of batteries in regional power grid frequency adjustment, it has been verified that the participation of energy storage batteries in power grid frequency adjustment has a significant improvement effect on power grid frequency stability; Based on the fixed power operation of energy storage batteries, considering the state of charge (SOC) of the battery as an important factor, the SOC was improved as a feedback signal. In addition, research has shown that the SOC feedback mechanism not only improves the accuracy of grid frequency adjustment, but also helps optimize the battery's charging and discharging strategies, thereby avoiding the risk of over discharging or overcharging and further extending the battery's lifespan. This improvement plan provides more reliable technical support for the application of energy storage systems in future power grids.
