electrical equipment energy storage delay setting

How does time delay affect the performance of a power system?

The time delay is able to worsen the performance of the power system, and even bring about instability. Based on the Artstein transform theorem, the model of the power system with communication delay is transformed into a model without delay. Meanwhile, the output of the external energy storage should be limited in practical power systems.

Do energy storage technologies improve voltage and power stability?
