6 FAQs about Grid-side peak load storage

What is the current application of energy storage in the power grid?

As can be seen in Table 3, for the power type and application time scale of energy storage, the current application of energy storage in the power grid mainly focuses on power frequency active regulation, especially in rapid frequency regulation, peak shaving and valley filling, and new energy grid-connected operation.

What is the difference between grid side and load side?

The grid side includes the entire power system and pumped storage. The load side includes conventional loads and loads with energy storage char-acteristics, such as electric vehicles, which are mobilised as the backup capacity of the system participates in power grid dis-patching and alleviates the contradiction between supply and demand.

How to reduce peak load in energy storage systems?

By operating these storage systems using the coordinated control strategy, the maximum peak load can be reduced by 44.9%. The rise in peak load reduction increases linearly with small storage capacities, whereas saturation behavior can be observed above 800 kWh.
