Technical FAQs 4

What is a microgrid based energy storage system?

Microgrid comprises renewable power generators with the battery storage system as power backup. In case of grid-connected microgrid, energy storage medium has considerable impact on the performance of the microgrid. Lithium-ion (LI) and lead-acid (LA) batteries have shown useful applications for energy storage system in a microgrid.

Are lithium ion and lead-acid batteries useful for energy storage system?

Lithium-ion (LI) and lead-acid (LA) batteries have shown useful applications for energy storage system in a microgrid. The specific energy density (energy per unit mass) is more for LI battery whereas it is lower in case of LA battery.

How battery energy is stored in a microgrid system?

Batteries in the applied microgrid system are utilized as storage devices. The battery system buffers the excessive energy through low power demand and releases its stored energy through peak demand or while inadequate electricity is generated from the PV system. The battery energy that can be stored is calculated as seen below:

Why is a battery required in a microgrid system?

The battery is required to improve the performance of the microgrid. This device responds to short-time disturbances and variations in solar irradiation. The number and capacity of batteries per string are adjusted to the PV generation’s capacity and output voltage. Batteries in the applied microgrid system are utilized as storage devices.
