Energy storage, such as batteries, can also be distributed, helping to ensure power when solar or other DER don''t generate power. Electric cars can even store excess energy in the batteries of idle cars.

Overview of energy storage systems in distribution networks:

An electricity grid can use numerous energy storage technologies as shown in Fig. 2, which are generally categorised in six groups: electrical, mechanical, electrochemical, thermochemical, chemical, and thermal. Depending on the energy storage and delivery characteristics, an ESS can serve many roles in an electricity market [65].
