The generation side of a power grid mainly operates with high-voltage electricity across a long distance. Generally, the RE systems are utilized as a distributed energy resource (DER) system at the distribution side, whereas the usage of RE systems at the generation side is rarely found with ESS-integrated power grids.
In this case, the energy storage side connects the source and load ends, which needs to fully meet the demand for output storage on the power side and provide enough electricity to the load side, so a large enough energy storage capacity configuration is a must.
However, due to the intermittent and unstable characteristics of renewable energy, it is difficult to meet the demands of the power load side in practical applications.

Few current and past commercial projects of ESS around the globe, and potential directions to promote ESS are discussed.
