On the contrary, electrical energy can be purchased from the main grid at off-peak times when the per-unit electricity cost is comparatively low and can store the energy using ESS. Generally, the cost of electricity is very high during peak hours. The stored energy can be used to deal with excessive demand or can be sold to the main grid.
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.
