Introduction. Electrical Energy Storage (EES) refers to a process of converting electrical energy from a power network into a form that can be stored for converting back to electrical energy when needed [1], [2], [3]. Such a process enables electricity to be produced at times of either low demand, low generation cost or from

Electrical energy storage systems. An electrical energy storage system is a system in which electrical energy is converted into a type of energy (chemical, thermal, electromagnetic energy, etc.) that is capable of storing energy and, if needed, is converted back into electrical energy.
This generates an electric field within the cell, which forces electrons to flow in a certain direction, producing electricity. The more intense the sunlight striking a PV panel, the more electricity it can generate. PV systems work very efficiently even on cloudy days and are highly reliable with a long lifespan.
