How a Small Wind Electric System Works. Wind is created by the unequal heating of Earth''s surface by the sun. Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine''s blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator.

1. Introduction. Energy storage systems (ESS) are continuously expanding in recent years with the increase of renewable energy penetration, as energy storage is an ideal technology for helping power systems to counterbalance the fluctuating solar and wind generation [1], [2], [3].The generation fluctuations are attributed to the
Energy storage is a crucial technology for facilitating the integration of renewable energy sources (RES), such as wind and solar energy, into the electrical grid.
