Liu et al. proposed a wind-heat energy storage system that may effectively increase the utilization rate of all wind energy and include the power generation cycle and molten salt storage [7].Wind
The stored energy is later released to generate additional power for the customer. Energy balance of a whole cycle is observed by controlling the state of the air storage tank. The wind generation power rating will be adjusted, and the energy storage/release profiles will be re-designed if the supply fails to meet the demand.
Examples include tank thermal energy storage, using water as a storage medium; solid-state thermal storage, such as with ceramic bricks, rocks, concrete, and packed beds; liquid (or molten) salts
As wind power installations grow in size and capacity, flow batteries can adapt to meet the increasing storage demands. The external tanks that hold the electrolyte solutions can be modified or added to, making it a flexible option for scaling energy storage infrastructure. Challenges in wind energy storage, such as intermittency, energy
Wind power storage development is essential for renewable energy technologies to become economically feasible. There are many different ways in which one can store electrical energy, the following outlines the various media used to store grid-ready energy produced by wind turbines. For more on applications of these wind storage

In this sense, many operating strategies for wind-ESS are considered.
The development of the wind energy industry is seriously restricted by grid connection issues and wind energy generation rejections introduced by the intermittent nature of wind energy sources. As a solution of these
What is thermal energy storage? Thermal energy storage means heating or cooling a medium to use the energy when needed later. In its simplest form, this could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less plentiful.
As a solution of these problems, a wind power system integrating with a thermal energy. storage (TES) system for district heating (DH) is designed to make best use of the wind power in the
