Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity.This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind

1. Introduction With a low-carbon background, a significant increase in the proportion of renewable energy (RE) increases the uncertainty of power systems [1, 2], and the gradual retirement of thermal power units exacerbates the lack of flexible resources [3], leading to a sharp increase in the pressure on the system peak and frequency regulation
According to the current situation of wind power production and energy storage, the unit wind power production cost c 1 = 0.4 and the unit energy storage cost c 2 = 0.575. Conclusions and suggestions The research object of this paper is the wind power supply chain composed of a wind power provider and an energy storage provider.
The random and intermittent nature of wind power output has an increasingly prominent impact on grid planning and operation. For example, there is a power balance problem between wind turbines, thermal units and load, in which case there is a loss of load phenomenon, i.e. the total power generation is less than the load power, and a wind
With the acceleration of China''s energy structure transformation, energy storage, as a new form of operation, plays a key role in improving power quality, absorption, frequency modulation and power reliability of the grid [1]. However, China''s electric power market is not perfect, how to maximize the income of energy storage power station is an
Video. MITEI''s three-year Future of Energy Storage study explored the role that energy storage can play in fighting climate change and in the global adoption of clean energy grids. Replacing fossil fuel-based power generation with power generation from wind and solar resources is a key strategy for decarbonizing electricity.
2. Literature review method. The adopted procedure related to the bibliometric analysis discussed in Section 5 is similar to the one adopted in Barra et al.

Besides, energy storage (ES) is the capture of energy produced at one time for use at a later time. Essentially, ES can not only shift energy from peak-demand hours to off-peak-demand hours, but also absorb excess wind power to provide it back to the grid when desired [7]. Thus, the using of ES is helpful for improving supply reliability
