Against the backdrop of global climate change and the increasing depletion of fossil fuels, the development and utilization of renewable energy are receiving
increasing attention from the international community,Vigorously developing renewable energy has become a consensus among countries around the world.
As an important component of renewable energy, wind power generation has the advantages of short construction period, flexible installation mode,high reliability,
simple operation and maintenance, and small footprint.
In recent years,China has continuously introduced a series of encouragement and preferential policies,vigorously supporting the construction of wind power projects,
and the wind power market has developed rapidly,And gradually shift from coal-fired power generation to environmentally friendly wind power generation.
Although wind power generation has many advantages,it also has problems such as intermittency and volatility.
In order to solve these problems and improve the reliability and stability of wind power generation systems, energy storage technology has emerged.
Energy storage technology can store the excess electricity generated by wind power during restricted periods and output it during non restricted periods,
thereby reducing wind power curtailment and increasing electricity revenue.
At the same time,energy storage devices can also bring benefits to wind power projects by reducing grid assessment costs
and participating in electricity market transactions.
In terms of national policies, both central and local governments have introduced policies to support or even require wind farms to support energy storage.
These policies can be divided into four categories: general encouragement,subsidies,priority construction,and mandatory allocation.
Although most policies currently remain at the stage of general encouragement and priority construction,and there are few policies that provide
substantial subsidies for wind farm energy storage,the industry generally believes that with technological progress and cost reduction,energy storage
will become an indispensable part of wind power development.
Wind energy storage is a technology that utilizes wind energy for energy storage,Its working principle mainly includes four links:
wind energy collection, energy storage device,energy storage control system,and electric energy utilization:
1. Wind energy harvesting:
Converting wind energy into electrical energy through wind turbines.
Wind turbines are typically composed of rotating wind turbines and generators,
When the wind drives the wind turbine to rotate, the generator will convert mechanical energy into electrical energy.
2. Energy storage device:
Transport the electrical energy generated by wind turbines to the energy storage device for storage.
Energy storage devices typically use batteries,supercapacitors,or devices used to generate compressed air.
These energy storage devices can effectively store electrical energy for release and utilization when needed.
3. Energy storage control system:
Controls and manages the inflow and outflow of electrical energy,as well as the charging
and discharging process of energy storage devices.
The charging and discharging of energy storage devices can be regulated to achieve the most efficient energy utilization and storage.
4. Electricity utilization:
When needed,convert the electricity stored in the energy storage device into electricity and supply it to the power system
Or use other electrical equipment.
This can greatly improve the reliability and sustainability of wind power generation,enable wind energy to be converted into electrical energy supply at any time,
regardless of whether wind energy exists or not.
2、 Core value of wind energy storage
The core value of wind energy storage technology is mainly reflected in the following aspects:
1. Improve wind energy utilization:

2. Enhance the stability of the power system:
Wind power generation has intermittency and volatility,which can have an impact on the stability of the power system.
Through energy storage technology, the output power of wind power generation can be smoothed, enhancing the stability of the power system.
3. Promoting the development of clean energy:
Wind energy storage technology can help promote the development of clean energy and reduce dependence on fossil fuels,Reduce greenhouse gas emissions
and achieve sustainable development.
4. Creating economic benefits:
Energy storage devices can contribute to wind power projects by reducing grid assessment costs,participating in electricity market transactions,
and other means Bring profits. Meanwhile, with the continuous advancement of energy storage technology and the decrease in costs,the economic benefits of
wind energy storage projects will also continue to improve.
