Problems in the development of wind power Wind power is a very important area in the field of new energy. With its environmental protection and green features, it has become a key choice for developing new energy in China and many countries with abundant wind resources.

At present, China's wind power industry still lacks a complete road map. Although there are medium and long-term plans, the overall speed of the project is actually very fast, far exceeding the planned speed. However, despite the rapid expansion of the industry as a whole, many problems that exist will not be resolved quickly, which will result in great hidden dangers.

The development speed of wind power in Europe and the United States is relatively fast, and there are many experiences for Chinese enterprises to learn from. In fact, no matter which country, this area can be described as a sunrise industry. No country has fully mature experience. To this end, the entire industry must cooperate with each other to achieve a win-win situation in order to promote the progress of the entire industry.

Wind power is not a stable supply of energy and it is unrealistic to accurately predict the volume of wind. Moreover, the curve of wind energy is almost impossible to match with the curve of dissipation (acceptance, accommodation). How to effectively solve the stability of wind power supply?

Our country’s practice has always been to send wind power, hydropower and thermal power to the outside world. In other words, when wind power generation is launched, it is necessary to start thermal power or hydropower at the same time to adjust the stability of wind energy with a more controllable energy supply method. The more traditional approach is that each wind farm needs supporting other energy supply methods, which brings a problem, the cost is undoubtedly high, and it is also a serious duplicate construction.

The Kingdom of Windmills, which is also a powerful wind power kingdom, Denmark, has given us an approach worth thinking about. Denmark's own capacity for accommodation is limited, and it does not build a large number of hydropower and thermal power projects. Instead, it adopts hydropower and Germany's thermal power to regulate other countries in northern Europe.

The enlightenment of this kind of cross-national linkage approach to China is that the method of bundling and delivery is to completely evade the supply of energy to the provinces or regions of new energy power generation projects. The electricity-consuming region is just waiting for the arrival of stable energy. This is A narrow local protectionism.

Therefore, provinces with different advantages in energy should actively unite and take the form of sharing. The provinces with abundant thermal power and hydropower resources are responsible for the regulation and control of wind power generation projects above the national scale, so as to effectively reduce the problem of redundant construction of energy projects.

Moreover, this kind of cooperation should be more intelligent. At present, the United States is working hard to break through the federal system's limitations and build a high-voltage power grid across the state to make full use of different regional wind power output characteristics and share peaking power. This puts high demands on the power grid and the overall solution still needs to be led by the country for research and resolution.

It is the most important issue for China's wind power companies to face the difficulties of enterprise cooperation in order to win the Internet. The fundamental reason lies in the instability of wind energy and the difficulty of adjustment. Although technological breakthroughs are inescapable, how to quickly catch up with the advanced level in Europe and the United States, we still need to learn from the advanced experience of Europe and the United States - enterprise cooperation.

It must be made clear that the cooperation between enterprises must pay full attention to risk control, and the number of joint ventures in the wind power field in China is relatively large. In 2009, due to the impact of the financial crisis, many of the foreign investors of these companies were strongly affected. The Chinese wind power sector was once faced with the problem of foreign capital withdrawal. The fragility of the entire industry deserves attention. Taking IBM as an example, its Energy and Public Sector Department is working on technology research and development and cooperation in the new energy field. Cooperation partners are not limited to companies, and there are many cases of cooperation with scientific research institutions, and even cooperation with the national level. For example, in the island country of Malta, the country’s former power generation relied solely on imported fossil fuels. In order to ensure that the country could design a safe, environmentally friendly energy source at affordable prices, IBM and Malta’s State Power and Water Corporation cooperated to help They established the world’s first nation to establish a smart grid and fully integrate electricity and water systems nationwide.

The problem of difficulty in accessing the Internet is not due to the state power grid company’s monopoly on the right to speak, but it has not yet established enough smooth information exchange channels with power generation companies. In other words, the State Grid Corporation has also found it difficult to balance all companies. Especially for wind power generation companies, due to the predictability of their electrical energy, in order to protect the overall operation of the power grid, it is indeed difficult to put greater attention on these companies.

But this does not justify the lack of communication between companies. If there is a lack of enterprises involved in any one of them, the problem of wind power generation and internet access will never be solved. In addition, communication and cooperation between companies such as wind power equipment and power generation companies are also essential. Moreover, this cooperation does not have to be confined to China. For example, Sandwell International Engineering Group of Canada recently stated that it hopes to cooperate with enterprises in Fujian Province of China on wind power generation and other projects.

Application of smart grid technology With the gradual scarcity of global resources and increasing environmental pressure, the power industry is facing unprecedented challenges and opportunities. The power grid enterprises in many developed countries in Europe and America have generally regard the smart grid as one of the development goals of the future power grid. Chinese companies have also closely followed this trend.

At present, the existing smart grid technologies are mainly used in the field of power distribution and power consumption. The intelligence in the distribution field is to reduce the proportion of manual operations, and the application in this field is still very limited. The field of electricity consumption is mainly for home-installed smart devices. These equipments have small investment and obvious effects, and they have already been applied.

But now, the focus of people's attention has gradually shifted to the fields of power generation and transmission. One of the key points in this part is how new energy power generation projects can effectively intervene in the power grid.

In Europe, the power grids in countries such as Denmark, Germany, and Spain are very strong, and they are interconnected with neighboring countries through high-capacity, multinational links to ensure that new energy power generation projects in Denmark and other countries effectively enter the network. The United States is currently working hard to break through the federal system's restrictions and build a high-voltage power grid across the state to make full use of different regional wind power output characteristics and share peaking power.

Among these, an important aspect is to ensure the stability of wind power generation. There are two main programs that are responsible for regulating and controlling the advantages of traditional energy sources. The first is that these traditional energy bases provide each wind power base with a regulation scheme, and the other is to control the overall power grid on the premise of ensuring wind power and power generation. Sex to ensure the stability of the total power, and the overall distribution of the grid.

The latter solution is obviously of higher value for the stability and intelligence of the overall power grid, but it is very difficult to achieve, especially if there is a very large output difference in a short period of time. The difficulty is great. Therefore, it is still necessary to increase the investment in energy storage equipment so that it can ensure normal power supply effects as much as possible. The National Scenery Storage and Demonstration Project is currently underway in Zhangbei County, Zhangjiakou City, Hebei Province, and will be officially put into full application in the near future. Actively exploring the stability and controllability of wind power output power is one of the main objectives of this project.
