China's Wind Power Development Path Should Take the Director of Europe and the United States (2)

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.

Smart grid should be more friendly

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.
