The world's smart grid competition has been fully launched. The major smart grid plans are the U.S. national unified smart grid, the European Union's super smart grid, and China's strong smart grid plan. In general, China's smart grid has a relatively large specificity and is quite different from other countries in the world.
The U.S. smart grid system is designed to meet the needs of traditional distributed energy systems under the premise of environmental protection and eco-friendliness. It uses intelligent networks to connect customer power sources, and also solves the storage of solar energy, hydrogen energy, hydroelectric energy, and vehicle electrical energy, including battery disposal. The system sells surplus electricity to the grid. At present, the smart grid construction in the United States has entered a steady progress phase under the policy encouragement and technology promotion.
Demystifying the best e-commerce platform mystery! Quotes may soon discover that the capital flow of major reversal institutions has undergone tremendous changes! The main funds are contemplating a new layout! The construction of the US smart grid is a crucial part of the Obama administration's new energy economy "rescue plan" . A total of more than US$15 billion was invested by the federal government, making the progress of US smart grids from technology R&D to demonstration projects more smoothly. In particular, in August 2008, Bordeaux, Colorado, completed the first phase of the smart grid project and became the first city in the United States to have a smart grid.
In order to meet the electricity needs of the Mediterranean region and continental Europe, the European Union proposed the idea of ​​building a super smart grid in 2007. In early 2009, the European Union clearly stated that the offshore wind power in the North Sea and Atlantic Ocean, solar energy in southern Europe and North Africa will be integrated into the European power grid through the smart grid. The European North Sea countries, represented by Britain, France and Germany, formally formulated in 2010 an ambitious plan to jointly build a renewable energy super power grid, which will link wind power generation in Scotland, Belgium and Denmark, solar panels in Germany and hydropower plants in Norway. One, this is a key step towards realizing the commitment of the European Union to increase the proportion of renewable energy in the energy supply to 20% by 2020.
Observing the European and American smart grids, we can see that the common ground between the two is that they focus on large-scale development and utilization based on the smart grid construction on the distribution and transmission side and renewable energy generation, and make full use of different areas. The regional load differentials, which are offset by peaks, peaks, and fire and water, with gas-fired power stations, conventional hydropower stations, and pumped-storage power stations, have overcome the randomness and incoherence of renewable energy generation.
Comparing with Europe and the United States, the current driving force of China's construction of a smart grid is mainly to meet the needs of electric loads, protect the environment, effectively solve the problem of large-scale, long-distance, and low-loss transmission of electric power, and provide a better platform for the concentration and dispersion of co-existing clean energy power. Enhance the power grid's ability to accept clean energy.
The three stages of the overall development of China's smart grid proposed by the State Grid, formally announced that China has also entered the ranks of the global smart grid competition. As early as 2007, East China Power Grid Corporation launched a smart grid feasibility study project, and then launched smart grid pilot projects such as advanced dispatch centers and unified information platforms. In 2008, the North China Power Grid Corporation devoted itself to building intelligent dispatching systems and establishing smart grid information architecture as its main body to carry out research and construction of smart grid-related technologies.
At this stage, China's smart grid construction is different from Europe and the United States, at least the strong smart grid with the UHV grid proposed by the State Grid. The corresponding engineering practices are mainly UHV AC/DC transmission demonstration projects and smart grid pilot projects. At present, based on basic considerations, project feasibility, demonstration effects and other aspects, nine projects have been selected as the first pilot sites, of which the Shanghai World Expo Park Smart Grid Integrated Demonstration Project is the first representative engineering practice.
We are looking forward to building a smart grid with Chinese characteristics. However, this particularity also makes China may face some special problems in the process of building a smart grid.
1. The smart grid built by China integrates intelligence into UHV transmission, which is different from the smart grids of Europe, the United States and Japan. At present, the United States, Japan, and other countries have established strategic network commands for power networking. The key is to maintain the stability of the smart grid and respond to future security issues. Then, the security threats of our country's system that combines UHV and smart grids, and how to deal with them once they are attacked, are questions that need to be carefully evaluated.
Second, the installed capacity of renewable energy power generation has grown rapidly. However, domestic research and solutions for the integration of renewable energy power generation are lagging behind.
Third, intelligent user hardware devices and software configuration to enable them to interact with the grid, still need a long time of research and development and practice.
Fourth, in addition to technical difficulties, the profit model may be the key issue. The huge investment in smart grids, how to find the right profit model, and achieve a win-win situation among power companies, equipment manufacturers, service providers, and power users, will become the decisive factor in the promotion of smart grids.
It is true that these problems can be solved, but they need constant exploration and innovation. It can be said that the main difference between the situation in China and Europe and the United States lies in the distribution of resources. The relocation of foreign power terminals to the power distribution terminal and the backward push to the smart grid development strategy may not be suitable for China. The combination of smart grid and UHV may be possible. It is a relatively clear Chinese feature. However, we must also learn from international experience and lessons learned, such as smart grid support for distributed energy, because distributed is one of the future ways of renewable energy in China. In addition, similar to Europe and the United States emphasizing the user-side smart power, improving the user-side power efficiency, so that electricity service more quality, which is also the focus of China's smart grid development.
The standard issue is a recognized hurdle for the development of smart grids. The competition for standards development mainly exists in two aspects. One is the issue of access, and the other is the issue of equipment standards. The grid company as the standard formulation participants, the release of standards is still only at the enterprise level, if you want to rise to national standards, you also need more participants to improve. The current development of grid companies in the field of equipment has indeed raised some concerns about conflicting standards.
Finally, from the development history of smart grids in Europe and the United States, the profit model is the focus of attention, and it is a key issue for China. The construction of smart grids in Europe and America has highlighted market operations and service innovations, and there have been some successful cases. Relatively insufficient domestic marketization, it is extremely important to seek a better smart grid profit model. It is the basic driving force for the rapid spread of smart grids.
The energy consumption per unit of many domestic companies is still relatively high compared to the world's advanced level, with a large space for energy conservation, and effective control of energy consumption can play a role in peaking and filling the grid. Driven by the government's renewable energy policy and energy saving policy, the smart client technology of large consumers may be relatively easy to accept, thus forming a rapid development path.
