In addition, in the underground garage, there are also 6 electric vehicle charging piles to meet the intelligent charging needs of residents in the community

228 items of smart electricity in 21 categories

pilot project exploration and promotion

since the development plan of smart electricity was first announced to the society in May 2009, NEC has carried out the construction of 228 smart electricity pilot projects in 21 categories in 26 provinces and cities, with the goal of basically building a strong smart electricity by 2020

at the second China (Wuxi) new energy conference held not long ago, jiangliping, vice president of the National Energy Research Institute, revealed that NEC hopes to promote some mature and successful smart electricity pilot practices on a large scale before 2015, when 2 unloading steel strand and other samples

she said that smart electricity has indeed received the attention of the government, and relevant enterprises have also invested a lot. However, no country has yet achieved the strategic planning at the home level of the relevant functions of the electronic universal experimental machine. At present, it is still being promoted step by step under the framework of the State Grid Corporation of China

so far, we have implemented two batches of pilot projects, and are analyzing and evaluating the implementation effectiveness of the first batch of projects. On the basis of summarizing the evaluation results, we should promote and apply some mature and successful practices on a large scale before 2015. From 2015 to 2020, it is the stage of national construction. We hope to initially build smart electricity around 2020. Jiang Liping said

she also revealed that the national energy administration also specifically listed a topic "Research on the development mode of smart electricity in China" in the 12th Five Year Plan of energy, but this topic has not been officially concluded yet. The next step, from the national level, remains to be seen

the current smart electricity

has a strong UHV color

although the development of smart electricity in China continues to advance, some experts pointed out that under the current system in which smart electricity construction is led by power companies, the national smart electricity strategy has a strong UHV color. Due to differences in national conditions, the development of smart electricity is different. The core and foundation of smart electricity abroad is distributed energy, but China's smart electricity focuses more on the transmission side, emphasizing strong smart electricity under UHV architecture

at present, the focus of developing smart electricity abroad is not to continuously improve the voltage level, but to give priority to the development of more efficient and energy-saving distributed energy systems. China's smart power focuses more on the transmission side, emphasizing the strong smart power under the UHV framework. Hanxiaoping, chief information officer of China energy, said

according to Han Xiaoping, there is a solid foundation and real market for the development of smart electricity in the United States, Europe and Japan, that is, the distributed energy system gradually developed since the oil crisis in the 1970s. The development of smart electricity abroad is to provide a free access dynamic platform for all kinds of distributed energy, an intelligent control and management platform for energy conservation and demand side management, and an innovative application platform for electric storage vehicles and various new electrical appliances, so as to solve the problems of power supply safety and sustainable development. Just like many PCs form local areas, many distributed energy forms micro electricity, which needs to be connected with the main, so an intelligent management system is needed, and smart electricity comes from it

but in China, the definition of smart electricity by State Grid Corporation of China is: strong smart electricity with UHV as the backbone, based on the coordinated development of all levels of electricity, and characterized by informatization, digitization, automation and interaction

Hu Zhaoguang, vice president of the National Energy Research Institute, explained that by 2020, the national power will face the transmission problem of 150million kW wind power, and will focus more on the transmission side, which is determined by China's economic development stage and the characteristics of energy concentration and distribution. After all, China's national conditions are different from those in the West. Distributed energy cannot become the foundation and mainstream of smart electricity

Zhou Yuanbing, deputy chief engineer of the National Energy Research Institute, stressed that the development of distributed energy in national electricity is always based on the consideration of the transmission side and the distribution side, but the consideration should also be focused at different stages. At present, the primary task of developing smart electricity is to solve the problem of large-scale transmission of renewable energy. Due to the lack of the foundation of distributed energy in China, smart electricity is the first to develop the transmission side. With the development of distributed energy, smart electricity will definitely be popularized to the distribution side in the future
