The COVID-19 pandemic has significantly affected the energy sector. The new behavior of industrial and non-commercial consumers changes the energy consumption model. In addition, the constraints associated with the coronavirus crisis have led to environmental effects from declining economic activity. The research is based on evidence from around the world showing significant reductions in emissions and improved air quality. This situation requires rethinking the energy development strategy, particularly the construction of smart grids as a leading direction of energy development. Evaluating the efficiency of smart grids is a vital tool for disseminating successful experience in improving their management.

As a key part of the power system, the substations undertake important work. With the development and construction of smart grids, the status data, image monitoring data, and environmental meteorological data of power systems are gradually being integrated and shared on a unified platform. Traditional models based on theoretical analysis are difficult to deal with multi-dimensional, massive data set information. Under this background, starting from the inherent law of the data itself, the use of machine learning methods combined with the infrared image data of the equipment can achieve intelligent identification and early warning of substation equipment failures. This paper first uses the convolutional neural network to identify the substation equipment in the picture, and then combines the infrared image to perform image registration. Finally, the deep belief network is used to determine whether the device is in wrong condition. The overall substation equipment fault identification is tested on real data, and the experimental results show that the proposed method has high accuracy.

Smart grids are smart grids because they don't only transport electricity but also information that will become an active part of the electricity supply system.

The promise of smart grids is very attractive. However, it is not yet clear what the future smart grid will look like. Although most researchers acknowledge that users will play a more prominent role in smart grids, there is a lot of uncertainty on this issue. To counter the strong technological bias in smart grid research and literature, we propose that research should focus more on the social and business dimension of smart grid developments. The main elements of such a research agenda are: Developing more socially embedded visions on smart grids and the services it will provide A shift in the focus on developing smart grids components and systems towards the services it will deliver Development and testing of innovative user-centered business models and ecosystems. More general, on the role of users in smart grids, the main lesson is that user roles should be taken more seriously in relation to smart grids: experts should no longer regard users exclusively and/or simply as potential barriers to smart grid innovation but also as important stakeholders and potential participants in the innovation process.

With the planning and implementation of national smart grid construction, on-line monitoring technology, as one of the key technologies of smart transmission, is also developing towards intelligence. With the construction of smart grid, the number of UHV long-distance and large-capacity transmission lines is increasing, and the load density of the grid is also increasing. As an important component of power system operation, the safety and reliability of power lines are very important. At the same time, with the popularization of helicopter inspection of power transmission lines, it not only provides opportunities but also challenges for automatic detection of defects in power transmission lines by image processing and recognition technology. How to effectively obtain basic information of power line operation from power line images obtained by helicopter inspection has become a research hotspot. Using automatic extraction method of image recognition can not only improve work efficiency and detection accuracy, reduce patrol personnel, but also overcome various defects of manual methods, and finally improve the safety of power line patrol and the accuracy of detection results.
