The first section in your paperThe impact of the development of the Energy Internet on power grid companies
Energy Internet realizes the deep integration of Internet innovation elements and traditional energy industry. The integration of Internet technology and the penetration of Internet spirit have also injected new power elements into the energy industry. The development of the energy Internet has brought major changes to the production, transmission and consumption of energy systems.

Energy production is more low-carbon
Building a clean, low-carbon, safe and efficient newgeneration energy system and realizing energy transition are the core goals of the new round of energy revolution [1] . With the increasing impact of global warming and environmental degradation, large-scale development and wide-area deployment of clean energy have become the consensus of all countries, which is the only way to promote world energy reform. Replacing fossil energy with renewable energy on the power generation side is a more fundamental transformation goal for achieving a green economy, and emission reduction commitments have made China one of the main drivers of the global "renewable energy substitution"

Energy transmission is more intelligent
With the application of advanced power electronic technology and information and communication technology, the flexibility and reliability of energy transmission will be further improved, making energy transmission more intelligent and automated [2] . Efficient energy transmission requires timely absorption of renewable energy with intermittent, sudden and other characteristics, as well as monitoring and other computing equipment that control energy flow and adjust energy types to meet consumer demand. The integration of advanced information and communication technologies and the power sector will have an impact on energy transmission in terms of technology, form, and function.

Energy consumption is more diverse
The energy Internet allows consumers to fully meet their individual needs. With the development of the energy Internet, consumer needs tend to be diversified, and the interaction with grid companies will be further strengthened. On the energy consumption side, the changes in the focus of energy consumers are mainly as follows: Energy consumers want products and services to become simpler. Fast, simple, and easy services have become the most important requirements of global energy consumers for energy companies. Energy consumers want a seamless user experience, including the same service experience in different channels, easy E3S Web of Conferences 185, 02002 (2020) ICEEB 2020 http://doi.org/10.1051/e3sconf/202018502002 transaction processes, and convenience in different channels Switch. Consumers expect energy companies to provide personalized services based on user insights.
From a global perspective, the sharing of personal information and the advancement of big data processing technology have promoted the development of personalized service models, and consumers have higher and higher expectations for personalized services. Personalized services based on user behavior prediction are becoming more and more important. At the same time, the security of related data and the protection of user privacy have become the focus of consumers' concerns. To make energy consumption meaningful, "electricity" is not only "electricity", but also represents values. From a global perspective, "value beyond commodities" has become the focus of consumers' energy consumption. Consumers pay more attention to saving energy consumption expenditures, and are more interested in energy-saving products and energy products and services with renewable energy subsidies.
Information sharing and resource sharing have become a trend. From a global perspective, consumers' information sharing and resource sharing give users greater bargaining power and enable them to enjoy services without purchasing assets.

Changes in the development model of power grid enterprises
Energy Internet is a new form of energy industry development that deeply integrates the Internet with energy production, transmission, storage, consumption and energy markets. It is a comprehensive upgrade of the traditional power grid and will affect the development concept, corporate functions, technical characteristics, and business of grid companies. The scope, development model and other aspects have brought about comprehensive improvements and changes [3] [4] .
In terms of development concept, it is changing to openness, interaction and sharing. Compared with the relatively closed development concept of traditional power grids, grid companies in the future will adopt a more open attitude to serve the diverse needs of users, promote market opening, and create a win-win ecosystem.
In terms of corporate functions, it has shifted from traditional grid business to a more comprehensive platform ecological business. In the future, the function of power grid enterprises will promote the creation of an efficient energy market through mechanism and format innovation.
In terms of technical characteristics, the transformation from traditional large-scale grid technology to strong smart grid and Internet of Things technology. With the high proportion of new energy sources, the widespread use of a large number of power electronic equipment, the increase in the scale of AC and DC hybrid power grids, and the application of information technology such as the "big cloud and mobile smart chain", the physical form and operation mode of the power grid will fundamentally change.
In terms of business scope, it has transformed from a single power supply business to multiple businesses such as integrated energy services and value-added services. In the future, the business scope of power grid companies will focus on user needs to develop integrated energy services such as multi-energy complementation, energy-saving transformation, equipment operation and maintenance, water, electricity and heating, as well as platform services such as Internet of Vehicles and energy storage cloud network. At the same time, develop valueadded derivative services such as big data credit investigation and advertising.
In terms of the development model, it has shifted from a power supply company to an energy ecological core company. In the future, power grid companies will focus on energy supply, gather energy producers, transmitters, consumers, equipment vendors, service providers and other diversified entities to create an energy Internet ecosystem of co-construction, governance and sharing.
