(1) With the continuous and extensive access of distributed power sources, power dispatching and optimal control will become more complicated, and the interaction and cooperation between power supply enterprises and power users will become closer. (2) In the traditional supply and demand market composed of power supply enterprises and power users, there will be third-party entities such as virtual power plants, distributed photovoltaics and charging and replacing cars, thus completing the change of the original market order. A large number of power sales companies will flood into the power sales market, and power supply companies will face the risk of being "pipelined". (3) With the establishment of the power trading center, the pricing function, trading function and data service function of the power trading market will be continuously improved, and the competition will be more diversified and fierce. (4) An efficient and linked three-dimensional demand management mechanism will be established between power grid and users, power grid and power selling enterprises, power selling enterprises and terminal producers and sellers. (5) Manage the power market with more efficient information. With the strong support of communication and information technology, the power market will realize information sharing, facility sharing, instant collaboration and intelligent decision-making. Third, the analysis of competitive advantages and disadvantages of power supply enterprises At present, more and more enterprises are involved in power business, such as BYD in distributed energy; Communication companies and Internet companies such as Huawei, ZTE and Xiaomi will also participate in emerging businesses. Compared with these competitors, the advantages of China's power supply enterprises are mainly reflected in the huge customer base, rich experience in power grid technology and high-quality power professionals. But at the same time, we also have some problems, such as the immature application of emerging technologies such as the Internet, too many restrictions on the existing institutional processes, and the slow transformation of enterprises. Table 1 comparison of advantages and disadvantages between power supply enterprises and competitors; Accumulate rich power grid technology and experience; Knowledge accumulation of employees' power marketing service. The scale of the enterprise is huge and the transition period is long; The application of emerging technologies such as the Internet is not mature enough; The business model is not flexible enough and has limitations. Stable energy supply of power generation enterprises; Rich data accumulation; Strong technical research and development strength; Customer channels are stable. Sensitivity is not enough; Lack of innovation in business model; Weak sense of competition. Internet companies have rich service channels; Strong innovation ability of service model; The information depth is wide. Lack of knowledge of power products; Weak technical experience in power industry; Technology research and development ability is weak. Fourth, the development and promotion strategy of power supply service (1) strengthens the concept of full-time, whole-process and whole-hearted service. Actively promote the construction of customer service system, constantly improve the power grid structure, and improve the power supply support capacity; Continuously improve the reliability of power supply and improve the level of power quality; Pay attention to customer needs and continuously improve customer relationship management ability. It is necessary to further strengthen the awareness of full service within power supply enterprises, change the traditional "waiting for customers to come to the door" into "taking the initiative" and actively go out. Through the collaborative service of various professions, we will do a good job in the whole process service before, during and after the electricity consumption of customers, and enhance the reputation and reputation of enterprises. (2) Strengthen service brand building and cultivate loyal customers. Service brand is the long-term accumulated customer reputation of enterprises and the soft power of enterprises in the face of fierce social competition. Power supply enterprises should establish brand and product awareness, learn from the experience of brand packaging and brand operation management in other industries, constantly integrate and upgrade power supply service brands, update and upgrade power supply service products, strive to gain customer recognition and dependence, and gradually cultivate valuable customer groups. (3) Pay attention to service cost control and improve profitability. Identify customer needs, provide services that customers really need, and avoid excessive service and waste of resources. Through the research and application of marketing big data analysis, combined with different types and groups of customers' electricity demand, habits, value, influence and other factors, targeted service strategies are formulated. On the basis of ensuring universal electric power services and personalized differentiated services, we will integrate service channel resources, optimize the allocation of physical business halls, promote remote service channels such as WeChat, Web Hall and Palm Hall, and low-cost service methods such as bank electricity deduction, and strive to achieve a reasonable balance between enterprise costs and operating profits. (4) Optimize process rules and improve business convenience. Through benchmarking, CLP Power customers in Hong Kong can quickly adopt humanized measures for all power consumption businesses with their ID cards, and further streamline business processes, so that the business process setting of power supply and consumption can not only meet government requirements, reasonably avoid business risks, but also enhance business convenience and enhance customers' subjective perception experience. (5) Promoting scientific and technological innovation and enhancing talents and technological advantages. Strengthen scientific and technological innovation of power marketing, apply cutting-edge technical means, and provide information platform support for business and on-site service. Strengthen meter management, strive to provide a transparent, fair and safe trading environment for both power suppliers and users, and provide strong technical support for the investigation and evidence collection of power theft cases and power recovery. Power supply enterprises also need to rely on the technical advantages of electric power to establish scientific research and training bases, cultivate professional and technical personnel, and enhance the advantages of talent and technical resources of power supply enterprises.
