Abstract: With the deepening of the reform of the power system and the improvement of the market mechanism, power supply enterprises are facing a complex and changeable business environment and increasingly fierce market competition. This paper analyzes the challenges faced by power supply enterprises in power marketing management, including the impact of new energy, the diversification of user demand, and the inefficiency of electricity fee collection. In view of these challenges, this paper proposes a series of implementation strategies for power marketing management, including the application and optimization of smart metering technology, the implementation of demand response technology, the analysis of customer electricity consumption behavior, and the application of electricity market trading technology. The results show that these strategies can effectively improve the marketing management level and enhance the market competitiveness of power supply enterprises. Through case analysis, the feasibility and effectiveness of the proposed strategy are verified, and the theoretical basis and practical guidance for power supply enterprises to optimize power marketing management are provided.
