AI Technical Summary

Problems solved by technology

For small and medium power users, it is also difficult to find and replace a suitable power sales company agent

[0008] (2) In bilateral negotiations, the right of speech and bargaining power of market players is greatly affected by the capacity of their market players, which means that the market competitiveness of small-capacity power generation companies, electricity sales companies and power users is relatively weak
