Abstract:

The current subjectively fixed performance guarantee quota model lacks objectivity in the cost calculation of performance guarantees for power-selling companies, which affects transaction decisions. Therefore, this study proposes a medium- and long-term transaction optimization decision-making model for power-selling companies based on a dynamic performance guarantee quota. First, a quota adjustment coefficient was proposed, considering the credit overdraft level, market loss level, and national policy inclination of the power-selling company. Subsequently, a dynamic performance guarantee quota model was constructed. Second, to maximize the profits of power-selling companies, a medium- and long-term trading optimization decision-making model was constructed, considering the impact of changes in the cost of performance guarantee on the trading decisions. This model incorporates the dynamic adjustment of the performance guarantee quota. Finally, by analyzing the dynamic and fixed performance guarantee quota, performance guarantee costs, and transaction profits of power-selling companies participating in medium- and long-term transactions under multiple scenarios, the suitability and effectiveness of the proposed optimization decision model for the medium- and long-term transactions of power-selling companies based on the dynamic performance guarantee quota were verified.

Key words: power selling company, dynamic performance guarantee quota, quota adjustment coefficient, medium- and long-term transaction optimization decision-making
