摘　　要：现行人为主观给定的固定履约保函额度模式导致售电公司履约保函成本测算缺乏客观性,影响交易决策。为此,提出了一种基于动态履约保函额度的售电公司中长期交易优化决策模型。首先,提出考虑售电公司信用透支程度、市场流失程度和国家政策倾向的额度调整系数,并构建动态履约保函额度模型。其次,考虑履约保函成本变化对售电公司交易决策及利润的影响,以售电公司利润最大化为目标,构建了计及履约保函额度动态调整的中长期交易优化决策模型。最后,通过分析多个场景下售电公司参与中长期交易的动态和固定履约保函额度、履约保函成本和交易利润,验证了所提出的基于动态履约保函额度的售电公司中长期交易优化决策模型的合理性和有效性。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 longterm 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.
