摘　　要：以电力市场供不应求为前提,结合我国流域梯级电站上网电价机制的特点,从流域电站发电量、上网电价与利润三项经济指标之间关系的角度,建立以全流域利润最大化为目标的电价机制分析模型。结合实际数据,比较统一电价与一站一价两种电价机制下流域总发电量和总利润,并通过分析单位发电量利润的变化规律,讨论统一电价机制的可行条件。为流域公司决策和经营部门参与政策制定和市场报价提供参考依据。A pricing model for profit maximization was established to analyze the unified electricity price of cascade hydropower stations after considering the relationship between power generation,price and profit and supposing a short supplying electricity market.In a case study,the total power productions and profits of cascade hydropower stations were calculated under unified pricing and individual pricing system respectively,and the margin change of profit was also analyzed.The results show that the utilization of unified pricing system is necessary and feasible for a hydropower generation enterprise.
