摘　　要：随着大用户直购电的逐步开展,有必要分析其对清洁能源发展的影响。对大用户交易电量需求与火电成本进行了分析,研究了不含直购电的大用户交易均衡状态,并在发电侧垄断和非垄断的大用户直购电情况下分析均衡状态。在均衡状态下,进一步计算火电企业的平均利润率,分析开展直购电前后的变化情况,结果表明,开展直购电后火电企业的平均利润率有所降低。在清洁能源全额消纳的政策要求下,分析清洁能源的利润率。然后对比开展大用户直购电前后火电和清洁能源的平均利润率及其关系。通过比较分析,发现大用户直购电不会对清洁能源发展造成长期的负面影响。打破地区发电侧垄断,并制定好清洁能源的售电电价,非直购电情况下火电售电价格和大用户购电价格以及大用户直购电情况下的过网费等是促进清洁能源发展的关键因素。With the development of the direct power-purchase of large users, it is necessary to analyze its impact on the development of clean energy. This paper analyzes the quantity need of the direct power-purchase for large users and the cost of thermal power, researches the equilibrium states of large users＇ transactions without direct power-purchase, and analyzes the equilibrium state under direct power-purchase of large users with or without power generation monopoly. We further calculate the average profit rate of thermal power enterprises under the equilibrium state, and analyze the change of these rates before and after the direct power-purchase development. The average profit rates after the direct power-purchase development of thermal power enterprises are lower than before. In the full consumptive requirements of clean energy, this paper analyzes the profit rates of clean energy, and then compares the average profit rate and relationship of thermaI power and clean energy before and after allowing direct power-purchase of large users. Through the comparison and analysis, the direct power-purchase of large users won＇t have long-term negative impact on the development of clean energy! Breaking the monopoly of regional power generation side and making appropriate prices of clean energy sale, thermal power sale and large users purchase without direct power purchase and wheeling cost with direct power purchase are key factors for promgting clean energy development.
