2、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。关键词:大用户;直购电;清洁能源;利润率;均衡状态-ImpactAnalysisofDirectPower-PurchaseofLargeUsersonCleanEnergyDevelopmentYANJinghua,CUIHui,HANBin,LIUFang,LIXiao
