摘要
水电具有能源可再生、大规模储存、跨时空调节、综合性利用等特征,并且运行成本低、环境污染小。但是,目前老旧水电缺乏价格调整机制、价格与容量成本联动性不强、环境效益体现不充分,导致水电上网电价无法反映水电真实价值。在此背景下,以四川省为例,首先剖析了水电发展状况及指出了水电外送中倒推价偏低等一系列问题,提出了相应解决方案。然后,将落地省煤电基准价倒推扣减输配电价,提出外送水电竞争力分析方法,并与水电上网电价进行比较。并基于容量补偿和绿电价值,提出了上网电价测算模型,真实反映水电容量成本和环境价值。最后,在测算四川省外送水电竞争力的前提下,选取某水电站测算两种电价机制,为水电上网电价调整提供了依据。
Hydropower has such characteristics as renewable energy,large-scale storage,cross space-time regulation and comprehensive utilization,low operation costs and low environmental pollution.However,at present,a lack of price adjustment mechanisms for old hydro⁃power,the weak linkage between price and capacity cost,and the inadequate embodiment of environmental benefits have led to the inability of hydropower feed-in tariffs to reflect the true value of hydropower.In this context,taking Sichuan province as an example,this paper firstly analyzes the hydropower development and points out a series of problems such as low backward pricing in hydropower outward transmission,and proposes corresponding solutions.Then,the benchmark price of coal-power in the landed province is backwardly deducted from the transmission and distribution price.A competitive analysis method for outward hydropower is proposed,which is compared with hydropower feed-in tariffs.And based on the capacity compensation and green value,a feed-in tariff measurement model is proposed to truly reflect the capacity cost and environmental value of hydropower.Finally,on the premise of measuring the competitiveness of outward hydropower in Si⁃chuan Province,a hydropower plant is selected to measure two tariff mechanisms,which provides a basis for the adjustment of hydropower feed-in tariff.
