风光储项目价格机制及经济性分析

现有可再生能源价格机制和补贴政策是否能够继续适应并满足可再生能源的科学发展,是一个亟待研究、总结和反思的问题。分析风光储项目技术选型及造价,选取典型风光储项目,分析现行风光储电价政策的适用性,并对可能的核价方式进行探讨,对不同定价方式下项目的经济性进行分析,并采用敏感性分析法量化了造价和电价对项目经济性的影响,提出风光储的定价机制：短期内可以采用整体定价模式予以核价;长远来看,为保证价格政策的激励性,促进公平和提高效率,风光储项目宜分开定价,出台单独的储能电价政策。

Pricing Mechanism and Economic Analysis of Wind-PV-ES Hybrid Project

In this paper, the selection of technical solutions and the cost of Wind-PV-ES hybrid project are analyzed. The applicability of the existing tariff policy for the selected typical Wind-PV-ES hybrid project and the feasible pricing methods are discussed. Besides, the project's economy under different pricing methods is investigated and the influence of construction cost and electricity pricing on the project's economy is quantitatively analyzed by using sensitivity analysis method. The pricing mechanism for Wind-PV-ES hybrid project is also proposed. From the results, it can be concluded that package pricing can be used to the whole project in short term. While in long term, in order to ensure the price policy's incentive and promote fairness and efficiency, separate pricing should be used for the Wind-PV-ES hybrid project and the energy storage price policy should be introduced.
