适应能源转型发展的输配电价动态激励机制研究

Dynamic Incentive Mechanism for Transmission and Distribution Tariff Considering Energy Transition Development

在能源转型的背景下,“重约束,轻激励”的输配电定价方式已不适应输配电网络低碳、安全、高效转型的发展需求。因此,该文设计了一种激励与约束相容的输配电价动态激励机制,研究表明:转型阶段下,需要进一步通过优化电网投资结构,减少投资冗余来提高输配电网络运营效率,电网仍是成本超支风险的主要承担者;省级电网的低碳、安全、高效之间的耦合协调程度整体呈现为逐年提升;所提激励机制兼顾差异性和公平性,有利于各省输配电网的清洁、低碳、可持续发展。

In the context of energy transition,the existing transmission and distribution(T&D)pricing method,which emphasizes being"constraint but not incentive",is no longer applicable to the demands of safe,low-carbon,and highly-qualified transformation development of T&D networks.Therefore,a dynamic incentive mechanism of T&D that compatible with the cost constraints is designed.The study shows that under the transformation stage,there is a need to further improve the operational efficiency of the T&D networks by optimizing the grid investment structure and reducing investment redundancy,and that the grid is still the main cost overrun risk bearer.The overall coupled-coordination degree between low carbon,safety and quality of each of the provincial grids in China is gradually increasing.The proposed incentive mechanism takes into account differentiation and fairness,and is conducive to the clean,low-carbon and sustainable development of each of the provincial T&D networks.
