能源互联网背景下中国光储价值链效益协同模型研究

Research on the Benefit Synergy Model for the value chain of photovoltaic and energy storage in China under the background of Energy Internet

摘要:

本文针对光伏发电存在的随机性、波动性等特点引入储能及能源互联网建立了能源互联网背景下的光储价值链,并以光伏发电商与储能商组成的二级价值链为研究对象进行了光储价值链效益协同模型研究。文章首先对逐对比较法进行了改进以确定链条节点的双重努力因素,其次分别构建了分散价值链Stackelberg博弈模型、集成价值链模型,再次在分散价值链的基础上引入收益分享与努力成本共担联合契约(RSECP)以及回购与努力成本共担联合契约(BECP),最后通过数值分析进一步验证了上述模型的有效性。结果表明,集成价值链模型表现优于分散价值链模型,而在分散价值链中引入两种契约后能在保证节点企业利益的基础上实现价值链整体利益最大化,有利于光储价值链的效益协同。

Abstract:

Based on the randomness and volatility of photovoltaic, this paper introduces energy storage and Energy Internet to establish the value chain of photovoltaic and energy storage, and studies the benefit synergy model of the constructed secondary chain consisting of photovoltaic power generation company and energy storage business. First, the pairing comparison method is improved to determine the double effort factors of node enterprises in the chain. Then, the Stackelberg model of decentralized value chain and the model of centralized value chain are constructed. Next, two joint contracts of Revenue Sharing and Effort Cost Participation (RSECP) and Buyback and Effort Cost Participation (BECP) are introduced into the decentralized value chain to coordinate the benefit. Finally, the effectiveness of proposed models is validated by the case study, which indicates that the decentralized value chain performs better than the centralized value chain. Meanwhile, RSECP and BECP can maximize the overall benefit of the decentralized value chain when ensuring the benefit of the node enterprises, which is conducive to the benefit synergy for the value chain of photovoltaic and energy storage.
