基于区块链技术的非合作博弈共享储能交易模型

Non⁃cooperative game trading model for shared energy storage based on blockchain

针对目前储能成本过高、缺乏交易平台导致的利用效率低下、收益较低等问题,设计基于区块链技术的非合作博弈交易模型.以微网作为节点引出共享储能的概念,利用数字签名技术进行节点身份验证,有效提高交易的安全性.基于智能合约自我驱动、自我执行的特征,建立共享储能交易机制.通过建立非合作博弈模型,实现各节点利益最大化,提高储能收益,提高节点用户参与交易的积极性,推动产业结构进一步优化.算例分析结果表明,本文所提出基于区块链技术的共享储能非合作博弈交易模型可以有效实现储能参与市场交易,提高储能利用效率,增加储能项目收益来源,为储能行业的进一步发展提供有效的技术支持和理论支撑.

The energy storage is perplexed by low utilization efficiency and poor profit due to its high cost in energy storage and lack of trading platform.Here,a non⁃cooperative game trading model based on blockchain is designed for shared energy storage.Taking microgrids as nodes,shared energy storage uses digital signature to verify node identi⁃ty,which can effectively guarantee the transaction security.The trading mechanism for shared energy storage is es⁃tablished on the self⁃driven and self⁃executing smart contract.The non⁃cooperative game model can maximize the benefits of each node,improve energy storage profit,and motivate the node users to participate in transactions,thus help optimize the industrial structure.Example analysis shows that the blockchain⁃based non⁃cooperative game trading model can effectively realize participation of energy storage in market transactions,improve energy storage utilization efficiency,increase energy storage profit,and provide technical and theoretical support for further develop⁃ment of energy storage industry.
