基于博弈策略的能源区块链安全交易机制

能源区块链的先期探索给能源互联网的建设提供了良好的技术支撑,然而大规模参与主体的不断涌入,能源交易的安全、公平、效率等问题再次迎来新的挑战,博弈论因考量了交易主体之间的策略互动及利益依存关系,有望为该问题的解决提供新思路。首先,以能源交易的利益最大化为目标函数,构建多能源交易策略的博弈模型,依据能源供需量及报价,求解能源用户和能源商户策略博弈的纳什均衡值,为交易机制提供价格参考。其次,结合能源互联网的特性,构建基于联盟链的弱中心化多主体能源交易机制,并对能源区块结构及共识机制进行改进以实现高效可靠的交易流程。最后,在模拟场景下进行算例仿真,仿真结果表明所提出的安全交易机制在保障买卖双方利益的同时,加快了区块的共识速度,为能源交易平台的建设提供帮助。

Security Transaction Mechanism of Energy Blockchain Applying Game Strategy

The early exploration of the energy blockchain has provided good technical support for the construction of the energy internet. However, as the continuous influx of large-scale participants, the safety, fairness and efficiency of energy transactions once again face new challenges. Game theory considers the advantages of strategic interaction and interest dependence between transaction subjects, and is expected to provide new solutions. Firstly, the objective function of maximizing the benefits of energy trading is to construct a multi-energy trading strategy game model. According to energy supply and demand and quotation, the Nash equilibrium value of the strategy game between energy users and energy providers is solved, which provides a price reference for the trading mechanism. Combining the characteristics of the energy internet, this paper builds a weakly centralized multi-agent energy transaction mechanism based on the alliance chain, and improves the energy block structure and consensus mechanism to achieve an efficient and reliable transaction process. Simulation results show that the secure transaction mechanism not only protects the interests of buyers and sellers, but also speeds up the consensus of the block, with a view to provide help for the construction of the energy trading platform.
