摘　　要：随着多能交互和联合优化运行的日益增加,分解协调等分布式优化算法由于可保护市场主体的隐私以及自身调度权而得到了广泛关注。然而,现有分解协调算法在用于支撑多能优化运行时面临两个挑战:多能协同涉及多种能源、多个市场主体,通常不存在现成的协调中心;此外市场主体可能通过不遵守分布式优化算法的方式,在获得不当利益的同时损害整体利益。为解决以上挑战,该文提出了基于区块链共识算法的可信多能协同技术,聚焦于模型与算法。该文首先介绍了多能协同优化运行的模型及相应的分解协调算法。随后,通过市场主体作恶的案例说明可信协同技术的必要性,并提出基于共识算法的可信协同技术架构与具体流程。其思路是引入多个市场主体共同担任分解协调算法的协调级,以解决多能协同时无现成协调级的挑战;并增加协调者间的共识环节,以抑制可能的市场主体作恶行为。最后,论证所提可信协同技术的安全性、容错性、一致性。With increasingly interaction and co-optimization of multi-energy systems,distributed algorithms such as decomposition and coordination algorithms have gained popularity because they can protect privacy and enable autonomous operation of participating entities.However,two challenges arise when using existing distributed algorithms to solve multi-energy optimization problems.On the one hand,multi-energy co-optimization involves various energy resources and multiple entities,thus there usually does not exist a coordinator.On the other hand,some entities may disobey the setups in existing distributed algorithms,compromising overall interests for personal gains.To this end,this paper proposed a trusted multi-energy co-optimization technology based on a blockchain consensus algorithm,which was the first part of the series of papers,focusing on the modeling and algorithm.This paper first introduced the model of multi-energy co-optimization and the decomposition and coordination algorithm.An example showed the necessity of trusted co-optimization.The architecture and procedure of the trusted co-optimization technology based on blockchain consensus were then proposed.The core idea of the technology was to select multiple entities as the coordinator in case that no coordinator exists to run distributed algorithms or enforce consensus algorithms to mitigate potential malicious behaviors.Finally,the security,fault tolerance,and consistency of the proposed method can be verified.
