摘　　要：为保障区域综合能源系统(integrated community energy system,ICES)中多元能源主体的信息安全与涉密隐私,满足终端用户电/热等多维度用能需求,提出了一种面向ICES的分布式优化调度方法。首先,分别对ICES中配电系统、配气系统及耦合系统进行建模,并采用合适的数学方法对模型进行线性化处理;其次,以系统运行成本最小化为目标,通过引入共识变量实现对ICES优化调度问题解耦,并给出适用于ICES多元能源主体接入的分布式优化调度算法;最后,采用一个典型的ICES算例对所提方法进行验证。结果表明,基于文章所提方法得到的优化调度方案与采用集中式优化调度方法所得方案一致,能够在满足不同能源系统的运行约束,实现ICES经济最优运行的同时,保障ICES中多元能源主体的信息安全与涉密隐私。In order to guarantee the information safety and confidential privacy of diverse energy entities among the integrated community energy system(ICES),and satisfy the multiple energy demand for electricity and heat,a decentralized optimal scheduling method is proposed in this paper.Firstly,the mathematical models of electric distribution system,natural gas distribution system and coupling system are established respectively and linearized by certain mathematical method.Secondly,the optimal scheduling model of ICES is developed with the operation cost set as the objective function.By introducing the consensus variable into the scheduling model,the optimal operation can be decoupled on the basis of the decentralized scheduling framework,which is suitable for the multiple entities integration for ICES.Finally,a typical ICES case is utilized to verify the proposed method.It is illustrated that the proposed decentralized scheduling method is able to provide the scheduling scheme same as that by centralized method,which is capable of the satisfaction for operation constraints,the realization of optimal operation and the protection of information safety and confidential privacy.
