摘要
由于电热综合能源系统各主体信息不共享、存在隐私保护等,区域内不同主体的自治决策和通信安全变得至关重要。为此,提出一种基于交替方向乘子法(ADMM)的电热综合能源分布式优化方法,以实现电热综合能源系统中能源集线器(EH)的自治决策和分布式优化。建立了电热综合能源系统与EH的优化调度模型,并建立了基于ADMM的电热综合能源系统分布式优化模型,实现了综合能源系统运营商与多个EH运营商的分布式功率交互。同时,采用自适应步长的方法求解所建立的模型,提高了算法的收敛性。
Due to the lack of information sharing,privacy protection and so on for subjects in the integrated electricity-heat energy system,the autonomous decision-making and communication security of different sub⁃jects in the region become crucial.Therefore,a distributed optimization method of integrated electricity-heat energy system based on ADMM(Alternating Direction Method of Multipliers)is proposed to realize the autono⁃mous decision-making and distributed optimization of EH(Energy Hub)in the integrated electricity-heat energy system.The optimal dispatching model of the integrated electricity-heat energy system and EH is established,and then,the distributed optimization model of the integrated electricity-heat energy system based on ADMM is established,which realizes the distributed power interaction between the integrated energy system operator and multiple EH operators.At the same time,the adaptive step size method is used to solve the constructed model,so that improving the convergence of algorithm.
