A collaborative optimization strategy of an integrated energy system aiming at improving energy efficiency is studied in this paper for the cluster optimization of an integrated energy system (IES). In this paper, an improved discrete consistency method based on the coordination optimization method for IES is proposed. An IES model considering the mixed energy supply of electricity, heat, and gas is constructed in a single region. And then an objective function with the maximum return is established, on the premise of assuming that the prices of electricity, heat, and gas can be used as an economical means to adjust the energy utilization. Finally, the consistency theory is applied to the IES, and the improved discrete consistency algorithm is utilized to optimize the objective function. In the case study, a certain region IES is taken as an example in Northeast China. The case study demonstrates the effectiveness and accuracy of the coordination optimization method for IES.

基于一致性理论的多区域互联综合能源系统优化策略

本文针对集成能源系统（IES）的集群优化，研究了旨在提高能源效率的集成能源系统的协作优化策略。提出了一种基于协调优化方法的IES改进离散离散方法。在单个区域中构建了一个考虑到电，热和气混合能源供应的IES模型。然后，在假定电，热和天然气价格可以用作调节能源利用的经济手段的前提下，建立具有最大回报的目标函数。最后，将一致性理论应用于IES，并利用改进的离散一致性算法优化目标函数。在案例研究中 以东北某区域IES为例。案例研究证明了IES协调优化方法的有效性和准确性。
