Abstract

This paper proposes a low-carbon operation scheduling method for the integrated energy system considering source-load uncertainty and flexible loads to fully utilize system energy flexibility of the system and mitigate the impact of source-load uncertainty on the scheduling plan. Firstly, to address the limitation of fuzzy C-means algorithm in dealing with high-dimensional data, a kernel-based similarity function is introduced to replace the original Euclidean distance, and the source-load characteristic indices are is selected for data dimensionality reduction. Secondly, the median absolute deviation is used to filter the discrete values in each category, and the model is constructed with the minimum sum of Euclidean distances as the objective function. The central values at each time step are solved by the sparrow search algorithm to generate typical scenarios. Finally, the scheduling is carried out to minimize the sum of operating cost, flexible load compensation cost, and carbon transaction cost in an uncertain environment considering the flexible electric load, flexible heat load, and the shiftable, transferable, and reducible characteristics of the flexible load. Simulation results show that the proposed scheme can effectively improve economic benefits.
