However, the separate management of these subsystems poses a considerable challenge for designing a fast and reliable M-EFC method. In this paper, a fixed-point based distributed method is proposed for the M-EFC problem. The proposed method can preserve the autonomy of subsystems due to limited information exchange during the solution process. Moreo-ver, the fast and reliable convergence is achieved according to the proposed sufficient conditions based on the fixed-point theory. Besides, the proposed method is availa-ble for multi-energy systems (MES) with various coupling relationships and different structures of information ex-change. Simulations on a MES demonstrate that the pro-posed method has remarkable superiority compared to the unified Newton-Raphson method in computation time, accuracy and robustness against data loss.enAttribution-NonCommercial 4.0 InternationalDistributed methodenergy flow calculationfixed-pointhigh-order nonlinear equationmulti-energy systemArticle
