Optimal Configuration Method of County-Level Integrated Energy Distribution System for Carbon Power Synergy

To deal with the problem of supply and demand balance throughout the functioning of County-level Integrated Energy Distribution System, this paper proposes a two-layer optimization strategy for the comprehensive energy system that considers the ambiguity of wind power and integrated demand response. The goal of the upper layer model is maximizing the annual operating revenue of the multi-energy coupled distribution system, and establishes an electricity-hydrogen-carbon synergistic scheduling model; the lower-layer model calculates the minimum yearly load aggregator’s usage cost as the optimization goal, and takes into account the consumers’ integrated demand response. Secondly, to characterize the uncertainty, resilient optimization theory is presented and two-layer model is solved using KKT condition and Big-M method. Finally, a relevant case study is conducted based on a county multi-energy coupled distribution system in a region to demonstrate the feasibility and effectiveness of the proposed method.
