doi:10.11930/j.issn.1004-9649.201903117

Abstract

Abstract: Given the background of energy internet development, the district integrated energy system has become an efficient and clean terminal energy consumption carrier. Based on the electricity-gas-heat multi-energy coupling system framework, this paper analyzes the operating economy of district integrated energy system with consideration of the threat of potential natural disasters. Aimed at the contradiction between the resilience of district integrated energy system to disasters and its operating economy, a multi-objective optimization scheduling method is proposed. Then, the increase of operating costs caused by the improvement of resilience to potential natural disasters and the overall economic performance of system are coordinated by the multi-objective weighted fuzzy programming method. Finally, the feasibility of the proposed multi-objective optimization scheduling method is verified by a case study. The result shows that the resilience of district integrated energy system to natural disasters can be enhanced effectively at the expense of certain operating economy.

Key words: district integrated energy system, resilience, multi-objective weighted fuzzy programming, optimal dispatch
