Abstract

Aiming at the problem of multi-subject benefit distribution in the integrated energy microgrid permeated by hydrogen-enriched compressed natural gas （HCNG）, this paper proposes a low-carbon economic dispatch method based on a bi-level game. Firstly, the electrolysis hydrogen production equipment and hydrogen mixing combustion engine are modeled in a refined way, and the HCNG load is introduced on the load side to improve the whole process of hydrogen from production to utilization. Secondly, carbon trading and demand response mechanisms are introduced to fully explore the carbon reduction potential on the load side while limiting carbon emissions on the source side. The game relationship between microgrid operator （MGO） and load aggregator （LA） is analyzed, and a Stackelberg game model of the upper MGO and the lower LA is established. Then, the model of the paper is solved by using the black-winged kite optimization algorithm combined with CPLEX. Finally, the effectiveness of the proposed method is proved through the comparison of arithmetic examples. The proposed method can effectively equalize the benefit distribution between MGO and LA while reducing the carbon emission of microgrid and improving the rate of renewable energy consumption.
