Optimization Scheduling of Mine Integrated Energy Systems with Combined Operation of Abandoned Mine Pumped Storage and Water Source Heat Pumps

Abstract

In order to further constrain the carbon emission of Mine Integrated Energy System (MIES) and reduce the operating cost of MIES, a mining area optimization scheduling model with both low carbon and economy was proposed. Our novel approach integrates Abandoned Mine Pumped Storage (AMPS) and Water Source Heat Pumps (WSHP) for the first time. AMPS supplies a stable heat source for WSHP, facilitating thermoelectric decomposition and wind power coupling. Additionally, AMPS serves as efficient energy storage for coal mines. In the operational phase, it collects and utilizes the methane emitted during the coal mining process, reducing the waste of derived resources. The study also conducts a comprehensive analysis of the impact of Carbon Capture Systems (CCS), Power-to-Gas (P2G), and Combined Heat and Power (CHP) units on MIES. By optimizing unit output via CPLEX solver, our model minimizes system operating costs and incorporates carbon trading mechanisms. Comparative analysis of scheduling scenarios validates our strategy's efficacy.
