摘要
地热作为清洁低碳、安全高效的绿色能源,具有极好的应用前景。以雄安新区12万平方米的组团式建筑群为假设场景,提出了多能互补式、储能式两种地热能利用系统方案。通过编写数学计算模型、优化算法等处理方法分析了初投资、运行成本、能源节约、费用年值等评价指标的能源系统综合效益,最终确定合理的储能式能源系统方案,与多能互补式方案相比,储能式方案初投资减少14.6%、运行成本降低7.1%、费用年值降低9.9%。
As a clean and low carbon, safe and efficient green energy, geothermal has excellent application prospect. Two integrated energy systems using geothermal energy are developed for the theoretical office buildings and residential construction in Xiongan New Area to reduce the energy consumption and improve the energy utilization. Cost-benefit are analyzed for each type of energy system. Economic indicators are used to evaluate the systems economics in terms of the initial investment, operating cost, energy conservation rate and annual total cost. The results indicate that the integrated energy systems using geothermal energy with storage have better energy conservation and economics. The initial investment of energy storage system is reduced by 14.6 %, the operating cost is lowered by 7.1 % and annual total cost is reduced by 9.9 %.
