可燃冰是21世纪公认的新型清洁能源.由于可燃冰开采成本较高,其在各行业的购买单价可能会较高.所以,可燃冰的经济性研究是有必要的.针对某炼油厂工程项目,分别以煤、燃料油、天然气和可燃冰为燃料,以全周期总花费最少为目标,研究了蒸汽动力系统的多周期最优化调度问题.运用改进差分进化算法对其进行优化求解,数值结果表明:如果可燃冰的单价处于(0,3 900]$/t,可用可燃冰代替煤、燃料油和天然气作为燃料;如果可燃冰的单价处于(3 900,4 550] $/t,可用可燃冰代替煤、燃料油作为燃料;如果可燃冰的单价处于(4 550,5 400]$/t,可用可燃冰代替燃料油作为燃料;如果可燃冰的单价高于5 400 $/t,用其作为燃料不符合经济性原则,不能代替传统能源作为燃料. |

Combustible ice is known as the crown of 21st century new clean energy. Since the cost of exploiting combustible ice is high, the unit price of combustible ice may be rather high in all walks of life. So the economic analysis of combustible ice is meaningful. Aiming at a refinery engineering project, the multi-period optimal scheduling of steam power systems is studied with minimizing the total cost of all periods. Coal, fuel oil, natural gas and combustible ice are respectively used as fuel to solve the proposed model by an improved differential evolution algorithm. Numerical results show if the unit price of combustible ice lies in (0, 3 900]$/t, combustible ice can replace coal, fuel oil and natural gas as fuel; if the unit price of combustible ice lies in (3 900, 4 550]$/t, combustible ice can replace coal and fuel oil as fuel; if the unit price of combustible ice lies in (4 550, 5 400]$/t, combustible ice can replace fuel oil as fuel; if the unit price of combustible ice is higher than 5 400 $/t, then combustible ice can not replace coal, fuel oil and natural gas as fuel. |
