摘要
地面储能技术已成为提升城轨交通节能和供电质量的有效措施,技术经济性评价是储能技术工程应用须解决的重要问题。该文在回顾城轨交通制动能量回收超级电容阵列功率-容量约束配置法与容量约束配置法的基础上,提出地面超级电容储能系统的综合技术经济性评价指标并建立净收益数学模型,案例对比分析了上述两种典型配置方法的技术经济性。案例研究表明:功率-容量约束配置法投资成本虽高于容量约束配置法投资,但两种配置方法成本回收年限相近;功率-容量约束配置法节能性能优于容量约束配置法,全寿命周期内功率-容量约束配置法综合技术经济性更好,可获得更大的经济收益,实际工程中值得优先采用。
Stationary energy storage technology has become an effective measure to improve energy saving and power supply quality of urban rail transit.Technical and economic evaluation is an important issue to be solved in the engineering application of energy storage technology.Based on the review of the power-capacity constrained configuration method(P&C-Method)and capacity constrained configuration method(C-Method)of supercapacitor array for urban rail transit braking energy recovery,the comprehensive technical and economic evaluation criteria and a net income mathematical model of the stationary supercapacitor energy storage system was established.The technical economy of the above two typical configuration methods is compared and analyzed.The case study shows that:Although the investment cost of P&C-Method is higher than that of C-Method,the cost recovery period of two configuration methods is similar,the energy-saving performance of the power-capacity constraint configuration method is better than that of the capacity constraint configuration method,within the whole life cycle.The power-capacity constraint configuration method has better comprehensive technical and economic performance and can obtain greater economic benefits.It is worthy of priority in practical engineering.
