摘要
储能系统(ESS)具有削峰填谷,降低用户用电成本的作用.针对单用户独立投入储能系统成本过大的问题,提出了一种共享模式下的储能系统调度策略.考虑了一次性投资成本、运行维护、寿命周期、削峰获利等因素,以最小化日均投资运行成本为目标函数,加入了储能系统能量约束、功率约束、日均投资维护成本模型等,建立了混合整数线性规划(MILP)模型.研究了不同放电深度对日均投资成本的影响.仿真结果表明共享储能模式相对于单用户储能模式节省14.17%.
The energy storage system(ESS)has the function of shaving peak demand,filling demand valleys and reducing the cost of electricity consumption.To address the problem of excessive cost for a single-user independent ESS,we propose a scheduling strategy for the ESS in a shared model.We consider the factors such as one-time investment cost,operation maintenance,life cycle,and peak-shaving profit income.The objective function is to minimize the daily average investment operation cost.We establish a mixed-integer linear programming model and add some constraints,such as energy constraint,power constraint,and daily investment maintenance cost model of ESS.We also demonstrate the influence of different discharge depth on daily investment cost.Finally,we show that the shared ESS can save 14.17%on costs compared with the singleuser independent ESS.
