新能源侧储能系统综合经济效益评估方法与实例

Comprehensive Economic Benefit Assessment Method and Example of Energy Storage Based on Generation Side

随着储能技术的不断发展,储能在用户侧、发电侧及电网侧应用场景日益增多。但目前新能源侧储能尚未形成成熟的商业及盈利模式,有必要针对新能源侧储能综合经济效益进行评估。本文提出储能系统全寿命周期成本分析方法,全面考虑新能源侧储能在电源装机、节能减排等方面的综合效益,构建综合经济效益评价模型及方法,并通过典型实例对方法进行验证。结果表明,随着电池寿命增加、电池成本下降,储能系统具备较好的经济可行性。

With the continuous development of energy storage technology,more and more scenarios of energy storage are applied in user side,generation side and power grid side.However,there is no mature commercial and profit model for renewable energy-side energy storage system,so it is necessary to evaluate the comprehensive economic benefits of renewable energy-side energy storage system.In this paper,a full life cycle cost analysis method for energy storage system is proposed.Considering the comprehensive benefits of renewable energy-side energy storage system in power supply installation,energy saving and emission reduction,an input-output benefit evaluation model and method for grid-side energy storage system are constructed and verified by typical examples.The results show that with the increase of battery life and the decrease of battery cost,the economic benefits of energy storage become more and more obvious.
