摘要: 考虑储能应用价值的容量相关性约束,提出了一种储能规模化应用商业模式精确定量评估方法。采用双梯级函数来表征电网对储能、火电等灵活性调节资源性能和容量的要求;根据储能在源、网、荷侧产生的发电量、输配电量、电费和辅助服务收益等增益,建立“储能+”场景下新能源业主、电网运营商、用户、储能业主等相关方的收入函数;根据增益耗费的储能容量,建立相关方分摊的储能成本函数;综合考虑新能源、电网、用户或者第三方等投资主体的净收益最大,建立储能投资博弈模型。最后,根据甘肃省的实际情况,评价了不同模式场景下规模化推广储能的商业模式,并对关键参数进行了灵敏度分析,论证了不同组合运营方式在特定源荷区域的效果,验证了所提方法的可行性。

Abstract: Considering the capacity-related constraints of the application value of energy storage, an accurate quantitative evaluation method for the business mode of large-scale energy storage applications is proposed. A double-cascade function is used to characterize the grid’s requirements for flexible adjustment of resource performance and capacity for energy storage, thermal power, etc. Then according to its revenue in power generation, transmission and distribution, electricity charge, and ancillary service income generated by energy storage at the source, grid, and load side respectively, an income function is established for stakeholders including new energy asset owners, grid operators, users, and energy storage asset owners in the “energy storage +” scenario. Based on stakeholders' share, an energy storage cost function is set up according to the energy storage capacity allocated for the corresponding revenue. Taking account of the investment entities such as new energy, power grids, users or third parties, a game model for energy storage investment is constructed with the objective as the maximization of the net income. Finally, according to the actual situation in Gansu Province, the business mode of large-scale promotion of energy storage under different mode scenarios was evaluated, and the sensitivity analysis of key parameters was conducted to demonstrate the effects of various combinations of operation modes on specific source-load regions. Therefore the feasibility of the proposed method is verified.
