摘要: |
近年随着储能应用技术的进步,中国电力市场中电化学储能装机规模爆发式增长,准确量化储能项目商业价值,将有利于储能产品或服务参与电力市场竞争,促进储能行业可持续发展。以范围经济理论、成本收益理论为基础,建立了全要素可放电电价随机模型,来刻画和评价多功能储能项目商业价值。与此同时,分析了影响可放电电价的参数属性和发电侧、电网侧、用户侧储能项目获得经济收益和参与市场竞争的约束条件,提出了储能企业竞争策略和投资决策思路。结合算例和学习曲线,分析发现装机成本、系统利用效率、能源转化效率三个参数对可放电价格影响尤为显著,企业可以根据不同参数对可放电价格水平的影响程度,来确定适合企业的商业模式,并优化经营策略。综合商业价值量化模型为企业投资、市场竞争、政策制定,提供了清晰思路和决策工具。 |

Abstract: |
With the development of energy storage application technology in recent years, the installed scale of energy storage has experienced an explosive growth in China's power market. The accurate quantification of commercial value of energy storage projects will help energy storage products or services to participate in the power market competition and promote the sustainable development of energy storage industry. Based on the theory of scope economy and cost benefit, a stochastic model of total factor discharging electricity price is established to describe and evaluate the commercial value of multifunctional energy storage project. Not only that, the paper analyzes the parameter attributes that affect the discharging electricity price and the constraint conditions that the power generation side, power grid side and user side energy storage projects obtain economic benefits and participate in the market competition. From this, it suggests the competition strategy and investment decision of energy storage enterprises. Based on the calculation example and learning curve, it is found that the three parameters of installation cost, system utilization efficiency and energy conversion efficiency have significant influence on the discharging price. So that enterprises can determine the appropriate business model and optimize the operation strategy according to the influence degree of different parameters on the discharging price level. Therefore, the comprehensive business value quantitative model provides clear thinking and decision-making tools for enterprise investment, market competition and policy formulation.
