| 中文摘要: |
| 新能源的高比例渗透对我国风力与光伏发电的经济与效益产生影响，导致电网灵活性下降、调峰能力不足、就地消纳困难、弃风弃光等现象的发生。针对当前电力系统所处的困境，有必要适度发展蓄热技术，研究基于风电和光电就地消纳的熔盐蓄热技术，提高电力系统调峰调频能力，有效发挥移峰填谷的优势。以江苏省的学校、医院锅炉使用情况为依据，进行电能替代潜力分析，通过建立生命周期成本模型（LCC）对不同类型的锅炉进行经济性对比分析，包括初投资成本、运行成本、维护成本，从而为设备选择、投资优化提供依据。 |
| 英文摘要: |
| The high proportion of new energy penetration has affected the economy and benefits of wind power and photovoltaic power generation in China, resulting in the decline of power grid flexibility, insufficient peaking capacity, difficulty in local consumption, and the abandonment of wind and light. In view of the predicament of the current power system, it is necessary to vigorously develop heat storage technology, study thermal storage technology of molten salt based on local consumption of wind power and photoelectric power, improve the capacity of peak and frequency regulation of power system, and effectively exert the advantages of shifting peaks and valleys. Based on the use data of schools and hospital boilers in Jiangsu Province, the potential of electric energy substitution is analyzed. And life cycle cost model（LCC）is established to conduct economic comparative analysis of various types of boilers, including initial investment cost, operating cost, maintenance cost, so as to provide a strong basis for equipment selection and investment optimization. |
