摘要/Abstract

摘要：

北方地区合理利用大规模弃风电量，特别是将弃风用于清洁供暖，必将产生巨大的社会效益。本文重点研究弃风电量与储热容量匹配关系，以及评估某省级电网连续5年储热跟随弃风运行情况。首先，提出基于年弃风电量、年最大弃风功率和最大日弃风电量的全额消纳弃风储热容量配置方法，以及基于年最大弃风功率按百分比部分消纳弃风的储热容量配置方法。然后，根据分布式储热和集中式储热的运行特性，构建储热跟随弃风能力的评估模型。最后，通过某省级电网连续5年的实际运行案例进行数值分析，研究供暖季和供暖季低谷期弃风消纳问题。弃风消纳电量与储热配置容量结果显示，储热装置对电网弃风消纳效果显著，随着风力发电装机容量增加，储热配置容量也应增加才能满足弃风消纳需求，且不以百分百消纳弃风电量为目标配置储热容量更经济。此外，储热跟随弃风评估结果显示，基于年弃风电量配置储热功率更符合电网的实际运行情况，储热应跟随弃风规律运行才能提升电网消纳弃风的能力。

Abstract:

The rational use of large-scale abandoned wind power in the northern region, especially for clean heating, has significant social benefits. This study investigates the matching relationship between abandoned wind power and heat storage capacity. To do this, the heat storage operation following the abandoned wind power of a provincial power grid for the past 5 years is evaluated. First, a configuration method for the heat storage capacity consuming the entire abandoned wind is proposed based on the annual abandoned wind power, maximum abandoned wind power, and maximum daily abandoned wind power. The allocation method for the heat storage capacity consuming the abandoned wind by a percentage based on the maximum abandoned wind power is also provided. Second, an evaluation model of the heat storage following the abandoned wind is built according to the operation characteristics of the distributed and centralized heat storages. Finally, the actual 5-year operation of a provincial grid is analyzed. The problems of consuming abandoned wind power in the whole heating season and the low load period of the heating season are investigated. Some conclusions are drawn from the results of the abandoned wind consumption and the heat storage configuration capacity. The results show that heat storage devices significantly affect the abandoned wind consumption of the power grid. Considering the increasing installed capacity of wind power, the heat storage configuration capacity should be raised to meet the demand for abandoned wind power. Furthermore, configuring the heat storage capacity without consuming the entire abandoned wind is more economical. The evaluation results of the heat storage following the abandoned wind power are presented herein. The heat storage capacity configuration based on the annual abandoned wind power is in accordance with the actual power grid operation. In conclusion, heat storage devices should operate following the law of abandoned wind to increase the abandoned wind consumption.

Key words: abandoned wind power, distributed heat storage, centralized heat storage, capacity configuration, abandoned wind power consumption assessment
