Abstract

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
