Abstract

Under the goal of "double carbon", deep peak regulation of coal-fired units is one of the important means to absorb new energy generation and improve the stability of power grid. In this paper, EBSILON software is used to build the heat storage and peak regulation model of secondary reheat unit, with 30% THA as the base condition to discuss the influence of main steam and primary reheat cooling section steam on the peaking capacity, the feasibility of heat storage and peak regulation and the utilization rate of the system. The results show that the main steam is more efficient than the primary reheat cooling steam in the process of reducing the unit load, improving the unit thermal efficiency in the process of heat release.
