Description

technical field [0001] The invention belongs to the technical field of frequency modulation of heat and power cogeneration units, and in particular relates to a method for excavating frequency modulation capability from building thermal inertia in a steam extraction control mode. Background technique [0002] In the context of large-scale new energy development and application, areas with a high proportion of cogeneration units occupy a large number of conventional frequency modulation units during the warm winter period, resulting in a sharp decline in frequency modulation capacity in areas where frequency modulation resources are scarce. However, construction of new frequency modulation units in the above areas Most of the resources do not have engineering feasibility, so the excavation of the frequency regulation capability of cogeneration units has become an important measure to solve the above problems.
