The invention belongs to the technical field of methods for participating in power grid peak regulation flexibility transformation through a subcritical circulating fluidized bed, and particularly relates to a method for adapting to power grid deep peak regulation through a subcritical circulating fluidized bed boiler. The method can adapt to the power grid peak regulation requirement, in the newenergy power generation peak period, the boiler is subjected to banking, the steam turbine load is reduced to 3-8MW, auxiliary power and auxiliary steam are connected through another unit, that the unit does not release the power grid and operates for 2-3 hours at a low load, the requirement of the power grid valley peak regulation time period is just met, and meanwhile deep peak regulation compensation can be obtained to meet the profit requirement of a power plant. The method is easy to operate, power utilization systems of a unit system can be connected in series, benefit maximization of the unit in the banking per
