Given the huge pressure on peak regulation of Liaoning power grid in the heating season

the methods of reducing the heating unit electric load as far as possible on the premise of guaranteeing the quality of heating

and rationally arranging the electricity plan

can achieve maximum wind power accommodation. Based on the on-line monitoring system of ordering power by heat of heating units

an energy balance method is put forward. Through the balance calculation of the energy entering or exhausted from the steam turbine

and the determination of the unit power generation relationship with different heating and industrial extraction steam quantities of heat

the maximum and minimum power generation can be accurately calculated with a given heating and industrial extraction steam quantity of heat. The accuracy and practicality of the model of ordering power by heat is verified through practical application.
