The method comprises the following steps of establishing a thermal storage tank capacity optimization configuration model which includes a thermal storage tank capacity optimization configuration target function and a corresponding constraint condition; and using a branch and bound method to solve the thermal storage tank capacity optimization configuration model and completing thermal storage tank capacity optimization configuration. By using the thermal storage tank capacity optimization configuration method used for increasing the wind power absorption ability and the system thereof, randomness and fluctuation performance of wind power output, a thermal load demand of a user and thermal storage and release characteristics of a thermal storage tank are integratedly considered so as to realize flexible output adjusting of a heat supply unit and increase a wind power utilization rate.

Description

technical field [0001] The present invention relates to a configuration method, in particular to a heat storage tank capacity optimization configuration method and system for improving wind power absorptive capacity. Background technique [0002] During the heating period in winter in northern China, cogeneration units operate in the mode of constant heat and electricity, and the output of cogeneration units needs to be maintained at a relatively high level for heating. When the output level is higher, the space for the power system to accept wind power is reduced, and the phenomenon of wind abandonment is serious. Thermal power plants can relax the heat-electricity constraint relationship of cogeneration units by configuring heat storage tanks with a certain capacity. When the power system has room for wind power, the heat storage tanks can be used for heat storage. The tank releases heat to reduce the thermal load output of the thermal power unit, thereby reducing the ele...
