Method for controlling heat supply substations in regional heat supply network

The invention relates to a method for controlling a heating substation in a regional heating network, comprising: establishing a building thermal performance numerical model, each numerical model corresponding to each user space in a secondary network, each numerical model comprising parameters adapted to obtain a virtual indoor temperature at the user space; the method comprises the following steps: calibrating parameters by using recorded indoor temperature of a user space obtained in a calibration period, a secondary network recorded heat supply parameter and weather data as boundary conditions, and obtaining a calibrated building performance numerical model; selecting a representative numerical model under a predetermined condition; calculating a target heat supply parameter according to the virtual indoor temperature obtained by the selected representative numerical model, the local weather data and the target temperature of the heat supply substation; and providing the target heat supply parameters to c
