Claim 0:
1. A method for controlling a local distribution system's outtake of heat from a thermal energy distribution grid, wherein the local distribution system comprises:
a device for exchange of thermal energy between the local distribution system and the thermal energy distribution grid,
one or more thermal energy distribution devices,
a feed for feeding the one or more thermal energy distribution devices with thermal energy from the device for exchange of thermal energy by conducting a heat transfer fluid, and
a return for returning the heat transfer fluid from the one or more thermal energy distribution devices to the device for exchange of thermal energy, the method comprising:
determining a base steering temperature for the local distribution system's outtake of heat from the thermal energy distribution grid;
receiving, at the local distribution system, a control signal indicative of reducing a steering temperature for the local distribution system's outtake of heat from the thermal energy distribution grid;
determining a reduced steering temperature for the local distribution system's outtake of heat from the thermal energy distribution grid based on the control signal and the base steering temperature;
determining a return temperature of the heat transfer fluid in the return,
upon the determined reduced steering temperature being lower than the return temperature, determining a temporary steering temperature being higher than the return temperature and lower than the base steering temperature; and
controlling the local distribution system's outtake of heat from the thermal energy distribution grid based on the temporary steering temperature.
