Abstract: The present invention relates to a method for controlling one or more heat pumps (110) connected to a distribution grid (10) for fluid-based distribution of heating and cooling in order to, at least partly, compensate for a cold outtake from the distribution grid (10) by a first cooling machine (120) connected to the distribution grid (10). Alternatively, or in combination, one or more cooling machines (120) connected to the distribution grid (10) may be controlled in order to, at least partly, compensate for a heat outtake from the distribution grid (10) by a first heat pump (120) connected to the distribution grid (10). The controlling is made a control server (200) monitoring outtake of heat and/or cold from the distribution grid (10) by the heat pumps (110) and cooling machines (120) connected to the distribution grid (10). The control server (120) generates and sends out control messages to the heat pumps and/or cooling machines.
