A method for controlling suction pressure in a vapour compression system including one or more cooling entities is disclosed. For each cooling entity, a maximum required suction pressure and/or a required change in suction pressure for maintaining a target temperature in the refrigerated volume is obtained. A most loaded cooling entity among the one or more cooling entities is identified, based on the maximum required suction pressures and/or the required changes in suction pressure. The suction pressure of the vapour compression system is controlled in accordance with the maximum required suction pressure and/or required change in suction pressure for the identified most loaded cooling entity.

Method for controlling suction pressure based on a most loaded cooling entity

The invention relates to a method of operating at least one distributed energy resource comprising a refrigeration system () with a number of cooling entities, wherein

Method for operating at least one distributed energy resource comprising a refrigeration system

A method for controlling operation of a refrigeration system (), including one or more refrigeration entities (), is disclosed. Each entity controller () obtains a measure for an error value between the measured value of a compressor control parameter and a setpoint value () for the compressor control parameter, and each entity controller () adjusts a refrigeration load of the corresponding refrigeration entity () to correspond to a cooling capacity of the compressor(s) (), and in accordance with the obtained measure for an error value.
