Method and regulating device for regulating an electrical power transfer

A regulating device for regulating an electrical power transfer from two power supply units to a power consumption unit, the regulating device comprising:

• a processor and a memory storing a set of instructions, the instructions, when loaded and executed by the processor, causing the processor to:
• provide a first data set with information regarding a minimum and maximum electrical power supply rate for each of the two power supply units;
• provide a second data set with information regarding a power requirement of the power consumption unit, and a non-zero maximum period of time for which the power requirement may be temporally shifted for convenience of the two power supply units, and a weighting of each of the power supply units, wherein the weighting depends on a respective form of power generation and/or location;
• provide a target function for an optimization method, wherein the target function includes the first data set, the second data set, and the weightings of the power supply units as parameters;
• wherein the target function calculates a price for the power supplied by each of the two power supply units and/or a carbon dioxide emission rate for each of the two power supply units;
• analyze the target function to identify a local maximum or a local minimum as an extreme value complying with the maximum period of time;
• and
• regulate the power transfer from each of the two power supply units to the power consumption unit to achieve the extreme value of the target function.
