Abstract
A control device for controlling an energy consumption of a load on an electricity grid includes a sensor for sensing over a period of time values of a physical variable of the grid, where the physical variable varies in dependence on a relationship between electricity generation and load on the grid. The control device also includes apparatus for varying the energy consumption of said load.
Claims8
A control device for controlling an energy consumption of a load on an electricity grid, said control device comprising:
- means for sensing over a period of time values of a physical variable of the grid, said physical variable varying in dependence on a relationship between electricity generation and load on the grid;
- means for determining a floating central value of the physical variable of the grid using a plurality of former values of the physical variable of the grid;
- and
- means for varying the energy consumption of said load, said varying being dependent upon a recent value of the physical variable of the grid relative to said floating central value.
