Method for controlling a load
First Claim
1. A method for controlling a load, comprising:
- providing a total energy consumption of the load and a time window for the total energy consumption of the load from one or more energy sources,determining energy blocks, wherein the energy blocks are based on a power interval during a time interval, and wherein the time intervals are within the time window, andwherein the energy blocks are allocated energy-source-dependent costs,sorting the energy blocks in ascending order according to a level of the cost per energy block, wherein the costs of the energy blocks are determined by taking into account the consequential environmental costs of the energy producers producing them,summating quantities of energy that the energy blocks contain in ascending order of sorting until the total energy consumption of the load is reached,determining on and off times of the load using the time intervals that belong to the summed energy blocks, wherein the power intervals belonging to the respective energy blocks determine a power consumption of the load at the respective instant, andactuating the load in accordance with the determined on and off times.

Abstract
A method for controlling a load by providing a total energy consumption and a time window for the total energy consumption of the load from one or more energy sources is described. The method includes determining of energy blocks, wherein the energy blocks are based on a power interval during a time interval, the time intervals are within the time window and the energy blocks are allocated energy-source-dependent costs, sorting of the energy blocks in ascending order according to the level of the costs per energy block and subsequent summation of quantities of energy that the energy blocks contain in ascending order of sorting until the total energy consumption of the load is reached. From this, on and off times of the load are determined by means of the time intervals that belong to the summed energy blocks, wherein the power intervals belonging to the respective energy blocks determine a power consumption of the load at the respective instant, and the load is actuated in accordance with the on and off times. An apparatus for carrying out the method is likewise disclosed.

6. A method for controlling a load, comprising:
-
providing a total energy consumption of the load and a time window for the total energy consumption of the load from one or more energy sources, determining energy blocks, wherein the energy blocks are based on a power interval during a time interval, and wherein the time intervals are within the time window, wherein a quantity of energy blocks that is obtained from at least one renewable energy source is determined by using a forecast, wherein when an upper supply limit is applied, the energy blocks that are obtained from the at least one renewable energy source and that exceed the upper supply limit in accordance with the forecast are assigned the lowest costs, and wherein the energy blocks are allocated energy-source-dependent costs, sorting the energy blocks in ascending order according to a level of the cost per energy block, summating quantities of energy that the energy blocks contain in ascending order of sorting until the total energy consumption of the load is reached, determining on and off times of the load using the time intervals that belong to the summed energy blocks, wherein the power intervals belonging to the respective energy blocks determine a power consumption of the load at the respective instant, and actuating the load in accordance with the determined on and off times.
