Method for balancing power loads in an electrical power grid

Method for balancing in an electrical grid, wherein the grid comprises a group of households that are connected to the grid, 1) the feeding of a surplus of electrical power to the grid by one or more households and 2) the consumption of electrical power from the grid by one or more households;

• the method comprising
• a) measuring the net electrical power transmission (Pnet) of each of the households over a time interval (t1), wherein the net electrical power transmission (Pnet) of each of the households is an average value over the time interval (t1), and wherein the net electrical power transmission (Pnet) of each of the households may be a net electrical power production, a net electrical power consumption or a zero net electrical power transmission;
• thereafter
• b) calculating the total electrical power production (Ptotal production) of those households that have a net electrical power production and calculating the total electrical power consumption (Ptotal consumption) of those households that have a net electrical power consumption;
• thereafter
• c) calculating the ratio of the total electrical power production and the total electrical power consumption (Ptotal production/Ptotal consumption);
• thereafter
• d) determining whether the ratio (Ptotal production/Ptotal consumption) obtained under c) is above a first predetermined value or below a second predetermined value;
• thereafter
• e) in case the ratio (Ptotal production/Ptotal consumption) is above the first predetermined value, generating a first signal which
• 1) causes an electrical appliance in one of the households to turn on;
• and/or
• 2) notifies that there is a net electrical power production in the group of households;
• thereafter
• f) in case the ratio (Ptotal production/Ptotal consumption) is below the second predetermined value, generating a second signal which
• 1) causes an electrical appliance one of the households to turn off;
• and/or
• 2) notifies that there is a net electrical power consumption in the group of households;
• thereafter
• g) repeating the sequence a)-f) at least once.
