Generation load control

A method for controlling a plurality of non-essential electrical loads to substantially avoid export of energy from at least one electrical energy generator to an electrical power grid, said plurality of non-essential electrical loads supplied by the at least one renewable energy generator connected to a premises and the electrical power grid, wherein the at least one renewable energy generator derives energy from a renewable energy source;

• said method comprising the steps of:
• a) sensing, by a bi-directional voltage and/or current sensing device, the AC voltage and/or current between the electrical power grid and the premises and providing a sensor input to a controller, the sensor input indicating the direction of power flow between the electrical power grid and the premises;
• b) determining the non-essential electrical loads to be connected by the controller on the basis of the sensed direction of power flow between the electrical power grid and the premises;
• c) connecting one or more non-essential electrical loads based on an output of the controller, wherein the controller is configured to reduce export of renewable energy to the power grid, whilst maintaining connection between the renewable energy generator, the premises, and the electrical power grid until power flow in the direction from the premises to the electrical power grid is not sensed by the bi-directional voltage and/or current sensing device.

Computer instruction code executable on a computer processor for controlling at least one of a plurality of non-essential electrical loads to substantially avoid export of energy from a renewable energy generator to an electrical power grid, said plurality of non-essential electrical loads being supplied by the renewable energy generator connected to a premises and/or an electrical power grid, wherein the renewable energy generator derives energy from a renewable energy source;

• the computer instruction code causing:
• sensing, by a bi-directional voltage and/or current sensing device, the AC voltage and/or current between the electrical power grid and the premises and providing sensor input to a controller, the sensor input indicating the direction of power flow between the electrical power grid and the premises;
• determination of the non-essential electrical loads that can be connected by the controller according to the sensed direction of power flow between the electrical power grid and the premises;
• and
• connection of one or more non-essential electrical loads based upon an output of the controller, until power flow in the direction from the premises to the electrical power grid is not sensed by the bi-directional voltage and/or current sensing device, wherein the controller is configured to reduce export of renewable energy to the power grid whilst maintaining connection between the renewable energy generator, the premises, and the electrical power grid.
