OPTIMIZED PROVISION AND CONSUMPTION OF ELECTRICITY BY HOUSEHOLDS TO REDUCE NON-RENEWABLE ELECTRICAL ENERGY IN ELECTRIC GRID

A method comprising: receiving, by an apparatus or system, a first set of values for an electric grid, a second set of values for a first electricity supply, and a third set of values for a second electricity supply; receiving, by the apparatus or system, data from a plurality of electricity controllers, wherein all the received data form a fourth set of values, wherein each electricity controller of the plurality of controllers is associated with a household of a plurality of households and controls electricity supplied to the electric grid, stored and requested from the electric grid at the different time periods within the PT, wherein each household of the plurality of households comprises at least one renewable electrical energy production device and the fourth set of values is indicative of electrical energy producible by each device of the at least one renewable energy production device at the different time periods within the PT; solving, by the apparatus or system based on the first, second, third and fourth sets of values, an optimization problem.
