1. A system for controlling voltage supply to a portion of a distribution grid, the portion of the grid including a substation comprising:
one or more circuit elements operable to increase or decrease the voltage supplied to consumers within the portion of the grid,
the system for controlling voltage supply providing a data set including a previously measured power consumption associated with previously measured values of at least one property for a portion of the grid, the at least one property being one of voltage, current, frequency or load, or a combination thereof,
the voltage control system providing a measurement device to measure the at least one property supplied within the portion of the grid, and
the voltage control system providing a processing device determining an effect of altering the voltage supplied to the consumers within the portion of the grid from a first value to a second value, wherein the determining uses previously measured values of the at least one property in the data set and includes the consumers, within the portion of the grid, changing their power consumption based upon the altering of the voltage from the first value to the second value,
wherein the substation includes a capacitor connectable to the portion of the grid to alter the voltage supplied to the consumers within the portion of the grid, and wherein the value of the at least one property and the power consumption are measured and added to the data set in response to capacitor connection or disconnection from the portion of the grid.
