1. A method of controlling operation of a component connected to an electricity supply network, the component being either a generator or load of a type that is able to store energy within and is operable at a range of power levels between zero and a maximum power CD, the method comprising the steps of:
(a) operating the component over a time period such that, within the time period, adjustments are made to a rate at which energy is transferred between the component and the supply network in accordance with a baseline power function B(t); and
(b) simultaneously operating the component over the time period such that adjustments are, in addition, made to the rate at which energy is transferred between the component and the supply network in accordance with a fast-moving power function F(t), such that the fast-moving power function F(t) is superimposed on the baseline power function, wherein
the baseline power function B(t) is derived from a slow-moving power function D(t), the baseline power function B(t) is set such that it is equal to the slow-moving power function D(t), provided that D(t) is not within a range δCD, δ<<1 of either 0 or the maximum power CD; and, if D(t) is within this range, B(t) is set to either δCD or (1−δ)CD respectively, wherein
if adjustments are made to the rate at which energy is transferred between the component and the supply network in accordance with the slow-moving power function D(t), the component would benefit economically from a variation in a prevailing price of electricity on the network or a variation in a value that can be derived, directly or indirectly, from the supply of electricity on the network, and
adjustments made to the rate at which energy is transferred between the component and the supply network in accordance with the fast-moving power function F(t) are adjustments that are responsive to and such as to counter imbalances between power generation and power consumption over the electricity supply network, the adjustments being less than the maximum power CD.
