<p>A smart responsive electrical load 10 is connected to an electricity supply network 20 (e.g. national grid/mains), where the smart responsive electrical load 10 comprises an electrical power consuming device 30 (e.g. a domestic kettle or the battery for an electric vehicle) and a control arrangement 40 for controlling the supply of electrical power from the network 20; the control arrangement 60,110,150,160,170 operates by imposing a variable time delay tpbefore supplying electricity to the device 30 after a request for power to be provided to the device 30 has been sent, the variable time delay tpis a function of a state of the network 20. Preferably a state of the network 20 that variable time delay tpis dependent upon could be the supply frequency f of said network 20.</p> |
