A responsive load (140) includes at least one power-consuming device (210, 220, 230) connected via an electrical power network (130) to a power generation arrangement (120), and connected via a communication arrangement to a control arrangement (110). The responsive load (140) is operable to provide an autonomous load response depending upon a characteristic of an electrical supply, for example if the supply frequency falls under high demand. The responsive load (140) is operable to provide an autonomous load response whose characteristics are determined by which process is being executed by the responsive load (140), or by a control signal received at the responsive load (140). Alternatively, it may provide an output indicative of whether or not the responsive load (140) is operable to provide a load response, or provide an autonomous load response depending upon processes which have been previously executed by the responsive load (140). The responsive load may also be provided with an â inactiveâ mode in which no response is provided. The number of on/off cycles, or ramp cycles, which the load undergoes whilst providing response may be limited. The load may also select from a number of operating algorithms to provide response. |
