all of the functions for providing a responsive load service the non processor circuits may include but are not limited to a communications transceiver such as a radio receiver and a radio transmitter signal drivers clock circuits power source circuits and user input devices alternatively some or all of the responsive load service functions could be implemented by a state machine that has no stored program instructions or in one or more application specific integrated circuits asics in which each function or some combinations of certain of the functions are implemented as custom logic of course a combination of these approaches could also be used thus methods and means for these functions have been described herein further it is expected that one of ordinary skill when guided by the concepts and principles described herein will be readily capable of generating such software instructions and programs and ics with minimal experimentation in fig1 a power supply grid 10 comprises one or more power generators 20 coupled via a first power distribution network 40 to one or more power consuming devices adapted to operate as responsive loads 30 in a responsive load service the power grid 10 is also coupled either via the same first power distribution network 40 or via a separate second.
