Abstract: A control system is disclosed which varies the operation of consumer's devices to minimize influx currents across a power grid. Power consuming devices are scheduled to operate in accordance with varying pricing tiers. As customers schedule the operation of various devices and appliances in accordance with pricing tiers, when the tiers change, the current drain on the power grid increases significantly. Even increasing the strain on the power grid is the fact that the start-up current for electric motors is up to six times their normal operating current. When started, as electric motors place a heavy strain on a power grid, the power strain lead to the disruption of power to the very consumers requiring more power. The present invention randomizes the start up times of the controlled devices so as to minimize the strain of the power grid as each one comes on line.

Abstract translation: 公开了一种控制系统，其改变消费者设备的操作，以最小化跨越电网的流入电流。 耗电设备按照不同的定价层次进行运行。 随着客户根据定价层次对各种设备和设备的运行情况进行调度，当层次发生变化时，电网上的电力消耗明显增加。 即使增加电网的应变，电动机起动电流高达正常工作电流的六倍。 当电动机起动时，由于电动机在电网上施加了巨大的压力，所以电力应变导致对需要更多功率的消费者的电力中断。 本发明随机化受控设备的启动时间，以使每个线路上的电网的应变最小化。
