The present invention relates to a power supply control device and more specifically, the power supply control device which switches a power supply source so that power is supplied from a power supply source when the power supply source has an amount of power greater than the power demand of a reservoir. Also the power supply control device changes the power supply source based on the current state of multiple power supply sources, which changes in real time, to allow reliable and yet flexible power supply in real time and therefore overcomes the limitation of conventional technology that is inefficient in allocation of resources in a sense that the consumer load is controlled when the utility system of a contractor cannot handle the peak load but another utility has enough power to spare and solves the problem with the traditional peak load controller by allocating resources in an inefficient manner when power supply utilities change by the minute. |
