The present invention provides a load control system to control peak demand power, capable of adjusting power supplied to a plurality of load devices to prevent target power from being exceeded. The load control system comprises: an electronic watt-hour meter to measure power consumption of a customer; a direct load control device to supply power to a plurality of load devices installed in the customer, use a watt-hour pulse transferred from the electronic power meter, a demand time pulse, and preset target power (maximum demand power for 15 minutes) to calculate reference power, current power and estimated power, and to control the power supplied to the load devices to prevent power consumption of the load devices from exceeding the target power based on a calculation result; a monitoring unit to receive and display information calculated in the direct load control device, to set the target power, and to modify internal setting information of the direct load control device when exchanging data with the direct load control device; and a server to receive the information calculated in the direct load control device and to directly control the direct load control device to adjust the power supplied to the load devices when exchanging data with the direct load control device by being connected to the direct load control device through an internet network. |
