Embodiment approach

[0112] The power control method and power distribution management method according to the present invention can be programmed for computer execution, and these methods can be stored in a computer-readable recording medium. The computer-readable recording medium includes all types of recording devices in which data is stored in a computer-readable manner. Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and carrier waves (eg, data transmission via the Internet). Bit streams generated by the power control method and power distribution management method according to the present invention can be stored in a computer-readable recording medium, and can be transmitted via a wired / wireless communication network.

Abstract

The present invention provides a power control method and a power control apparatus. The power control method of the present invention comprises the steps of: a first charge comparison step for receiving charge information of supplied power, and comparing the charge of the supplied power with a preset reference charge; and a second charge comparison step for comparing the charge of the supplied power with the preset lowest charge. Further, the method comprises the steps of: a first power quantity comparison step for confirming a stored power quantity within a power storage unit, and comparing the stored power quantity with a preset reference power quantity; and a second power quantity comparison step for comparing the stored power quantity with a preset power quantity demand. Further, the method comprises a control step for selecting one of externally supplied power and internally stored power as the usage power for the customer, through at least one of a charge comparison step and the power quantity comparison step. Particularly, the invention is characterized in that: if the charge of the supplied power is lower than the reference charge or the charge of the supplied power is higher than the reference charge in the first charge comparison step, the externally supplied power is selected as the usage power for the customer in case the stored power quantity is lower than the reference power quantity and the power quantity demand, through the first and second power quantity comparison steps; ; and if the charge of the supplied power is higher than the reference charge in the first charge comparison step, the stored power is selected as the usage power for the customer in case the stored power quantity is higher than the reference power quantity or the power quantity demand, through the first and second power quantity comparison steps.

Description

【Technical field】 [0001] The present invention relates to a power control device, and a power control method using the power control device, which realize power control in a power supply network based on two-way communication between suppliers and consumers. 【Background technique】 [0002] The Korean power grid is structured as a centralized vertical network system centralized at a central location and regulated by producers. The electricity tariff system is based on a usage-based tariff system and is supplemented with other tariff systems by voltage and by time. A step-by-step system has been applied to the remaining electricity. Likewise, a late-night power schedule is maintained in order to spread out power demand that is concentrated at a specific time. However, such a power system cannot solve global tasks including prevention of global warming, lack of solutions for rising raw material prices, and problems of excess energy consumption control and stable power supply....
