DEVICE FOR CONTROLLING POWER SUPPLY AND DEMAND OF ELECTRIC POWER SYSTEM ACCORDING TO OUTPUT FLUCTUATION OF RENEWABLE ENERGY SOURCE AND METHOD FOR CONTROLLING POWER SUPPLY AND DEMAND OF ELECTRIC POWER SYSTEM USING THE SAME

摘要

According to the present invention, provided is a device for controlling power supply and demand of a power system in accordance with an output fluctuation of a new renewable energy source. The device for controlling power supply and demand of a power system in accordance with an output fluctuation of a new renewable energy source comprises: a data collection unit which collects output data of a new renewable energy source connected to a power system; and a control unit comparing an output amount of the new renewable energy source and a total load amount of the power system to control an operation mode of a variable speed pumping-up power generator in order to maintain power supply and demand of the power system or enable a frequency change of the power system to be maintained within a predetermined range.
