Title:
分散電源用制御装置および集中型電圧制御システム
Document Type and Number:
Japanese Patent JP5705076
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a distributed power supply control device which can properly control the reactive power of a distributed power supply in order to effectively utilize the generated electric power of the distributed power supply and stabilize the voltage of an electric power system, and a centralized voltage control system.SOLUTION: A distributed power supply control device according to the present invention comprises: a generated electric power statistical processing unit 102 which calculates a maximum increment width and a maximum decrement width on the basis of the maximum and minimum generated electric power of a photovoltaic power generator 3 until before a prescribed time and its previously generated electric power, and statistically calculates an average value and a standard deviation of maximum change widths on the basis of the maximum increment width and maximum decrement width for a prescribed past period; a maximum generated electric power forecast unit 103 which forecasts the maximum generated electric power of the photovoltaic power generator 3 until after a prescribed time on the basis of the current generated electric power and the average value and standard deviation; and a reactive power controllable amount forecast unit 104 which forecasts a maximum controllable amount of reactive power until after a prescribed time on the basis of the maximum generated electric power and the capacity of an inverter 302.
