VOLTAGE ADJUSTMENT DEVICE, AND VOLTAGE ADJUSTMENT METHOD

Title:

VOLTAGE ADJUSTMENT DEVICE, AND VOLTAGE ADJUSTMENT METHOD

Document Type and Number:

Japanese Patent JP2015042130

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To make it possible to adjust voltage of a power line so that a voltage value of the power line is within a predetermined range.SOLUTION: A voltage adjustment device for adjusting voltage of a power line to which a power load and a dispersion type power supply for supplying power to the power load are connected comprises: a first calculation unit for calculating correlation data showing correlation among an actual power generation amount of the dispersion type power supply at first time, an actual power generation amount of the dispersion type power supply at second time after the first time, and a weather result at third time corresponding to the second time; a second calculation unit for calculating a prediction power generation amount of the dispersion type power supply at fifth time after fourth time which is after the second time, on the basis of an actual power generation amount of the dispersion type power supply at the fourth time, weather prediction at sixth time whose relation with the fifth time is similar to relation between the second time and the third time, and the correlation data calculated by the first calculation unit; and an adjustment unit for adjusting the voltage of the power line so that the voltage value of the power line at the fifth time is within a predetermined range, on the basis of a result of the calculation by the second calculation unit.
