Title:
POWER CONDITIONING SYSTEM AND POWER CONDITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/061048
Kind Code:
A1
Abstract:
A power conditioning system according to the present embodiment is provided with: a first power conditioning unit that performs, by power charge and discharge, power conditioning between a power generation unit and a load unit via a power transmission unit for transmitting generated power of the power generation unit to the load unit; a second power conditioning unit that performs power conditioning by power charge and discharge having a faster control response time than the first power conditioning unit, via the power transmission unit; a first control unit for performing control to decrease the difference between a power generation value of the power generation unit and a power consumption value of the load unit, with respect to the first power conditioning unit; and a second control unit. The second control unit decreases the difference between the power generation value of the power generation unit and a difference value obtained by subtracting a discharge power value of the first power conditioning unit from the power consumption value of the load unit, in a state in which the power consumption value of the load unit is larger, and in a state in which the power consumption value of the load unit is smaller, performs, with respect to the second power conditioning unit, control of the power charge and discharge for decreasing the difference between the generated power value of the power generation unit, and an addition value obtained by adding the power consumption value of the load unit and a charging power value of the first power conditioning unit.
