Title:
ELECTRIC POWER CONVERSION SYSTEM AND ELECTRIC POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/176776
Kind Code:
A1
Abstract:
A plurality of electric power conversion devices 10a, 10b, 10c are respectively connected to a plurality of distributed power sources 2a, 2b, 2c. The plurality of electric power conversion devices 10a, 10b, 10c are connected in parallel to a receiving point N1 of an electric power system 4, and can supply alternating-current power to a load 3 connected to the receiving point N1. Each of the plurality of electric power conversion devices 10a, 10b, 10c autonomously performs droop control of output, under a linear function of y = ax + b, where x is a measured value of bidirectional current or bidirectional power from the receiving point N1 to the electric power system 4, y is an electric current instruction value or an electric power instruction value for the electric power conversion devices 10, a is a constant, and b is a variable. The variable b is variably controlled in accordance with the measured value of bidirectional current or bidirectional power.
