Title:
DISPERSED POWER SUPPLY APPARATUS
Document Type and Number:
Japanese Patent JP2014183601
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersed power supply apparatus capable of achieving miniaturization and cost reduction of power storage equipment configuring a dispersed power supply and a power conversion apparatus, as well as continuous operation even when a sudden change in load or solar radiation occurs.SOLUTION: The dispersed power supply apparatus is composed of a first dispersed power supply unit 8 with a solar battery 1 and a first power conversion device 3 and a second dispersed power supply unit 9 with power storage equipment 2 and a second power conversion device 4. Power control means 42 of the second dispersed power supply unit 9 controls an AC output voltage phase so that a charge/discharge power detection value follows a charge/discharge power command value, thus controlling generation power of the first dispersed power supply unit 8 and charge/discharge power of the second dispersed power supply unit 9.
