Title:
DISTRIBUTED POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2010110088
Kind Code:
A
Abstract:

To provide a distributed power supply system that achieves high-accuracy load-following operation when executing operation control of each distributed power supply.

The distributed power supply system is configured such that a distributed power supply having the highest load-following performance is connected to the vicinity of a connection point with a commercial system in order to reduce a load on the commercial system by integratively controlling a plurality of distributed power supplies each having different following performance with respect to load variations. The distributed power supply system includes a power measuring means for measuring power of a secondary-side position of the connection point, and a control means for controlling output power of the distributed power supply, having the highest load-following performance, on the basis of the power value measured by the power measuring means.
