SYSTEM AND METHOD FOR CONTROLLING VOLTAGE REACTIVE POWER

Title:

SYSTEM AND METHOD FOR CONTROLLING VOLTAGE REACTIVE POWER

Document Type and Number:

Japanese Patent JP2010136600

Kind Code:

A

Abstract:

To provide a system and a method for controlling a voltage/reactive power in consideration of a control delay in a voltage control apparatus.

A demand forecaster 4 forecasts future effective and reactive powers at each substation on the basis of the effective and reactive powers measured in each substation. An optimizing part 6 searches the optimum control variables of facilities for each substation on the basis of the future effective and reactive powers at each substation by using a meta-heuristic technique.
