Load frequency control capacity shortage detection system, method and program for wind power generation

摘要

PPROBLEM TO BE SOLVED: To easily and accurately predict a shortage of load frequency control capacity to a wind power generation variation. PSOLUTION: This system has a wind power generation quantity maximum variation calculating part for calculating maximum variation data on a wind power generation quantity predicted in a predetermined specific time from a maximum value of wind power generation quantity prediction data and wind power generation quantity variation prediction data by using the wind power generation quantity variation prediction data preset as data for expressing a time variation prediction value of a wind power generation quantity determined from the past measuring result by extracting the maximum value among these from the wind power generation quantity prediction data for indicating the wind power generation quantity predicted in a predetermined period from present time, and a load frequency control capacity shortage detecting part for detecting that load frequency control capacity is insufficient when determining that the wind power generation quantity maximum variation data is larger than load frequency control capacity data by comparing the wind power generation quantity maximum variation data with the load frequency control capacity data for expressing the load frequency control capacity capable of absorbing a variation in a present wind power generation quantity.
