ECONOMICAL LOAD DISTRIBUTION METHOD OF GENERATOR, ECONOMICAL LOAD DISTRIBUTION DEVICE OF GENERATOR AND ECONOMICAL LOAD DISTRIBUTION SYSTEM OF GENERATOR

摘要

PROBLEM TO BE SOLVED: To realize accurate economical load distribution of a generator so as to satisfy a demand-and-supply balance and various constraints without being influenced by change of a starting/stopping plan of a generator.;SOLUTION: When a generator starting/stopping plan 22a is calculated based on a demand prediction value 21a for a long term (steps 101, 102) and a generator output value 23a is output based on a demand prediction value 21b for a short term (step 103), in a case where change occurs in the number of the generators for activation in a calculation segment of the generator output value 23a (step 104), the generator output value 23a is calculated again before and after the change (step 107). When there is deviation from constraints (step 108), the change point is corrected to a point before or after thereof (step 109), the generator output value 23a is calculated again (step 110), and the generator output value 23a having minimum deviation from the constraints is output as an optimum value (step 111).;COPYRIGHT: (C)2012,JPO&INPIT
