DEMAND ADJUSTMENT SYSTEM FOR POWER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a demand adjustment system for a power system, capable of highly maintaining frequency maintenance capacity at power demand variations.SOLUTION: The demand adjustment system for power system, connected with SOFC 4 as power generation equipment 2B, includes: a first mode for executing output control of an SOFC 4 by only current control of a PCS 5 for control corresponding to an inertia response region of a generator in an output response of the power generation equipment executing power generation by the rotation of a rotating element relative to a load variation in a system power line 1 of a power system; a second mode for executing current control of the PCS 5 for control corresponding to a downstream region of a governor-free region of the generator in the output response and output control of the SOFC 4 by control of a fuel flow to be supplied.SELECTED DRAWING: Figure 2
