Power supply demand / supply adjusting device, load frequency control device of power system, balancing group device of power system and power supply adjusting method for power system

摘要

Problem to be solved: to reduce the cost while suppressing frequency fluctuation according to load fluctuation.A power supply and demand adjustment apparatus for power systems used to determine an output allocation to a power supply power source constituting a power system is an output distributable upper limit database DB2 which stores functions indicating the relationship between the magnitude of the supply / demand imbalance and the upper limit of output allocation An output distributable upper limit changing section 13 for changing an output distributable upper limit value to the target adjusting power supply per output allocation is provided.Diagram
