Title:
ELECTRIC POWER SUPPLY SYSTEM, CONTROL DEVICE FOR ELECTRIC POWER SUPPLY SYSTEM, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/110276
Kind Code:
A1
Abstract:
The present invention achieves an electric power supply system that can be inexpensively operated. The electric power supply system has: an electric power supply facility (5, 6) that is connected to a load facility (9) via an electric power system (2) and is capable of increasing/decreasing output power thereof on the basis of an external output command (PBATT (t), PEG (t)); and a control device (4). The control device (4) has: a system inertia-absorbed electric power calculation unit (416) for calculating system inertia-absorbed electric power (ΔPI (t)) on the basis of system inertia (H) pertaining to the electric power system (2) such that the frequency variation range of the electric power system (2) falls within a predetermined range (±ΔfLIM); and a signal input/output unit (42) for sending a value obtained by subtracting the system inertia-absorbed electric power (ΔPI (t)) from deficient/surplus electric power (PDP (t)), that is, a deficiency or surplus of electric power in the electric power system (2), to the electric power supply facility (5, 6) as the output command (PBATT (t), PEG (t)).
