  • Publication number: 20240097454
    Abstract: Disclosed are an emergency control method and system based on source-load-storage regulation and cutback. According to the method, output power of power generating sources is regulated according to a power regulating quantity and a frequency regulation requirement, an output power compensation and output frequency of each power generating source are maintained within permissible ranges, so that a balance between power supply and demand of a power distribution network is maintained; and standby energy-storage power stations are used to make up a power gap, and an external power supply system is used to assist in making up a power deficiency, so that large load disturbance can be handled make up the power gap.
