Abstract

The invention discloses a high voltage flywheel combined chemical battery energy storage system for peak and frequency adjustment of power grid, and belongs to the fields of power grid peak and frequency adjustment. The system comprises the national power grid, an electric energy stored flywheel battery control unit, an electric energy stored chemical battery control unit, and a master control system for monitoring the demand state of the national power grid and controlling the flywheel battery control unit and the chemical battery control unit; the national power grid emits a control signal to the master control system according to the peak value demand state; the flywheel battery control unit receives the control signal of the master control system and carries out electric energy charging / discharging and frequency adjustment on the national power grid; the chemical battery control unit receives the control signal of the master control system and carries out electric energy charging / discharging on the national power grid; and the master control system realizes peak and frequency adjustment by means of control of the flywheel battery unit. Deep peak adjustment can be realized by controlling the chemical battery unit, and residual electric energy can be stored for supplement electric energy in the peak period of the power grid via the electric energy storage feature.

Description

technical field [0001] The invention relates to the technical field of power grid peak regulation and frequency regulation, in particular to a high-voltage flywheel combined chemical battery energy storage system applied to power grid peak regulation and frequency regulation. Background technique [0002] In recent years, with the significant changes in the load structure of the power grid and the rapid growth of the installed capacity of the power grid, the peak-to-valley difference of the load in the daily operation of the power grid is increasing, and the ability of the power grid to curb wind is insufficient. Difficulty in peak shaving has become the most prominent problem in power grid operation. [0003] At present, the peak regulation of the power grid mainly relies on the electric heat storage boiler and the electrode boiler energy storage peak regulation technology. , there are disadvantages such as large equipment footprint, high construction and maintenance costs...
