Variable parameter frequency modulation methods, devices and electronic equipment

Abstract

This application provides a variable parameter frequency regulation method, apparatus, and electronic device, relating to the field of power system technology. The method includes: acquiring the load power change of a doubly-fed induction generator (DFIG) with a flywheel energy storage unit; obtaining real-time parameter optimization constraints based on the load power change, a time-delay frequency response model, preset frequency constraints, the expression for the minimum frequency point, and the steady-state frequency expression; the time-delay frequency response model characterizes the time-delay dynamic relationship between the frequency change and the load power change within the DFIG with a flywheel energy storage unit; obtaining a target droop coefficient and a target inertia coefficient that meet the real-time parameter optimization constraints through iterative calculation; and sending the target inertia coefficient and target droop coefficient to the DFIG with a flywheel energy storage unit, so that the DFIG with a flywheel energy storage unit determines a compensation power value based on the target inertia coefficient and target droop coefficient, and adjusts the power according to the compensation power value. This achieves safe and rapid primary frequency regulation with variable parameter optimization control.
