Modeling and Control System Simulation of a Flexible Power Conditioning System with Grid Inertia Support Function
Previous studies on related systems have not considered the impact of power on the rectifier side.Unlike traditional approaches where the double-fed rotor-side inverter is equivalent to a DC source,this paper integrates an improved space vector pulse width modulation(SVPWM)method to extend the power regulation range of the entire system.Building on this,a sys-tem-wide control strategy based on grid voltage orientation is proposed,incorporating the inverter angle as a control variable.Comprehensive mathematical modeling and control system design are carried out for the double-fed motor and its drive system,the inertia energy flywheel,and the grid-side rectifier.Simulation results and system functionality verification demonstrate the effectiveness of the proposed approach,providing a significant theoretical foundation for optimizing and improving the operation of the entire system.
