This paper models and analyzes a power distribution system with sources connected through inverters. The stabilizing effect of generator rotational inertia is emulated through inverter droop control logic. We model the nonlinear dynamics of the system with multiple distributed droop inverters using dynamical phasors. Linearizing the system around the steady-state, we construct closed-loop transfer...
A small-signal model is used to design the controller parameters of the conventional Power Factor Correction (PFC) converter. The dynamics of the converter is nonlinear, therefore, it is hard to derive desirable performance. Genetic algorithm is used to optimize the control parameters of PFC converter in this paper, by this way, the quasi-optimal control parameters can be obtained with the predefined...
This paper overall analysis seady state and transient condition mathematical model for STATCOM direct-current side electric capacity voltage, unifies the STATCOM main circuit's design simultaneously, calculated electric capacity voltage movement scope, waves and electric capacity voltage size which are under various operating modes for this equipment. In this paper applies to low-pressure area which...
