Dynamic Performance Evaluation of Inverter Feeding a Weak Grid Considering Variable System Parameters

Interfacing a weak grid imposes challenges on distributed generators (DGs). These include transient frequency and voltage dynamics that can destabilize the system. Accordingly, this paper investigates stiffness based different scenarios of feeding DG connected to grid. Moreover, dynamic effects physical control parameters system’s stability are deeply analyzed evaluated. Specifically, complete mathematical models graphical representation carried out precisely examine impact system performance DG. Therefore, stable deployment renewable energy resources into power networks be achieved as well an efficient robust DGs ensured when grids. The obtained results show importance performed study in optimal sizing designing output filter inverter tuning dynamics. As result, proper design accurately considering all factors affect performance. also conducts detailed elaborated analyses simulations evaluate PI-controlled RC damped proposed interfacing significantly extend integration microgrids without requiring complex schemes or oversized components.
