To achieve a more sustainable supply of electricity, using distributed generators (DGs) utilizing renewable energy sources (RESs) is a promising solution. However, emerging renewable energy based DGs into power grids reduces the total inertia of the system, and hence, the power grid dynamics and performance can be negatively affected. To address these issues, several inverter control methodologies have been recently proposed for the DGs, and some efforts have been done for introducing the concept of virtual inertia and better understanding of dynamic characteristics of power networks in the presence of high penetration of DGs and RESs. The present paper emphasizes some significant points on the importance of inverter-based virtual inertia on the grid frequency regulation, dynamic impacts, and new relevant ideas to improve power grids frequency stability and control performance.
