Özet
With the extensive utilization of distributed renewable energy sources (RESs), the frequency control in microgrids (MGs) has become a challenging task due to inadequate inertia and damping. Moreover, the control and coordination of these sources require the use of a communication network (CN) that induces time delays (TDs). TDs lead to less efficient operation of the controller and can even destabilize the microgrid if they exceed a permissible delay, known as the stability delay margin (SDM). This study examines the delay-dependent stability (DDS) of an islanded MG, including a virtual inertia and damping (VID) control loop. An analytical method, Rekasius substitution (RS) with Resultant Theory, is proposed to compute SDM. The impact of the integration of VID control on the SDM has been further examined. The results indicate that implementing VID control increases SDMs by 59.22% to 96.32%. Incorporating VID improves the frequency stability of MGs.
