چکیده

An islanded microgrid (MG) including low-inertia converter-based distributed generations (DGs) is subjected to instability. The virtual inertia concept was proposed alleviate the stability issues by imitating synchronous generators behavior. This paper spotlights on optimization of generator (VSG) parameters and impedances (VI) in MGs using particle swarm (PSO). A small-signal model for MG developed at first. permissible ranges (J) damping (D) based are scrutinized afterwards. Moreover, VI considered lower reactive power mismatch between converters. Finally, considering permitted intervals these parameters, an method objective function defined calculate VSG MG. enhances MG, decreases current overshoot minimizes mismatches. Simulation results drawn “VSG + VI” control include three scenarios. effectiveness comparison with “droop” control, “droop VI”, “non-optimal ” verified through simulation studies.

Designing a new robust control for virtual inertia control in the microgrid with regard to virtual damping

Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...

Virtual synchronous generators: A survey and new perspectives

In comparison of the conventional bulk power plants, in which the synchronous machines dominate, the distributed generator (DG) units have either very small or no rotating mass and damping property. With growing the penetration level of DGs, the impact of low inertia and damping effect on the grid stability and dynamic performance increases. A solution towards stability improvement of such a gr...
