Towards a simulation platform for islanded microgrids based on grid-forming power converters

Abstract:

This work proposes a simulation approach to emulate islanded MicroGrids (MGs) where the distributed generation units are based on virtual grid-forming power converters working as voltage sources. In this context, the droop method for frequency and voltage is the control scheme used for connecting multiple voltage sources that share the load and maintain the voltage quality. The framework includes virtual elements developed from two Matlab toolboxes: Simscape Power Systems and Truetime. Simscape covers the simulation of power electrical/electronic devices; Truetime facilitates the simulation of dinamically distributed realtime kernels executing control tasks. Like other simulation approaches, this proposal has the benefit to allow the theory to be quickly verified before moving on to experiments that could be difficult, expensive and sometimes dangerous. To test the validity of the proposal, a virtual MG close …
