The measurement layer of the Virtual Synchronous Generator operation in the field test

Abstract
In order to have comparable results for several algorithms designed for Virtual Synchronous Generators (VSG), a set of performance indicators have been derived from the test field operation. The uncertainties budget of the VSG control algorithm is also derived from measurement data and grid parameters. The frequency measurement and rate of change of frequency estimation determine the VSG algorithm performance. However, in grid connected mode, it is not possible to highlight the VSG contribution to the grid inertia, due to system size differences. Therefore, in this paper, results from island mode operation are also included.
