Of particular interest to grid-tied operation are those controllers that can mimic the inertial behavior of the conventional synchronous machines since the decrease of inertia will pose a serious issue in future power grids. These controllers are called VSM - Virtual Synchronous Machines, a family the synchronverter control concept is part of. In this paper we strive for augmenting the foundations of the synchronverter control and parameter tuning method already laid down in [1] by introducing the filter capacitor and the resistances into the small-signal model. Using parameters determined based on small-signal stability calculations we show how the synchronverter is capable of islanded and grid-connected operation, synchronizing to the grid via a synchronizing impedance. The controller is tested on a power hardware-in-the-loop (PHIL) simulator with an emulated external grid capable of giving frequency response. Simulation results indicate that the transfer from islanded to grid-connected operation of the synchronverter is seamless after a fast synchronization, while the controller can help in the frequency containment process (FCP).

These problems cannot be handled economically effective with traditional network operation and maintenance solutions. Aim of this paper is to give an expert analysis in consideration of possible new technologies from system operator point of view bearing in mind the regulatory environment. Analytical methods and simulation were used to evaluate the effects of these technologies and trends. 14 network effects and 9 different technologies were examined. As a result a revised microgrid definition will be introduced and 5 proposed interventions are formulated. © 2019 IEEE.
