Synchronous Condensers and Grid-Forming Control for the Integration of Inverter-Based Resources in Weak Grids
… by leveraging synchronous condensers (SC) and grid-forming control. First, it presents an optimization model to find the optimal location and size of SCs, aiming to minimize the total cost of SCs and maintain the strength (measured by short-circuit ratio [SCR]) above a desired value at the …

Design and Evaluation of a Photovoltaic Inverter with Grid-Tracking and Grid-Forming Controls
… of a virtual-synchronous-machine- (VSM-) based control to a conventional 250-kW utility-scale photovoltaic (PV) inverter. VSM is a recently-developed control scheme which offers an alternative grid-synchronization method to the conventional grid-tracking control scheme, which is based on the dq …
