Power systems are going through a paradigm change from centralized generation to distributed generation and further on to smart grids. More and more renewable-energy …
Grid-connected renewables are increasingly developed in recent years, eg wind turbine systems and photovoltaic systems. Synchronization of the injected current with the grid is …
In this paper, we explore a new approach to synchronization of coupled oscillators. In contrast to the celebrated Kuramoto model, we do not work in polar coordinates and do not …

Inspired by induction machines working principles, this paper presents the idea of phase- locked-loop-less (PLL-less) operation of grid-connected voltage source converters (VSCs) …
Synchronization is a crucial aspect in grid-tied systems, including single-phase photovoltaic inverters, and it can affect the overall performance of the system. Among prior-art …
