Current improvement of a grid-connected photovoltaic system under unbalanced voltage conditions
This paper discusses the performance of a large-scale grid-connected photovoltaic system (GCPS) under unbalanced voltage sag conditions in the grid. By applying the droop control to address the low-voltage-ride-through (LVRT) capability, the output ...

Grid sequence detector based on a stationary reference frame
This paper proposes a new three-phase positive sequence detector. The scheme is based on a stationary reference frame and a Moving Average Filter (MAF) that guarantees the complete cancellation of harmonics and grid imbalances. The performance of the MAF

Moving Average Filter Based Phase-Locked Loops: Performance Analysis and Design Guidelines [PDF]
IEEE Transactions on Power Electronics, 2014 The phase locked-loops (PLLs) are probably the most widely used synchronization technique in grid-connected applications. The main challenge associated with the PLLs is how to precisely and fast estimate the phase and frequency when the grid voltage is ...
