Improper control of grid-connected Voltage Source Converters (VSCs) in harmonically polluted grid results in flowing low order current harmonics into the grid. In other words, the VSC behaves as harmonic load from grid point of view. VSC output filters cannot eliminate these polluted currents, since they are designed for switching high frequency harmonics. From the approaches presented in this regard,...
Microgrid (MG) protection is one of the main challenges in proliferation of microgrids. Due to limited fault current feeding of inverter-based distributed generations (DGs), in islanded operation of MG, protection problems become more complicated; and, therefore, conventional protection strategies cannot be applied. Hence, new protection methods that are applicable in islanded and grid-connected modes...
P-V characteristic of photovoltaic (PV) arrays under partially shaded conditions (PSC) has multiple peaks, and conventional maximum power point tracking (MPPT) algorithms may fail to track the global maximum power point (GMPP) because of their insufficient intelligence in discriminating the local and global peaks. This paper proposes a novel fast MPPT method to achieve GMPP of PV array under all PSCs...
