Grid synchronization stability issues and subsynchronous oscillations between synchronous generators exist in electrical power systems. Three-phase voltage-source converters (VSCs) are being installed more and more in the grid to improve efficiency or to utilize renewable energy sources. The same stability issues between VSCs are also reported and analyzed using a small-signal model of phase-locked...
Grid synchronization instability issues and low frequency oscillations between synchronous generators exist in electrical power system. This kind of stability issue happens between paralleled power converters is also reported. Analysis based on small-signal model of inverters with phase-locked loops (PLL) has been proposed. Different from that approach, which needs detailed inverter and controller...
