Doubly Fed-Induction Generator (DFIG) | · Potential reduction of fuel consumption and GHG’s by an amount of 15% - 20% · Requires a low power converter | · Generates important harmonic disturbances · Very sensitive to grid faults · Requires more maintenance due to the presence of rotor brushes | [61] [62] |
Genset-Synchro Generator | · Potential reduction of fuel consumption and GHG’s by an amount of 8% - 12% · Can be adapted or integrated on existing DPG and/or Wind turbine generator · Possibility to maintain voltage and frequency constant at the output of the generator by controlling only the stator speed | · Maximum generator power is limited to 85% - 90% due to the presence of the compensating motor · Requires more maintenance due to the presence of rotor brushes · Harmonics level are higher by an amount of 3% compared to a standard Genset | [56] [57] [58] |
N-Split DPG | · Potential reduction of fuel consumption and GHG by an amount of 25% | · Requires a large space for installation · Requires more maintenance · High capital costs for purchase and for installation | [62] |
DPG with BSS | · Reduction of fuel consumption and GHG by an amount of 5% · Ideal for twining and Hybridization systems such as Solar-Diesel-BSS and Wind-Diesel-BSS | · Batteries management and cost · Requires electronic converters · Not suitable for cold areas | [64] [65] [66] [67] [68] |
