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

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
