Electrical power systems having reactive power and harmonic support components

An electrical power system connectable to a power grid, comprising:

• a cluster of electrical power subsystems, each of the electrical power subsystems comprising a power converter electrically coupled to a generator having a generator rotor and a generator stator, each of the electrical power subsystems defining a stator power path and a converter power path for providing power to the power grid, each of the electrical power subsystems further comprising a transformer;
• a subsystem breaker configured with each of the electrical power subsystems;
• a cluster power path extending from each subsystem breaker for connecting the cluster of electrical power subsystems to the power grid;
• and
• a reactive power compensation inverter electrically coupled within one of the electrical power subsystems between the corresponding generator and the corresponding transformer, the reactive power compensation inverter including a power source, first and second switching elements in series with each other, and a capacitor positioned between the power source and the first and second switching elements such that the reactive power compensation inverter increases the reactive power level in the electrical current flowing through at least one of the corresponding stator power path or the corresponding converter power path.
