Hybrid reactive power compensations for power factor correction in distribution networks with DG

The converter-connected distributed generation can provide the active power factor correction similar to using power conditioners. The hybrid reactive power compensations, using distributed generation and switched shunt capacitors in the coordinated manner, are implemented to deal with the change of power factor in the network. The study found that this approach can improve power factor controllability in the distribution networks effectively. The power factor control performances are demonstrated under various operating scenarios using the test system implemented in DIgSILENT PowerFactory.
