Abstract: Based on compound power quality concept, this paper proposed a compound harmonic, negative and reactive current compensation strategy for harmonic current, load imbalance and low power factor issues in smart distributed grid. Key factors are presented in detail. Corresponding three phase four line APF-STATCOM simulation and experimental tests and field operation results verify the compound control and compensation concept.
