【 摘 要 】

The current context of microgrids shows a considerable and unprecedented increase in distributed generation. A microgrid is defined as a network of electricity users composed of distributed generators, loads and storage elements able to operate as a single entity connected or isolated from the main grid. However, the microgrids have usually low short-circuit power capabilities due to the distributed generators composed of electronic converters, which makes the system very susceptible to power quality problems. This article presents an analysis of the series hybrid active filter connected to a centralized AC microgrid, under low power quality issue operation in islanded and grid-connected modes. The paper evaluates the series hybrid filter performance in harmonic compensation and resonance damping capability through simulation analysis. The results show that a series hybrid filter is capable of enhancing the microgrid power quality, requiring a low nominal capacity active filter.
