Resumo

The electric power sector due to the great expansion of distributed generation has been undergoing many transformations. Within this context a new concept is being widely discussed: the microgrid. A microgrid is formed by a set of electrical loads, generation sources and energy storage elements, and can operate in grid-connected and islanded mode. However, in islanded mode a microgrid has a low short-circuit power, due to the presence of distributed generators formed by electronic converters, which can make the network susceptible to Power Quality (PQ) problems. In this paper is evaluated by means of simulations the operation of a series hybrid filter in AC microgrid that operate in islanded mode. The main results show that the proposed filter is effective for improving the PQ, with an active filter nominal power equal to 6.64% of the microgrid load.
