Combined Operation of Renewable Energy Sources and Active Power Filter: A Review

Distributed generation (DG) such as solar and wind systems have attracted energy sectors as an alternative sources to produce electrical energy either in grid-connected or islanding mode. The increase of DGs penetration cause a power quality problems and it necessary to use power conditioners such as active power filters to mitigate these problems, since passive filter lack the ability to completely mitigate power quality problems in presence of nonlinear loads. This paper gives an overview of the main topologies of the combined operation of DGs based on photovoltaic, wind turbines and active power filters.
