In recent years, applications of power electronics in power systems have increased significantly, particularlary, in renewable energy harvesting and for addressing many of the power qulaity problems at distribution systems. The momentum behind increased adoption of power electronics in renewable energy conversion systems stems from their compactness and increased control flexibilities.

As large renewable power plants tend to be located far from consumption centres, integration of the power collected from these power plants represent a major challenge. For example, the electrical outputs of these renewable power plants couldbe DC or AC voltage with magnitude and frequency which are incompatible with the AC grids. Therefore, power electronic interfacing is needed to decouple the AC grids from the power plants, control active and power exchange with AC grid, and assist renewable power plants to ride-through different AC and DC network faults.

The main objective of the special issue is to provide a platform for researchers, and experts from academia and industry to discuss, share, exchange, and provide ideas, and also to identify unforeseen challenges and problems to be solved and worthy of further investigations. Therefore, the authors are invited to submit an abstract to this special uses, provided the subject of the abstract falls within one of the following areas.
