Emerging Converter Topologies and Control for Grid Connected Photovoltaic Systems

Continuous cost reduction of photovoltaic (PV) systems and the rise of power auctions resulted in the establishment of PV power not only as a green energy source but also as a cost-effective solution to the electricity generation market. Various commercial solutions for grid-connected PV systems are available at any power level ranging from multi-megawatt utility-scale solar farms to sub-kilowatt residential PV installations. Compared to utility-scale systems the feasibility of small-scale residential PV installations is still limited by existing technologies that have not yet properly address issues like operation in weak grids opaque and partial shading etc. New market drivers such as warranty improvement to match the PV module lifespan operation voltage range extension for application flexibility and embedded energy storage for load shifting have again put small-scale PV systems in the spotlight. This Special Issue collects the latest developments in the field of power electronic converter topologies control design and optimization for better energy yield power conversion efficiency reliability and longer lifetime of the small-scale PV systems. This Special Issue will serve as a reference and update for academics researchers and practicing engineers to inspire new research and developments that pave the way for next-generation PV systems for residential and small commercial applications.
