This paper proposes a new approach to efficiently track the desired maximum power point for photovoltaic systems under partial shading conditions. The power stage architecture achieves fast input current change rate by combining a current-adjustable converter with a few converters operating at a constant input current. By taking advantage of fast current change, the control scheme effectively combines...
A microgrid is an integration of distributed energy sources, loads and energy storage systems. Indeed, energy storage systems are required in order to ensure reliability and power quality because of the intermittent nature of renewable energy sources and changes of load demand. Apart from that, the use of distributed energy storage units provides redundancy to the system and support possible increments...
This paper deals with design and control of a connected wind energy generation system employing a Permanent Magnet Synchronous Generator (PMSG) driven by a variable speed wind turbine feeding single-phase loads. The proposed energy conversion system makes use of asymmetric NPC five level inverter. The dc terminal of the generator connected rectifier is tied to a boost converter for Maximum Power Point...
