Abstract:
The principal aim of this research is to identify and use the advantages of Z-source
inverter and to develop a reconfigurable architecture for residential microgrid. The
researcher has described the summary of the studies on Z-source inverter and
reconfigurable systems. The distinctive feature of the proposed, reconfigurable,
residential microgrid is the capability to reconfigure microgrid components to
operate as a current source (current controlling mode) and a voltage source
(voltage-frequency controlling mode) and a static synchronous compensator
(STATCOM) (reactive power controlling mode) while replacing the traditional
solar inverter from latest Z-source inverter. Where grid-connected, solar
photovoltaic customers get uninterrupted power supply from their solar system
even at a grid fault, and utility grids can use the same assets to improve the power
quality and use their distribution network when it is idle at night. Then, it improves
the utilization factor of solar photovoltaic system, power quality at the point of
common coupling, and reliable power supply to the loads while increasing
controllability of residential microgrid and taking part grid operations with utility
grid request. Both the customer and the grid owner could get benefits. The
proposed architecture is developed in MATLAB/Simulink platform and results are
discussed to prove the proposed architecture.
