Grid And Islanded Operation Of A DG Inverters In Microgrid.

      Аннотация: To overcome all power quality problems uses different power conditioning devices. Such as like active power filters, uninterruptible power supplies, dynamic voltage restorers and unified power quality conditioners are protected their consumers loads and protects the system against the power quality problems. This project represents the micro source devices are connected to the utility grid through dc to dc converters and voltage source inverters at the point of common coupling (PCC). At point of common coupling different electrical loads are connected to. The proposed micro grid consists of a photovoltaic array, proton exchange membrane fuel cell and lithium ion storage battery. The photovoltaic array operates main generation unit of the micro-grid. During the sunless hours proton exchange membrane fuel cell operates the main generation unit. The lithium ion storage battery is implemented to operate the peak shaving during the grid connected operation and islanded operation.
