  • Photovoltaic power plant system
    Patent number: 11228178
    Abstract: A photovoltaic power plant system for power generation, comprising one or more photovoltaic clusters and one or more modular multilevel converters. Each photovoltaic cluster includes a number of photovoltaic strings connected to one or more MPPT DC/DC, converters connected to a common LVDC, bus. Each photovoltaic cluster includes a DC/DC converter including an input connected to the LVDC bus, and an output connected to a MVDC collection grid. Each of the one or more modular multilevel converters includes an input connected to the one or more photovoltaic clusters via the MVDC collection grid and an output connected to a transmission grid.
    Type: Grant

  • Medium voltage direct current power collection systems and methods
    Patent number: 10348093
    Abstract: Unique systems, methods, techniques and apparatuses of a power collection system are disclosed herein. One exemplary embodiment is an MVDC collection system coupled to a utility grid including a collection bus, a plurality of branches coupled to the collection bus, and a branch controller. Each of the plurality of branches include a semiconductor switch coupled to the collection bus, and a DC/DC converter coupled to the semiconductor switch and an LVDC power source. The branch controller configured to determine a fault condition is occurring within the MVDC collection system, determine the location of the fault condition, and isolate the fault condition using at least one of the semiconductor switches and the DC/DC converters.
