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.
