Systems and method for electrical power distribution in solar power plants

A power generation architecture for a photovoltaic power plant, said architecture comprising:

• a plurality of photovoltaic blocks, each photovoltaic block comprising:
• a plurality of photovoltaic groups, each photovoltaic group comprising:
• a plurality of photovoltaic strings, each photovoltaic string operable to output low voltage, direct current (LVDC) electrical power at a string output, wherein each of the plurality of photovoltaic strings include a plurality of photovoltaic modules connected in series;
• and
• a direct current (DC) to DC power converter having a converter input and a converter output, said converter input electrically coupled to said string output of each photovoltaic string, said DC to DC power converter operable to convert said LVDC electrical power to medium voltage, direct current (MVDC) electrical power at said converter output;
• and
• a combiner having a combiner input in electrical communication with the converter output of each of said plurality of photovoltaic groups and a combiner output, said combiner operable to combine said MVDC electrical power received at said combiner input to produce a block output at said combiner output;
• and
• a MVDC collector having a collector input and a collector output, said collector input electrically coupled to each combiner output and operable to combine each block output;
• wherein each photovoltaic group comprises only four photovoltaic strings.
