ntr Secure control mechanism for distributed photovoltaic system By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT A system for controlling photovoltaic electricity production equipment having photovoltaic modules each equipped with a DC/DC microconverter connected to a DC bus, a DC bus manager, and an inverter for converting the direct current from the photovoltaic panels into alternative current intended for an electrical distribution network. Power is injected into the DC bus when the voltage of the DC bus is less than a minimum voltage until the minimum voltage is reached. Each of the microconverters injects a maximum power from the photovoltaic modules into the DC bus when the voltage of the DC bus is between a first voltage and a second voltage. The injecting of power from the photovoltaic modules into the DC bus is stopped when the voltage of the DC bus is less than a low threshold voltage or greater than a high threshold voltage.
