Patent ID: 8624439

Claim:
A method for managing a system for generation of electric power, the system including at least one direct current (DC) source which delivers at a DC source output an electric power subject to fluctuations, and a plurality of inverters comprising a respective control unit and having a respective inverter output and a respective inverter input connected to said DC source output, and wherein each of the inverters is functional to transform the electric power at the inverter input into ac electric power at the inverter output with controlled frequency and voltage, the method comprising the steps of: selecting one of said inverters as a master unit and the remaining inverters as slave units; performing, via said master unit, a maximum power point tracking algorithm to generate a power modulation control signal via said master unit; and using said power modulation control signal to concurrently control and manage in parallel the master unit and at least an active one of the slave units to vary the power absorbed by said master unit and by said at least one active slave unit, so that each of said master unit and said at least one active slave unit delivers a variable power output that tracks the fluctuations of the power at the output of said direct current source by tracking a maximum power point via the maximum power point tracking algorithm performed by said master unit.
