Described herein is a system for generating electric power, comprising: an electric-power source () having a preferential point of operation; a double-stage inverter (A,B), which transfers the energy from said source to an external a.c.-voltage electrical network (); a block () for identification of the preferential point of operation, which supplies a reference signal according to the conditions of operation of the electric-power source and to the preferential point of operation of said source; a corrector block (), provided for setting the parameter for control of the boost converter (A) of the double-stage inverter (A,B) as a function of the reference signal and of a signal of actual operation of said electric-power source, and for maintaining the source in the proximity of the preferential point of operation.

System for producing electric power from renewable sources and a control method thereof

An electrical power supply system connected to an electrical grid, includes at least one source of electrical power, an inverter which receives power from the electrical source and delivers power to a local load, and a connection to the electrical grid. The system also includes a control unit for controlling the inverter, which interrupts the delivery of power by the inverter when at least one electrical parameter of the system exceeds a threshold value. The system also includes anti-islanding logic which detects at least one symptom of an islanding condition of the system and, when the symptom is detected, to cause a variation in the power level delivered by the inverter.
