چکیده

In this paper, a novel control method for photovoltaic converter connection to the national grid
is presented, so in addition to the injection control by solar arrays to the grid, this method can
compensate reactive power and harmonics in the load current. The system will be connected in
parallel between the grid and load. The proposed system supplies all load power consumption
(including active power and reactive power) and if less power is produced by the solar array
inverters, the proposed method can be used to compensate the remaining reactive power and
harmonics of load. Using this method, power factor of the system will be equal to unity. Finally, to
verify the performance of the method, a grid-connected photovoltaic system is simulated.
