Abstract :

In this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. The system will be connected inparallel 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 arrayinverters, the proposed method can be used to compensate the remaining reactive power andharmonics of load. Using this method, power factor of the system will be equal to unity. Finally, toverify the performance of the method, a grid-connected photovoltaic system is simulated.
