Renewable energy sources are a reliable alternative to the conventional energy sources. This paper presented an capable of expandable grid-connected distribution generation interconnection of 3 phase 3 wire system for reactive power compensation. The proposed system not only, can control the active power flow but also mitigate the load unbalance and harmonics, and manage reactive power. All of these functions may be accomplished either individually or simultaneously. So the performing an active power balance by controlling the RES voltage level for the whole system. With the proposed approach, to shape the grid currents into sinusoidal currents in phase with the grid voltage waveforms and with an amplitude depending on the power available from renewable sources. On the other hand the load harmonics current will reduced by injecting into the alternating current system harmonic currents with an opposite phase.
