I. Background

• The increasing use of Renewable Energy Sources (RES) such as Solar Cell and Wind Turbine

• Power convertion from DC to AC• The using of non linear power electronic

caused harmonic, so the filter is necessary to reduce distortion.

• The exploiting harmonic so here we try to take benefit from

II Basic Theory

• RENEWABLE ENERGYWIND TURBINE (PMSG)

• PV – SOLAR CELL

Powe Electronic

• RECTIFIER AC - DC

• CHOPPER DC- DC

• Inverter

Renewable Connection to Grid

Harmonic

• The disturbance in power system because use of Non Linear component such as power electronic converter.

• In this case, Inverter is the main part to supply energy.

• A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency
