In this paper grid is interconnected to Renewable Energy source i.e., Hybrid interconnection of WIND ENERGY & the PV cell. The 3-phase, 4-wire active power filter (APF) which is used as inverter in this paper The inverter is used to act as active power filter (APF), at different voltage i.e., in order to inject the voltage from RES into the grid to reduce the power quality problem to compensate the harmonic content in the total system. The active power filter is of 4-leg in which 3-legs are used to compensate at the 3-phases & the 4th –leg is used to compensate the neutral current. A set of linear and Non-linear loads is used to study the performance of the system with some delay time to study waveforms both in linear & Non-linear loads acting simultaneously or instantaneously. The MATLAB/SIMULATION model of the proposed system & the waveforms is illustrated.

Keywords: Grid, RES, APF, Linear and Non-Linear loads.
