摘要：
Power system contain various harmonic loads and nonlinear loads. These loads may be jeopardize distributed generation (DGs) and micro-grids (MGs) operation and create stability problems. In this paper, the effects of various harmonic loads on DC side of three-phase inverter are investigated based on mathematical equations and simulations. Moreover, a new hybridization concept for tackle the negative effects of harmonic loads and nonlinear load is proposed. In this strategy super capacitor (SC) is used for compensate the oscillation that generate by harmonic loads. In addition, proposed strategy improves system performance under load changes and variations. To investigate the effect of harmonics and confirm the proposed method, simulation of a hybrid system have been implemented in MATLAB/SIMULINK environment. The simulation results prove the effectiveness of the proposed strategy.
