چکیده :

Microgrids (MG) are suffering from devastative effects of the total harmonic distortion (THD) due to the low inertia compared with the conventional grids. Not only does THD affect the power quality but also increases the load sharing error which in turn could lead the MG to an unstable condition. In this way, the need for compensation algorithms that can overcome the barriers alongside this problem is felt more than ever. In this paper, a compensation algorithm that is inspired by active power filters performance for non-linear load based on the instantaneous power theory in frame is proposed to compensate the effects of non-linear loads on droop control and to prevent instability of islanded MGs. Further, an optimization procedure is proposed to find the optimal coefficients of the proposed algorithm.
