Droop based DG allocation in weakly meshed autonomous microgrid

摘要

The rising renewable based power penetration in the conventional distribution systems have popularized the concept of autonomous microgrids. However, frequency (f) and voltage (V) deviations are major concern due to intermittency of load and renewable generations. The droop based DGs can supply the growing load but require an optimal placement and an optimal droop coefficient so that their allocation does not cause f and V deviations beyond standard limits. In the present work, optimal droop-based DGs placement and its corresponding optimal droop coefficient calculation has been done to supply rising loads considering minimization of f and V deviations. The analysis has been conducted on standard IEEE-33 weakly meshed distribution network which has been modified as autonomous microgrid. The results have been obtained for various load levels and valuable conclusions have been drawn in the end.
