OPTIMUM DG ALLOCATION CONSIDERING PROTECTION COORDINATION AND NETWORK PERFORMANCE EVALUATION

Abstract

This thesis introduces two strategies to avoid the miscoordination between recloser and fuse. The first strategy presents an approach to determine the maximum suitable size of a DG that is connected to distribution networks in addition to other keys taken into consideration such as improving voltage profile, reducing fault current and minimize system power loss. The second approach is used to obtain the optimum settings for recloser and fuses in the presence of single/multiple DG units which can coordinate properly with different sizes and location of DGs in the system with suitable time coordination interval
