This paper presents a modified overcurrent protection system to overcome the break points of a parallel distribution feeder protection. For realizing an appropriate protection setting, two concepts are introduced, and their performance is evaluated. These concepts are the adaptive coordination exploiting smart grid information and the modified coordination methods. The modified coordination is adjusted with changing of the contemporary worst fault point. A comparative study is done between the adaptive, modified, and conventional coordination concepts. For investigation purposes, a 11 kV distribution feeder is modelled using the Matlab/Simulink package. The results provide evidence of the efficacy of the proposed modified coordination concept for parallel distribution feeders.
