Abstract :
DGs connected to distribution systems are increasing in size and number. Intentional islanding are proper alternatives to increase the reliability of end load in the network with does not access to any other branch. In other conditions these loads experiences permanent interruption. in load restoration operation, islanding is so important in the presence of DGs. Islanding is occurred when a part of distribution network is supplied only from DG sources. A new algorithm for distribution load restoration in the presence of DGs is presented in this thesis. the proposed approach minimizes the load interruption cost in restoration process based on Tabu search method. In this algorithm the maximum load with the most level of importance is restored in minimum time by reconfiguration, islanding and finally load shedding. Energy storage units and the location of synchronizing devices are considered in this thesis. The algorithm is implemented on a 32-bus test system and numerical results are presented.
