Micro-grids Resilience Enhancement Using Self-healing Capability

摘要

Active distribution networks operation in islanding mode is one of the concerns of todays power industry operators due to the growth of distributed generations. In addition, it is essential to increase distribution networks resilience in the islanding mode. By constructing microgrids from islanded network based on the self-healing concept, the resilience of remaining distribution network will increase. In this paper, an optimal load shedding algorithm is first implemented due to the amount of available DGs. Then, the active network is divided into a number of microgrids with various boundaries. Two index of self-sufficiency and reliability are used for constructing the microgrids. Finally, the results are tested on IEEE 69 bus distribution system.
