A load transfer scheme of radial distribution feeders considering distributed generation

Abstract

This work proposes a load transfer scheme for radial distribution feeders with distributed generation units. A distribution feeder may be operated with distributed generation units in parallel. Conventional load transfer schemes do not consider this kind of operating condition. Hence, they are not suitable for power distribution systems including distributed generation units. In this paper, the load transfer scheme considering distributed generation is presented first. Then the difference between the proposed scheme and conventional one is explored. Second, the effects of distributed generation units on the operating states of supported distribution feeders after load transfer are analyzed via computer simulation. Final, a test case is carried out to examine the function of the proposed load transfer scheme.
