Under the precondition that large capacity Distributed Generation (DG) allows multi-feeder access system and all the DGs are absorbed, it is very necessary for the planning of the smart grid to coordinate the relationship between the position of each access point and the users' demand. This paper coordinately considers the planning and design requirements of the distributed photovoltaic (PV) power generation as well as the reconfiguration of power distribution systems with DG and proposes a novel method for feeder-selecting and sizing of the distributed PV power generation. Under the condition in which the total capacity of the distributed PV power generation has been determined and the feeder and capacity of each access point haven't yet been determined, a second-order cone programming planning model with the constraint of the Distflow equations is developed to get the optimal planning program for the distributed PV power generation access. And at the same time the optimal reconfiguration results of the power distribution system under the effect of the new DG are also obtained. Finally the correctness and validity of the proposed method are verified by results of calculation example.
