Research on Location and Capacity Determination Method of DG in Rural Distribution Network Based on BFOA Algorithm

In the face of high network loss and low voltage power supply problems caused by new energy access to rural distribution network, a distributed photovoltaic point and capacity scheme was established to improve voltage and network loss. The distributed PV investment cost, loss cost, power purchase cost and operation and maintenance cost are minimized as the planning model. A distributed generation capacity determination method based on bacterial foraging optimization algorithm (BFOA) is proposed. The optimal capacity of DG is obtained by using BFOA algorithm. An example is given to verify the economy of the proposed planning model, the effectiveness of the optimization scheme to improve voltage quality and network loss, and the accuracy of the algorithm.
