Abstract

New ways of generating electricity make possible decentralization of energy sources. This scenario of distributed generation allows efficient management of smaller electricity networks, so called microgrids. Additional advantages include a large reliability and the capability to provide a high quality of service. A strategy to design these microgrids consists on taking advantage of existing distribution network by sectoring the system into a set of microgrids with optimal autonomy. This paper presents a one-step methodology for the optimal design of microgrids based on the virtual segmentation of a distribution system. The proposed method focuses on the optimal allocation and sizing of the distributed generation together with the determination of the virtual cut-set lines to form an optimized set of microgrids. The design methodology was implemented on IEEE 119-bus system, and was also applied to Bella Italia distribution system, a real network located in Santa Fe province, Argentina.
