Distributed energy resources network connection considering reliability optimization using a NSGAII algorithm.
Trabalho apresentado confer锚ncia IEEE CPE-POWERENG, 4 a 6 de abril de 2017, C谩diz, EspanhaDistributed Energy Resources (DER) has been
widely introduced in distribution networks in response to the
increase of environmental awareness of the consumers. The
benefits with the use of DER are increased with network
reconfiguration, but in some countries exists the impossibility of
island operation as well as the obligation to buy all the electricity
generated. These limitations, in a network fault situation, causes
a waste of resources, because of the unavailability of the DER.
On other hand, the location of DER connection under the context
of the improvement of the reliability indexes has not been
studied. Thus, this paper will propose a multi objective
optimization of the location of DER connection considering the
switching devices placement to increase network reliability and
availability of DER, minimizing at the same time the investment
in equipment in a no island operation environment. For the
resolution of the proposed formulation, it will be used the multi
objective algorithm NSGA-II (Fast Non-dominated Sorting
Genetic Algorithm). The formulation of the problem also
considers a composite index made up of DER and interruption
duration. This approach is applied to a real utility distribution
network, with the results presented and discussed.N/
