ABSTRACT: Joule losses in the power grids are a factor in the degradation of power
grid equipment (lines and transformers), but also a shortfall for power
companies, which must maximize their revenues. This is why in this article we
present a study on the optimization of joule losses in a meshed electricity network
interconnected to a very high voltage power line crossing Congolese territory
for nearly one thousand five hundred (1500) kilometers. The value of
interconnections no longer needs to be demonstrated in view of these technical,
economic and social advantages. The object of this study is to assess the
optimal node where the interconnection can be achieved which would cause fewer
joule losses in the networks to be interconnected on this line. Indeed, it can
have several possible nodes where the interconnection can be carried out, so it
is necessary to simulate each configuration in order to evaluate the losses
using the hybrid method including the genetic algorithm to provide different configurations
and the Newton Raphson algorithm. Advanced integrating FACTS devices in this
case STATCOM to perform load flow. The results are interesting because by
injecting electrical energy to the network or to the line to the same selected,
the joule losses are within the standards provided by the International Electrotechnical
Commission.
