Resumo:
Increasingly, the use of batteries for the use of energy from renewable sources, peak
cuts, shifting demand for times when energy is cheaper, in cases of large
storerooms, as well as improving the quality indices of the energy supplied by the
concessionaire. Based on this scenario, the present study evaluates the most
efficient way of using batteries for the case of consumers who use differentiated
charging, Blue or Green Rate. The result of the study that was done based on the
load profile of a phase of the CJ block belonging to the Federal University of
Campina Grande showed that there are two schedules of high peak demand
between 11h and 17h30min, making the use of energy unfeasible for charging the
batteries. Finally, the study used previous work methodologies to size the bank of
batteries that can be used for peak cutting of the studied load profile. The
methodology relates the useful life in a cycling regime with the useful life in flotation
to find an optimum discharge depth that increases the life of the batteries with the
use of at most one daily discharge.
