%X The objective of this work is to reduce energy costs for a consumer with
multiple available energy resources and with an energy storage system. To
achieve this, it is developed a methodology with a multi-criterio</span></span><span><span><span style=\"font-family:&quot;\">n</span></span></span><span><span><span style=\"font-family:&quot;\"> analysis
that considers the demand side, the real-time prices, and the availability of
the energy resources. In other words, the developed methodology manages the
multi-source system, allowing savings for a consumer. In addition to the
presentation of the methodology, it is made an application in a case study. It
is considered and modeled a real consumer that has three different energy
resources, including energy storage by battery. The situation comprehends solar
generation, diesel generator and the electrical power grid. There are
simulations and </span></span></span><span><span><span style=\"font-family:&quot;\">the</span></span></span><span><span><span style=\"font-family:&quot;\"> results comprehend the savings for this consumer, considering the
methodology application. The main result is a reduction in energy costs by 33</span></span></span><span><span><span style=\"font-family:&quot;\">.</span></span></span><span><span><span style=\"font-family:&quot;\">3%,
considering the situation without this methodology. For the purpose of
indicating the use of the storage system, it is presented the battery¡¯s state
of charge along the simulation. Also, there is a verification of the
methodology¡¯s robustness, through another simulation, using theo</span></span></span><span><span><span style=\"font-family:&quot;\">ret</span></span></span><span><span><span style=\"font-family:&quot;\">ical data for the consumer. In this case, the consumer has energy storage
system, solar generation, biogas generator and the electrical power grid. In
this situation, there is a reduction in energy costs by 30</span></span></span><span><span><span style=\"font-family:&quot;\">.</span></span></span><span><span><span style=\"font-family:&quot;\">2%,
considering the situation without this methodology. In conclusion, the results
show that the developed methodology is effective. In the two case studies
presented there </span></span></span><span><span><span style=\"font-family:&quot;\">are</span></span></span><span><span><span style=\"font-family:&quot;\"> significant savings for the consumer.
