ABSTRACT: 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-criterion 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 the results comprehend the savings for this consumer, considering the
methodology application. The main result is a reduction in energy costs by 33.3%,
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 theoretical 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 30.2%,
considering the situation without this methodology. In conclusion, the results
show that the developed methodology is effective. In the two case studies
presented there are significant savings for the consumer.
