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.
Highlights
The search for energy cost reduction by consumers has become increasingly frequent
The simulation occurs for one day
As it is described on item 4 the results can be presented in two points: the costs savings and the level of the energy storage system (ESS)
Summary
With the expansion of other energy sources in the world energy matrix, there is an increase in the demand for other energy resources for energy supply and, the search for multi-source systems. Since 1990 the electricity consumption per capita raised from 2.1 MWh to 3.3 MWh in 2018, which represents an increase of 57.1% in 28 years, according to IEA1 data. This situation leads to increase in the diversity of generation sources of energy, such as hydroelectric, diesel, solar, wind, etc. As it can be seen, the variety of energy resources has increased since 1990
