Economic Analysis for Brazil Residential Consumers Considering the Time-of-use Tariffs and Demand Side Management of Electricity Using HOMER PRO Energy.

Abstract

Between tendencies of contemporary word, it is the growth of need energy supply and the increase environmental concerns. Other advantages of energy use associated with distributed photovoltaic generation are the reduction of greenhouse gases, the reduction of demand for power generation, the reduction or the replacement of investment in generation, transmission and distribution, and the increase the availability of energy supply. If, on the one hand, renewable sources of energy, like solar, wind and biomass, it has lower environmental impact at power generation, the insertion of these sources requires investments, which should be carefully analyzed, aiming to obtain the best cost-benefit of the implanted technology. In addition, it is important to highlight the use of energy use of equipment more efficient, in other words, the possibility of a demand side management like the use of solar heating equipment. In this context, it can think about the importance of simulation technologies, which address not only economic issues, but also environmental and electrical issues. To carry out a technical economic-environmental analysis, simulations were performed using the computational tool HOMER PRO Energy applied to residential consumers. A comparative study was conducted considering the option of “Time-of-Use Tariffs”, the load profile take into account the electric shower and the use of solar heating system and a grid-connected photovoltaic system.
