Alocação de recursos energéticos em uma comunidade de prossumidores

Abstract

In Brazil in recent years there has been a significant growth of photovoltaic generation installed directly in the consumer units, constituting the so-called prosumidores. However, the vast majority of these facilities occur in an individual way, in the mode of self-consumption and adhering to the compensation system. Few units take advantage of the possibility of forming an enterprise with multiple consumer units. This work aimed to evaluate the benefits of the prosumers when joining the compensation system individually or in community. Thus, a mixed integer linear programming model was used to select and operate photovoltaic generation technologies, considering the Brazilian compensation system in order to minimize the annualized total cost to meet the demand of the prosumers. Tests were conducted for prosumers connected individually and in virtual communities, for two tariff modalities, conventional and white. The results showed that when the variable analyzed is the tariff modality, there is a small increase in the benefit obtained by the individually connected prosumer. However, when the option is to connect in community the benefit may have a more significant increase. It is concluded that the formation of communities of prosumidores can be considered economically attractive when using photovoltaic generation, not being so evident the benefit when the investment is realized of individual form for each consumer.
