Optimized allocation of self-generated energy: a case study of a brazilian company

Usually, agents in the Free Energy Contracting Environment (ACL) in Brazil, as self-producers and independent producers with their loads, must be carried out an accounting routine named allocation of self-generated energy (AGP). Considering the lack of specific works to solve such typical and necessary routines of these agents, this work presents a methodology to optimize the allocation of self-generated energy. The main contributions of this work are: (i) the elaboration of the allocation of self-generated mechanism as an optimization problem; (ii) development of a free software that provides the values to be allocated to each consumer unit in order to obtain the greatest gain with the distribution of the agent’s generation and (iii) enable an allocation analysis in order to obtain the predictability of earnings with allocation in a given future period. In case study, we used data based on a large Brazilian organization in the Steel/Metallurgy/Mining sectors. In a comparative analysis, the simulation using the optimization process guarantee a financial gain of 17%, which represents savings of 3.6 million in Brazilian currency.
