Energy Management by the Consumer with Photovoltaic Generation: Brazilian Market

The use of small renewable energies to supply the consumers are being increasingly encouraged, mainly by reducing the environmental impacts, the diversity of the energy matrix and the possibility to delay conventional energy transmission and distribution infrastructure expansion. Allied to this, there are government incentives for consumers to adopt this measure of generation. In Brazil, the National Electric Energy Agency (ANEEL) by Normative Resolution 482/2012, encourages the implementation of energy generation (here called micro and mini generation) from renewable sources for their own consumption. The main objective of this work is to illustrate a possible energy management for the consumer side with photovoltaic generation. Thus, the problem can be mathematically modeled as an optimization problem, which allows consumers to manage their energy consumption, according to their priority of use, meeting part of its consumption by photovoltaic generating and also considering different values of energy tariffs. This optimization problem is a linear programming, implemented by a simulator, which is used to analyze scenarios for the consumer and to assist their energy management.
