Context: This article presents an evaluation method for penetration of solar photovoltaic energy in distribution systems. This evaluation considers cost minimization of energy losses during the lifetime of the solar photovoltaic panels and includes calculation of total costs of energy, and investment, operation and maintenance of the panels. Method: The parameters used in this study are based on recent studies in Colombia with the purpose of proposing more realistic alternatives. The optimization problem is solved using a specialized genetic algorithm and the method is tested on the IEEE 37-bus test-system modified, to include behavior of residential and industrial loads. Results: Power losses in feeders are graphically presented as a relationship with the number of buses with photovoltaic panels. The farther buses from the power supply are more attractive for the location of photovoltaic panels in terms of investment and total cost of energy. Conclusions: Results of the evaluation presents a reduction of power losses in lines. In addition, it shows the advantages of local reactive power support. According to the scenario, it shows that it is possible to generate with photovoltaic panels obtaining an investment return from the perspective of the network operator and investor.
