Optimization of Investments in Photovoltaic Microgeneration for Self-Consumption with Grid Injection

This research focuses on the development of a technical-economic evaluation model that can optimize investments in micro solar generation, taking as a case study a poultry farm and considering technical and economic aspects of the project. The profitability is evaluated using NPV and IRR, with values that were favorable and determine the profitability of the investment in photovoltaic micro generation with the values obtained. In the optimization, a linear programming model is used with AMPL software, which allows to parameterize the information of the decision variables and optimize the costs with the modeling of the possible operating scenarios. The initial investment is reduced by 12% and the economic viability of the project is determined in spite of the existing cost and subsidy policies in the country for the different types of clients.
