Óptima determinación de la capacidad en transformadores de distribución considerando costos asociados a la inversión y pérdidas, usando programación no lineal entera mixta y bajo escenarios de demanda

Abstract

Both technical and economic performance in power distribution networks are the essential motivations for electric companies to optimize their investment, particularly in relevant elements such as distribution transformers, which are widely used in the network. Electric companies usually allocate a large part of their budget in the installation of transformers to supply new loads or increase the capacity of distribution transformers to meet the growth in demand and the system’s reliability each year. Therefore, the present paper develops an optimization model that allows integrally including the impact of the initial investment of transformers and the cost of electrical energy losses within the economic service period, allowing in this way, obtain the optimal results associated with the technical and economic selection of transformer capacity, and; model is checked under different load scenarios.
