Evaluación del impacto de microclimas en un sistema de distribución de energía con masificación de sistemas fotovoltaicos interconectados a la red: Caso de estudio en la ciudad de Bogotá

Abstract

This paper evaluates the impact produced by the different types of microclimates in a typical Bogotá energy distribution system, with massification of photovoltaic systems interconnected to the grid (SFIR). The integration of SFIR contemplating forecasts based on historical data with variability due to microclimates arises from the need to identify the possible negative effects on a distribution system, due to its low investment cost and technical-financial viability in cities with good quality of service. energy like the city of Bogotá. Taking this into account, a case study methodology composed of four simulation scenarios is used to analyze the impact of microclimates on the voltage profile, losses, and chargeability of transformers and lines. The case study is structured in three phases. In the first, an analysis of climatic variations is carried out through the level of dispersion of the measurements provided by different meteorological stations of the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM). In the second phase, the distribution network of the National University (Bogotá campus) is modeled with high SFIR penetration in the DIgSILENT software. This phase is complemented by load variations and microclimatic characteristics identified in the first phase. In the last phase, an analysis of the impact of the different characterized microclimates is carried out. Finally, it is determined that there is no significant impact of microclimates on the distribution SFIR since a change of approximately $1.7\%$ is obtained between the weather stations of the National University and IDEAM.
