Implementación en ATP de benchmark IEEE 39 barras incluyendo modelos genéricos de generación fotovoltaica para estudios de integración de energías renovables a la red

Abstract

The increase in electrical energy consumption requires the study and development of different generation technologies that allow supplying demand with efficiency, quality and safety. The work presents a contribution to the analysis of the dynamic response of an electrical power system to the input and output of photovoltaic generation in the Alternative Transients Program (ATP) software, which is of the EMT (Electromagnetic Transient) type, considering an adequate level detail of its components that allow analysis using effective values - RMS. For this, the 39-bar IEEE test model is implemented with the respective control systems of the synchronous machines, using IEEE models implemented through TACS. The approach of this work allows us to analyze the response of an electrical system that has conventional generation units, to the entry of generation based on sources that are connected by inverters. The entry of large blocks of this type of generation reduces the inertia of the system and power reserves which, in dynamic events, can lead to a loss of the system due to frequency. From this point of view, frequency response analysis is important to determine the amount of inverter-based generation that can be connected to a grid. A simulated power system in the ATP software allows it to be studied at a high level of detail and precision, obtaining response signals in the phase domain. This allows the model to be used for the analysis of slow transients and fast transients, contributing to the research of new technologies in generation. Photovoltaic systems are currently more accessible, so their integration into the SEP requires appropriate models for research and studies. Having the models, as well as the system and its integration in this type of software, allows having a detailed reference scenario for EMT studies of a power system.
