Popis: The ongoing energy transition comes with significant challenges that require grid operators to adapt the electrical network with the needed technologies. With the current rate of electrification and decarbonization, it is essential to implement changes on overall infrastructures, since incidents related with lack of grid modernization may constitute a significant problem in the network of the future. One way of tackling some of these challenges is implementing a battery energy storage system, since batteries have a variety of functionalities that can operate simultaneously, allowing different problems to be addressed by one common solution. Due to its growth in the past decades, leading to costs reductions and technological advancements, batteries evolved to be a popular choice for electrical substations and are now widely used in this field. Therefore, this thesis focuses on the development of a digital model in DIgSILET PowerFactory, a power analysis software, where it is possible to simulate the electrical network in big detail and perform a variety of simulation to determine which is the best connecting point for a battery in distribution grid. Thus, a case study is chosen following several educated assumptions and conclusions and the respective grid and all its elements are modeled. Once all the necessary components are specified, a battery system is connected to the grid and the real hourly power profiles for 2021 for the loads of the case study are input in the program, as to allow an accurate simulation. This is evaluated for four different scenarios in which the power profiles and the connection point for the battery are changed, in order to conclude on the best application case. Finally, a load flow analysis is run for all scenarios and the results are compared, mainly focusing on how the battery performs in terms of reducing transformers overloading and voltage variability for connected busbars. Once the results are compared and discussed, it is possible to take a conclusion on the best connection point for the battery regarding the chosen case study and the usability of the model to perform future evaluations Objectius de Desenvolupament Sostenible::7 - Energia Assequible i No Contaminant::7.b - Per a 2030, ampliar la infraestructura i millorar la tecnologia per tal d’oferir serveis d’energia moderns i sos­tenibles per a tots els països en desenvolupament, en particular els països menys avançats, els petits estats insulars en desenvolupament i els països en desenvolupament sense litoral, d’acord amb els programes de suport respectius
