Impacts on electrical protections in radial distribution networks with distributed generation, considering a high penetration of sources based on invertersThis document analyzes the time response of two electrical protection schemes in different scenarios of distributed generation. Its implementation is carried out in the 13-node IEEE system, to which modifications were made in order to simulate a typical 13.2kV electrical network in Colombia. Initially, there is presented a theoretical part in which the characteristics of electrical protections and the main protection schemes implemented for distribution networks are explained, to later analyze the case studies and their considerations.Finally, the results of the simulations obtained for each of the selected protection coordination schemes are presented, taking into consideration the scenarios of minimum and maximum demand of the system. The different fault impedances that can occur and the types of generation connected to the distribution network are also taken into account (synchronous generators and static generators).
