Black start refers to the process of restoring a power system after a black out. Although black outs occur seldom, it is critical for reliability and resilience to have effective black start procedures. A black start consists in re-connecting and re-synchronizing generators and loads sequentially. PSS/E is a power system simulation software that allows simulating in the time domain the impact of a variety of disturbances on power systems. PSS/E does not consider black start explicitly so far. This project aims at implementing functionalities and codes to simulate a black start in PSS/E. In particular, the re-synchronization of a generator to an already restored part of the power system will be considered, which intentionally overlooks the problem of starting up a generator. The re-synchronization could be done for instance by operating the generator and its transformer without load and in islanded mode and by adjusting the angle of the voltage of the generator (slack bus) before closing the breaker. The tasks are the following: 1) understanding black start 2) implementing functionalities and codes to re-synchronize a generator 3) simulation of a black start
