Abstract
Improving the understanding of the dynamic response of electrical power systems to disturbances is a topic of high interest both for the academic community and for network operators who must take measures to guarantee the stability of the system. So, the following document proposes a comparative study of operating scenarios through the implementation of a simulation tool to study the transient stability of microgrids with synchronous generation connected to the electrical power system. Matlab-Simulink has been used for its development. From this computational tool, the simulation of the dynamic response of a typical microgrid with synchronous generation is carried out, in order to evaluate its angle stability against a fault condition in different stages. This is done in four cases, the first is a base case, with values in per unit specified in the methodological development, from which the critical time of fault clearance is determined; in the second, its H value is increased by 20%; in case 3 the base case is modified by increasing the maximum power during the failure, finally in case 4 the base case is modified by increasing the maximum power by 20% before and after failure. The different responses of the system are compared and analyzed in the results discussion section.
