This paper presents an analysis of the behavior of the IEEE 30-node distribution system in presence of short duration variations; specifically sags and swells are assessed before and after implementation of SVC (Static Var Compensator) and DSTATCOM (Distribution Static Compensator). The magnitude for sags and swells is selected according to what is specified in standard IEEE 1159: 2009 and NTC 5000: 2013. An algorithm is implemented in MATLAB to find the power flow solution based on the Newton-Raphson method, in which the SVC and DSTATCOM compensators are included. To validate the algorithm, a test for a 5-bus system, is conducted. In the IEEE 30-bus system, load values are changed in order to generate the sags and swells under analysis; the case study focuses on the behavior of node 10. The findings suggest that although the values of power delivered (or absorbed) by the SVC and DSTATCOM compensators for the same event are different, all nodes maintain voltage levels between 0.9 and 1.1 p.u.
